AMD's Ryzen CPUs (Ryzen/TR/Epyc) & Vega/Polaris/Navi GPUs

"Killing" isn't an appropriate overall label.

In compression the Intel CPU's are known to do better, not just on ThreadRipper, but on the other Ryzen CPU's too, the decompression reverses this, and with 8 core, 16 core and 32 core ThreadRipper 2990WX that scales as expected:

" There's no apparent change in the decompression performance by moving between one, two, or four dies on the 32-core Threadripper"

"The 7-Zip LZMA decompression is more sensitive to integer, branch prediction, and instruction latency. Although Core i9 has some advantage, it's clear that more cores are better in the end."

Memory IO is split across the only external connections, and so of course the bandwidth per core is going to go down as you use cores 17-32. If you aren't using all 32 cores, the worst case divisor the per core bandwidth is higher - closer to the full 1-16 core per core bandwidth.

And, the increasingly limited bandwidth per core from 17 cores to 32 cores didn't affect decompression scaling, and compression / decompression should need similar memory IO, if coded well.

The compression algorithm's favor Intel, even against full memory bandwidth, but it looks like the compression algorithm breaks down on lzma with less bandwidth - perhaps some intelligent staggering of IO across cores would help the result?

As AMD would say, if your primary workloads are affected by the shared bandwidth of 2990wx cores 17-32, it's time to move up to the fully connected CCX's of the Epyc CPU's.

Or, get two 1950x's or two 2950x's and run 2 encoding workstations.

EVGA RTX2080TI iCX2 Misrepresentation ( self.nvidia)
submitted 6 hours ago by _aesynk to r/nvidia
https://www.reddit.com/r/nvidia/comments/9dq97v/evga_rtx2080ti_icx2_misrepresentation/

"On August 20th when preorders went live after the livestream I snatched one up instantly. Coming from FE 1080's I was excited to give EVGA a go with their reputation of having great products and customer service. Reading about the quieter cooler, and thermal sensors really intrigued me since they say these cards are overclocking monsters and my FE 1080's throttled themselves base clock.. womp womp. I thought great, I can get a great AIB TI day one and forgo all that headache. I preordered.

Then Aug 30th - I came across /u/EVGA_LEE's comment on their launch thread

"The Pre-order cards are not iCX2. The upcoming XC2 and FTW3 cards will have iCX2. "

Up until about a week ago EVGA's product page for the XC Gaming / XC Gaming Ultra displayed the following in the OVERVIEW section of their cards respective product pages. Mentioning iCX2 and the sensors.

Spoiler: Details...

EVGA GeForce RTX 2080 Ti XC Gaming
Everything is new

Completely Redesigned From the Ground Up:

• Redesigned iCX2 Cooling is 14% Cooler and 19% Quieter
• With the EVGA GeForce RTX 20-series Graphics Cards you get the best gaming experience with next generation graphics performance, ice cold cooling with EVGA iCX2, and advanced overclocking features with the all new EVGA Precision X1 software.
• Incredible Cooling The next generation in cooling is here with EVGA iCX2. This new cooling solution offers improved cooling, lower noise levels, real time wattage monitoring and 9 additional thermal sensors for 'Peace of Mind Gaming.'

Here are the images saved.

Original Overview : https://i.imgur.com/WJEBqIs.jpg

Highlighted Original Overview: https://i.imgur.com/oGAIRJN.jpg
--
I touched base with EVGA and provided screenshots ( the highlighted image) to ask them to clarify..
Their Response:

this is an advertisement page about future cards along with the ones we are releasing first.

We did not mislead anyone into thinking the cards that will be arriving first have this technology as these are still in development.

So the overview section of the product page for the $1200 XC Gaming / Ultra's is an advertisement page about future cards? I think not. The name of the card is in huge letters at the top, Even the file name of the overview image is literally the product number of the card. The ineptitude of EVGA's employees of their own website is pretty shocking.
--
That night I setup a simple Powershell script that requests the product page/image once every 30 minutes and on detected change save it and render a PDF of the page. The next evening I was surprised that my script had triggered at least 16 times over a 24 hour period. The image has indeed been changed (detected by raw file size)

Changed Overview Image: https://i.imgur.com/Rg5p8FZ.jpg

Which has been scrubbed of all mention of iCX2. I wonder why that is? I replied to the email ticket I have detected a change in the image where all mention of iCX2 was scrubbed and attached multiple screenshots and the image saved directly (linked above), and that the website is serving two different images randomly and they should check their caching service. As a developer myself I knew it had to be a caching issue on their side, which just shows more ineptitude on EVGA's part.

Their Response:

I am not aware of any changes that were made. Nothing was altered and I am not sure where you are getting this information.

Uh, it's a screenshot of your website and image saved from the product page - Duh. So I replied back pretty heated drawing it out so easy a 5 year old could understand.
--
A wild /u/EVGA_LEE appears
--
A customer sent an email asking for clarification earlier in the week to confirm that the card was not iCX2, and we updated the Overview/A+ content because the iCX2 references section was not meant to be in the final image

Secondly, you are likely seeing multiple cached versions of the Overview/A+ content on those pages, as we did not purge the cache until today. In hindsight, it should have been done sooner, but you are the first person I’ve seen mention seeing multiple versions of the A+ content.

So yeah, EVGA misrepresented the features of their cards, that they already took the money for and after the fact changed the image when brought to their attention. But botches their caching service so the original/corrected images are displayed randomly on their website until they cleared the cache upon my *****ing which "should have been done sooner" tsk tsk tsk... Pretty shocking for a company with "intelligent" in their slogan.

I floated the idea to Lee that perhaps since they misrepresented their products and admitted to it, and didn't bother letting the people who preordered them know about it - outside of a Reddit comment - they should offer a free step up when the iCX2 cards become available - After all they are the ones who misrepresented the features of their products. Seemed like a fair compromise on their part I thought, as I only want what they advertised I was buying, I expect nothing more.

Instead I get offered

We can offer you a cancellation/refund for your XC card, and reserve an iCX2 card of your choice to purchase when they are available for sale. We would not waive the difference in price between the pre-order and an iCX2 card. At current expectation, you would likely be waiting 7-14 business days longer for an iCX2 card, than if you kept the pre-order. This is the best estimation I can give you at this time. Either way, you would be first-in-line for the model of your choice. Keep in mind, however, that the dates may change; however, the dates would apply to everyone waiting for these cards, not just you. If so, I will update you accordingly.

So yes, make the customer compromise because of your mistakes while EVGA literally takes zero responsibility. Obviously waiting even longer for a card for my new build, while shelling out more cash due to them misrepresenting their products didn't fly with me and I've canceled my pre-order.
---
What's even more comical is, they not only botched updating their OWN website but they also failed to update the information to their re-sellers like Newegg which still reference iCX2. Truly amateur hour over at EVGA.

While EVGA didn't shoot my dog and burn my house down I find this all a bit concerning, so I figured I'd let you guys know how they've handled misrepresenting their products. I don't care that they wont upgrade me to the card with the iCX2 feature as I've already secured another 2080TI, this is not what this is about. Companies should take ownership of their mistakes and attempt to make it right with their customers - Not say **** off cancel your order, or give us more money.

So if you got a EVGA pre-order card and thought you were getting iCX2 - You're not. I will say EVGA were quick to refund me so at least their accounting department has a higher level of intelligence than the other people I've spoken to.

At least there's that.

$400 12-core Threadripper: But Is It Worth It?
Threadripper 1920X on the Cheap
By Steven Walton on August 29, 2018
https://www.techspot.com/review/1686-affordable-12-core-threadripper/

"With AMD's 2nd generation Threadripper out in the wild, the company has decided to slash prices of first gen parts. So far only the 32-core 2990WX and 16-core 2950X have been unleashed, while the 12 and 24-core versions will arrive in about two more months.

In the meantime, AMD quietly reduced the Threadripper 1920X's SEP, short for "Suggested E-tailer Price," down from its launch price of $800 to just $400. On paper, for $400 a 12-core/24-thread high-end desktop processor is an incredible buy.

To help put this into perspective, you can expect to pay roughly the same amount for Intel’s Core i7-7800X, which has half as many cores. Meanwhile, Intel’s 10-core 7900X still costs $1000, so at least when compared to Intel high-end desktop offerings the 1920X is an insane bargain.

Be aware it’s not yet clear if this sale will continue while stock remains or if AMD will revert back pricing. The information we have right now suggests that the sale will run until the end of August, though AMD may continue to offer retailers rebates so they can maintain the sale price until stock runs out.

Having that said, even at the new low price you’re still paying a decent premium over more mainstream parts such as the 2700X. Granted the 1920X only costs 20% more at the new price and packs 50% more cores, but motherboard prices do inflate the platform cost quite considerably.

For example the 2700X with a high quality B450 motherboard such as the MSI Tomahawk version will set you back $430, meanwhile the 1920X with the cheapest X399 board will cost $700, so a little over 60% more expensive. Factoring in memory doesn’t help much as you need a minimum of 4 sticks for the X399 platform, but that can also be viewed as a bonus, we’ll discuss all this towards the end of the article once we’ve gone over the performance benefits.

Let’s quickly jump into the benchmarks, and then work out who this affordable 12-core processor is for.

All testing was conducted on the MSI MEG X399 Creation using 32GB of G.Skill FlareX DDR4-3200 memory. The performance will be achievable on any and all X399 motherboards and for the 1920X we recommend budget boards from MSI, Asrock and Asus..."

" Benchmarks
As I said we’m just going to breeze through all the testing. As you can see for rendering tasks you’re looking at around a 40% performance uplift with the 1920X over the 2700X and an incredible 90% boost over Intel similarly priced 7800X."

New GeForce Driver Fixes Performance Issue: Threadripper 2990WX Tested

New GeForce Driver Fixes Performance Issue: Threadripper 2990WX Tested
https://www.reddit.com/r/hardware/comments/9ezpbk/new_geforce_driver_fixes_performance_issue/

Re-tests comparing new Nvidia 399.24 vs 398.26 drivers with fix:




"Overall, we are quite impressed with the performance increase this new GeForce driver provides over previous drivers when it comes to the 32-core Ryzen Threadripper 2990WX. Almost every title we tested saw some sort of frame rate increase, up to 78% for the most improved title, F1 2017.

However, there are still some caveats to recommending the Ryzen Threadripper 2990WX to content creators who are also interested in gaming. We saw some heavy stuttering while testing in a few titles, namely Assassin's Creed: Origins and F1 2017 that was not present while testing the same platform in 1/4 core mode.

We've passed this data onto NVIDIA and hope they will continue to refine how their driver handles these extremely high-core count processors..."

pcper ends on a sour note blaming AMD for releasing the CPU with known gaming bugs, even though it's a workstation CPU.

The good news is Nvidia and AMD seem to have already been on this issue, otherwise the update wouldn't have mentioned fixing it specifically. It also looks like there are future optimizations in Nvidia drivers that could help, not a surprise either. It even happens with their own GPU's.

 

Advanced Micro Devices CEO: Leading Technology | Mad Money | CNBC
CNBC Television
Published on Sep 12, 2018
It’s involved in gaming, PCs and the data center and its stock is up a whopping 190 percent this year alone. Could the move in AMD continue? Jim Cramer sits down with its bankable CEO, Dr. Lisa Su.

 

This is actually why I only use PCPer for their review of harddrives and SSDs. The bias is HEAVY at that publication. If a driver from Nvidia fixed the problem, then it was Nvidia's driver that did not play well with the new hardware, not the new hardware's fault. Also, correction within a month of launch is fairly reasonable to correct the issue. So, yay for hardware companies addressing faults! Meanwhile, where is M$ fixing that performance deficit between it and linux? Turns out the 20% deficit hits the 8700K just like it does all AMD zen based chips, meaning everyone would benefit from M$ fixing their stuff. Also, where is a more advanced scheduler that can take advantage of different system topologies for memory access, etc., that way to minimize the tasks scheduled for bouncing to other memory controllers, other dies and caches, etc.? Sure, they improved from Ryzen 1800X launch, but that doesn't mean the job is done. Rethinking the scheduler to address the emerging white papers on topologies, uarch, etc. so that it benefits both current and potential future designs, considering chiplets are the first major change since multi-socket boards and Intel's original dual core which was roughly similar to the current zen split, to a degree. But, they are too busy telling corps that if they want Win 7 after 2020 with security updates, they have to pay. But I digress.

Edit: Actually, even with the bit of blaming done by Ryan, the statement is more fair than I have seen PCPer be in awhile. I may not fully agree with the assessment, but he did drop in potential blame on Nvidia also, and acknowledges it is all a mess. But, part of the reason it is a mess is things are changing in the industry, especially with Intel's security issues, process issues, and supply issues, all things Intel used to say about AMD. But, because of that acknowledgment and the slight softening of tone, I will share the final summation note of Ryan's here (also, note, they received zero pressure from AMD to change their findings or testing methodology, which means they did not try to force a good review from channels, which from that description, to me, suggests certain other companies may make those comments or try to force other testing, like Intel suggesting 720p testing when the first mainstream Ryzen chips dropped) -


"Ryan's Note: This is an interesting shift in performance that lends itself to a deeper discussion at some point in the future. First, if this was indeed just a bug in the NVIDIA driver itself, the timing of it could not have been worse for AMD, as the window of time it existed is very closely matched with the release of the 2nd Generation Threadripper reviews. Second, this does make us alter our view of the Threadripper 2990WX. As Ken noted, the processor still has complications for gaming caused by its architecture but the picture is improved dramatically with these updated results.

It also reveals a shortcoming of our gaming testing, and the gaming testing of most of the online community - we only tested with a single graphics card. We use a GeForce GTX 1080 Ti for our CPU reviews because NVIDIA has been known to have better performance and better driver stability, but this situation has us a bit concerned. Best case is we double our workload and test a Radeon graphics card too. But then that can waterfall to different architectures (why not Turing AND Pascal, or Vega AND Polaris?), different driver versions, etc. It's a tough battle for us to face.

For AMD itself, this is a learning opportunity. The company said nothing to us to make us second guess our results, or push us to do Vega-based testing that would have shown the 2990WX in a more positive light. If the engineers were doing in-line testing for some longer period of time during product development, they would have seen this sudden drop in 2990WX gaming performance with a specific NVIDIA driver drop, and know to address it with NVIDIA or the media. Instead, it seems that everyone involved was in the dark. (Though AMD was leaning on the WX-line as a workstation only part, it surely was doing some kind of gaming testing.) Maybe NVIDIA knew about the bug - but rather than inform the community, it decided to let the reviews of the AMD Threadripper processors go out unfettered.

The whole situation has really been a mess." - https://www.pcper.com/reviews/Graphics-Cards/New-GeForce-Driver-Fixes-Performance-Issue-Threadripper-2990WX-Tested

 

Only thing I didn't like in that interview was not holding her feet to the fire on graphics cards. Personally, for midrange cards, I think AMD is highly competitive, especially with prices returning to normal. But, even with Vega being competitive with Nvidia on 1070 and 1080, I do still feel that the flagship has little competition, especially if the Ti price falls further after the RTX release. The 2080 is flat with 1080 Ti in my opinion, so I consider them to be competitors with each other, but, even the Navi 10 is expected to go against the 1080, which is the 2070. If true, it will be above the 1070/2060, which is pretty good for the replacement to the 500 series. If, instead, it is just under the 1080/2070, but above the 1070/2060, AMD will have a great price point and fight on their hands, while ceding any level above that. That is fine considering the die size reduction to increase yield on 7nm could create a very good recoup through volume production, especially since this was made for Sony. But, the monolith 7nm Navi 20 doesn't come out until 2020, which then will combat the 7nm Nvidia cards which will have the process jump advantage for increasing their performance while AMD would only have the advantage of not using quad patterning and the tweaks TSMC makes to 7nm, along with increasing the die size/transistor count. I have no doubt that super-simd will improve performance, but still need numbers (also should speed parallel processing and potentially async compute even further, which AMD's Vega still seems more apt at than the Volta and Turing uarchs, although testing on that will be out in like a week).

But that is my analysis and understanding of the GPU side to this point.

AMD Allegedly Readies X499 HEDT Platform For Ryzen Threadripper CPUs, Aiming CES 2019 “AMD Tech Day” Announcement
By Hassan Mujtaba, Sep 7 2018
https://wccftech.com/amd-epyc-rome-7nm-64-core-cpu-performance-benchmark-leak/

"While AMD allows their 2nd Generation Ryzen Threadripper processors to run on existing and refreshed X399 motherboards, rumor is that AMD will also offer the high-end X499 platform in early 2019.

AMD X499 HEDT Platform Rumored For Ryzen Threadripper CPUs – To Be Announced at CES 2019
The rumor comes from HD-Tecnologia who has revealed in an exclusive post that the AMD X499 will be arriving early next year but after the Intel X599 chipset which will support their Skylake-X core processors featuring up to 28 cores.

Earlier, it was suggested by motherboard manufacturers that the X499 chipset was definitely in the plans but was canned alongside the Z490 mainstream platform. Now, rumors are emerging once again on these two platforms so we might just get to hear about them when the next-generation of Ryzen processors are revealed to the masses. We won’t hold our breathe on these though because this is still just a rumor and we don’t really have a lot of details on any of the respective platforms.

The announcement of the X499 chipset is said to be held at CES 2019 at the AMD Tech Day event for journalists. Talks regarding the next-generation EPYC 7nm processors which are expected to ship later next year along with new Ryzen Threadripper CPUs and Navi GPUs are also said to be held during the event.

We can’t say what the X499 platform is designed for yet but there could be two possibilities. One is that since not many motherboard manufacturers jumped on board to offer X399 refresh solutions, they might have been waiting for the X499 PCH to be ready for the launch of proper high-end desktop boards for the 2nd Generation Ryzen Threadripper processors.

The second is simply that the X499 will be a new platform, offering support for next-generation Ryzen Threadripper CPUs and we have also been hearing the support of octa-channel memory which might make sense since Intel will be offering hexa-channel memory support on their flagship X599 platform.

AMD Ryzen Threadripper 3000 ‘3rd Gen’ HEDT CPUs – 7nm Zen2 Cores For 2019
The Ryzen Threadripper 3rd Gen or 3000 series family is expected to debut in 2019. This family will be internally known as “Castle Peak” and is stated to bring a dominant leadership in the HEDT market. The family will prove to be a new watermark in performance and overall efficiency while new platform features will be introduced on the TR4 socketed motherboards to take them to the next level. We may be looking at PCIe Gen 4.0 support on these motherboards along with a core count bump which is rumored to be happening on the 7nm EPYC ‘Rome’ series by the end this year.

These are all rumors so best is to wait for official information which will arrive in a few months. Let us know your thoughts about the X499 platform in the poll and comments below."

 

Really hope the eight channel thing is true (which if Adored is right with the 32 DIMMs per socket for Epyc, and they are doing a design for TR that is less than that, we could see increased channels on server boards and 8 channels on TR would then not matter and not interfere with the server space, which then makes me hope they bring quad channel to mainstream boards).

 

Any detailed pin out diagrams for TR4? Are there enough "reserved" or convertible pin-out's what would accommodate doubling the memory channels?

I've previously heard that Epyc / TR4 are mechanically the same, but the pin-out's are different... for more channels of memory?

Perhaps it's a matter of unlocking the hidden capability of TR4 in x499?

x499 would be forward (3xxx) / backward (2xxx) compatible, but you'd need a new ThreadRipper 3xxx CPU to take advantage of all the memory channels available in x499.

That would be a nice "surprise", if x499 is where ThreadRipper 3 and Epyc 1/2 memory channel capacity converge?

 

I'll try to find a pinout later. Another way it can be done is a new socket for both, where the X499 basically gets the old server socket, while the Epyc 2 gets a new server socket, other than having the chipset on the board for X499 (something that is on the chip, IIRC, for the server chips). Then, if you put in the older chip, it only sees the slots and channels for what the old chips can do, 4 channel on TR, 8 for Epyc, but where the new chips can read and use 8 for TR3 and 16 for Epyc 2. Just a thought. Kind of how Asus had the extra pins on their socket before the pin count went up for 2011 sockets awhile back.

 

Chilling Threadripper 2!!!
Linus Tech Tips
The benchmarks start at 11:30...CB15 -> 6229
Published on Aug 29, 2018

 

The only thing is AMD is good at providing socket support for 4 generations of CPU's, and TR3 is - the 3rd. So the socket for TR3 needs to be supportive of TR1/TR2 - it's ok to add features only supported by TR3 to the TR4 socket, but it needs to be backward compatible.

If the pin-out's are the difference between Epyc and ThreadRipper, with only the memory channels being different, perhaps there is a way to enable the TR4 pins to supply more memory channels - but still not be pin for pin compatible with Epyc.

Not sure about socket support Epyc, if there are similarly more pins available to activate for additional Epyc memory channels or if there would be another expansion scheme used - maybe a new socket, but maybe something else.

 

This gives a little info on there being an ID pin and him covering the pin and got it to go further in the POST. It didn't complete post, but made it further. Since it has ID pins, and since you can add more pads, where you get double contact on the same pad on older gens, but have individual pads for the new chips, you can set it up so when it gets certain signals by doing so, it knows which mode to kick into for supporting which chip. That allows for backwards and forwards compatibility, even with different pin count, if ever so slightly. Or that would be the way I'd try to design around the issue if more pins were needed.

 

Threadripper 2990WX Performance Regressions? Not so fast...
Level1Techs
Published on Sep 16, 2018
Let's talk about the curious case of the 2990WX performance regressions vs the 2950X where the 2990WX performs worse *on windows* than Linux.

I think the issue goes deeper than scheduling -- something else is broken with this many threads.

I've also seen the recent driver bugs in the nvidia driver for performance regressions there -- it's not as useful to look at that because it's cross platform -- but I suspect that (at least on windows, before "windows 10 for workstations" is a thing) 32 cores is more machine than windows can handle.

I was a bit surprised to confirm the performance delta is as much as it is.

ALSO NOTE: I'm not really wanting to be team red/team blue but with this tweak the 2990WX DESTROYS the 7980XE in Indigo now
For those of you that keep score.

Left out here for time was 7zip. FWIW 7zip behaved wildly inconsistently even doing the powershell thing. In some bench runs I could get similar performance to Linux in but other times the performance regressed

Plus, I'm having an issue with the BIOS I'm using and the PCIe clocking way down, meaning it is giving closer to 1/4 to 1/2 the throughput I got on Windows, which makes graphics on it nowhere near where they should be.

 

AMD details high-performance Ryzen 7 2800H and Ryzen 5 2600H mobile APUs
Jacob Ridley, 9-17-2018
https://www.pcgamesn.com/amd-ryzen-mobile-2800h-2600h

"All the details about AMD’s Ryzen 7 2800H and Ryzen 5 2600H APUs have appeared on the AMD website. These mobile processors both represent the best of the best when it comes to the Raven Ridge lineups, and, in order to hit target performance, ditch the 15W TDP of current U-series chips, instead opting for a configurable TDP of 35-54W.

These chips will require considerably bulkier cooling solutions compared to previous Ryzen U-series. That means neither new chip will make it into miniscule 2-in-1s, instead favouring high-performance laptops and workstations. However, in return for larger form factors, CPU and GPU clocks have seen considerable bumps, which should make these mobile APUs quite tempting to users looking for a little extra graphical performance on the go.

The four-core / eight-thread Ryzen 7 2800H features a 3.3GHz base clock, 3.8GHz boost clock, and 11 Vega CUs clocked to 1.3GHz. That’s just a touch more speed in the GPU department than the Ryzen 2400G, which has proven quite capable of gaming performance – albeit with a slightly more lenient desktop TDP.

The four-core / eight-thread Ryzen 5 2600H comes with a hearty 3.2GHz base clock, 3.6Ghz boost clock, and eight Vega CUs clocked at 1.1GHz. That’s similar to the desktop Ryzen 3 2200G in terms of GPU power alone.

Memory compatibility has seen a considerable bump to 3200MHz with both chips, which could make a noticeable difference to performance depending on if any laptop manufacturers match the top spec with dual-channel memory in any of their machines. Speaking of which, despite a listed launch date of September 10, there’s no confirmed machines featuring these chips just yet.

AMD quietly launched its Ryzen 3 2300X and Ryzen 5 2500X desktop CPUs, intended solely for the prebuilt market, just last week, so it’s unsurprising the red team didn’t make a big song and dance about these new additions to the mobile market either. After all, these Raven Ridge chips are arriving many months after the first batch of mobile APUs, the Ryzen U-series, launched back in February."

AMD quietly launches new Ryzen laptop CPUs with Vega graphics
Desktop horsepower in a notebook APU
By Paul Taylor, Today 10:53 AM
https://www.techspot.com/news/76485...n-laptop-cpus-vega.html?source=indiekings.com

" Why it matters: AMD is using GlobalFoundries to repackage 2400G and 2200G Ryzen processors into a notebook package (FP5 BGA) which will allow consumers to enjoy desktop-class performance in a notebook-class device.

Spoiler

AMD has discreetly introduced two new laptop APUs dubbed the Ryzen 7 2800H and Ryzen 5 2600H, based on the Raven Ridge design, with Vega-powered graphics, for the gaming notebook segment.

While the company has made no official announcement, these can now be found on AMD's website listings for mobile processors.

The Ryzen 7 2800H boasts a base clock of 3.3GHz and a max boost clock of 3.8GHz. It also features 704 SP (11 compute units, 64 stream processors per unit), clocked at 1300MHz. Its little brother, the Ryzen 5 2600H sports a base clock of 3.2GHz and a max boost of 3.6GHz, with considerably less GPU horsepower (512 stream processors). The Vega GPU cores are clocked at 1100MHz. In both cases, AMD has also improved memory support for DDR4-3200, which should help feed those hungry GPU cores in that shared memory configuration.

Despite being classed in separate Ryzen families (i.e. Ryzen 5 and Ryzen 7), both APUs are four-core eight-thread designs. These can be configured to work in 35~54W TDP scenarios, which give notebook manufacturers more options than Raven Ridge (15W).

Looking at AMD's current roster of APUs, the 2800H and 2600H take pages from the desktop 2400G and 2200G playbook, with similar design characteristics, but overall, the 2800H will be a faster gaming processor than the desktop, 65W, Ryzen 5 2400G due to its higher-clock GPU cores and the increased bandwidth when using DDR4 3200. The 2400G, in fact, is so similar to the 2800H, we believe we are looking at the same CPU, but possibly a different stepping, with better (and configurable) thermals, in the FP5 packaging. The Ryzen 5 2600H on the other hand is a clone of the 2200G in much the same way.

Like the 2400G and 2200G before them, the new APUs support SenseMI and FreeSync. As BGA-mounted CPUs, however, no retail pricing is provided for these CPUs as they exist, generally, as OEM components.

AMD continues to manufacture its mobile processors at GlobalFoundries and are yet to take full advantage of the most advanced fabrication process available (12nm at TSMC). AMD's Picasso and Matisse designs are expected to turn up next year, built on Zen+ (12nm), which would take the APU manufacturing away from GlobalFoundries and to TSMC.

First benchmark results, more coming. Turns out that some performance issues we (and likely others) experienced was down to a bios bug. GB has provided Level1 with a fix, which we have posted here:

https://forum.level1techs.com/t/aor...nor-fix-for-linux-other-fixes-gigabyte/132719

Far as we know The TX4 bios is otherwise not available anywhere else. The fixes here will be integrated with the updated AGESA in just a few weeks, hopefully!

Settings changed for PBO to work right:
Set the over voltage/current protection to loosest settings.
Load Line calibration will likely need to be adjusted
cTDP of 450w, PBO on Enabled, Multiplier on ~355 were the best results in our case. While the VRMs were quite toasty past 325w, the CPU stayed around 68, thanks to the TR4 II cooler from Enermax.

We will do the disk array stuff as its own video because this video was already running looooooong as it was.

Big thanks to our Patrons and Gigabyte for making this project possible.

AMD's PERFECT Response to Turing!
The Good Old Gamer
Published on Sep 20, 2018
AMD's been DEAD Silent all year on the GPU front (aside from Vega 20,) but is this FEAR? Or a more tactical strategy?

 

RUMOR: AMD Radeon Polaris 30 GPU Based On 12nm FinFET Node Gearing Up For Launch:

https://wccftech.com/amd-radeon-polaris-30-gpu-family/

One thing though, 12nm FinFET node... is it TSMC node or GLOFO node?
If its TSMC and this GPU is actually being made, I'm expecting Polaris 30 to be clocked FAR higher at much lower power draw (probably still a bit higher if AMD overvolts the GPU's from factory as usual).
TSMC process = designed for high clocks and efficiency.
Glofo -process = designed for low clocks and mobile parts.

If its the 12nmLP node from GLOFO, then 15% performance increase sounds plausible... but, if Ryzen + is any indication, it might actually result in same or higher power draw.

Posted on September 24, 2018
https://azure.microsoft.com/en-us/blog/introducing-the-new-hb-and-hc-azure-vm-sizes-for-hpc/

"We are excited to announce two additions to our H-series Azure virtual machines for High-Performance Computing (HPC). The new H-series VMs are designed to deliver leadership-class performance, MPI scalability, and cost efficiency for a variety of real-world HPC workloads.

First, we are introducing HB-series VMs optimized for applications driven by memory bandwidth, such as fluid dynamics, explicit finite element analysis, and weather modeling. HB VMs feature 60 AMD EPYC 7551 processor cores, 4 GB of RAM per CPU core, and no hyperthreading.

The AMD EPYC platform provides more than 260 GB/sec of memory bandwidth, which is 33 percent faster than x86 alternatives and 2.5x faster than what most HPC customers have in their datacenters today."

 

AMD spills the beans on future Arcturus graphics cards

https://www.techradar.com/news/amd-spills-the-beans-on-future-arcturus-graphics-cards

And from Wccftech:

AMD Next Generation Arcturus GPU To Succeed Navi GPU – New Radeon Family Naming Scheme Also To Be Introduced After Navi

https://wccftech.com/amd-arcturus-7nm-next-gen-gpu-revealed/

But, I wonder, if Navi is due to be released next year (2019), then when is this supposed Arcturs due?
And will Arcturus be on 7nm+ (seems like the article is pointing there it would seem).

Also, I disagree that AMD needs to step it up so they can take on Nvidia Turing.
They need to apply the same strategy like they did with Intel... imagine what Nvidia COULD do (take into account potential process and architectural changes), and build a new GPU architecture (Arcturus?) based on THAT and a proper manuf. process designed for high clocks and efficiency.

7nm Navi could get them far and probably exceed Turing if they do it right (basically, rival Turing on 7nm - minus the tensor cores obviously - unless AMD can repurpose existing compute hardware towards AI - and since Vega is made for AI, might that give us some indication that they are doing this?).
They do have the benefit of making Navi on a high performing process for a change... but they need to work a bit on dropping voltage from factory...

Also, it depends on what architecture is Navi based on and what kind of changes will it bring.
Are we talking about modified Polaris, modified Vega or something else?

 

One thing nags at me.
Vega and Polaris are both clocked roughly 30% lower than NV equivalent GPU's... now, a major part behind this is the 14nmLPP node from GLOFO which was designed for low clocks and mobile parts... and in spite of this, both vega and Polaris manage to produce similar, same or better performance despite being clocked lower than NV counterparts.

Now, if AMD at the time had access to 16nm TSMC... it is possible it could clock the GPU's on the core (and likely on VRAM) higher... comparable to Pascal levels.
At this point, it is conceivable that they would easily smash through NV's Pascal lineup at same or slightly higher power draw (if they continued to ship them with high voltages from factory).
Not sure about V64 being then on par with 1080ti since 1080ti DOES have more hardware relevant to games (such as more ROP's, texture units, etc.), but I also partly doubt it couldn't seeing how V64 LC runs at about 1600MhZ... which puts it almost/roughly between 1080 and 1080ti.
So, at the very least, with brute force clocks taken into equation... could V64 get to same/similar levels of 1080ti?
We know that HBM was a bottleneck due to lower clocks... so its conceivable that it would have been able to run much higher (say 1100 to 1200 MhZ?) and lets say 1600MhZ core... might actually get V64 on par with 1080ti.

Now, 7nm TSMC is a fundamental polar opposite process of glofo 14nm and, its a direct improvement on 16nm and 12nm TSMC processes.
So, I'm actually thinking that Vega, Polaris and/or Navi, if properly executed on 7nm TSMC should technically be able to RIVAL or even surpass 7nm NV offerings (minus the tensor cores - and again, maybe AMD is working on an open source alternative that can use their compute power).

This could also depend on AMD not shipping Navi or Vega on 7nm at 1.2V from factory (which can make or break first impressions).
Most people don't really take into account this about AMD gpu's and how AMD is less strict on voltage modifications vs Nvidia.
To that end, AMD should indeed step up their game on GPU's end.
Now that the node won't be a bottleneck anymore, I do expect of them to be able to rival NV upcoming offerings on 7nm (not 12nm).

So, I don't understand why are people underestimating process node differences so much (which as we saw in the past can make or break a product)?

AMD Adds Dynamic Mode for Threadripper, Two New Chips Coming In October
by Paul Alcorn October 5, 2018 at 12:17 PM
https://www.tomshardware.com/news/amd-cpu-threadripper-2970wx-2920x,37895.html

"AMD announced that its Ryzen Threadripper 2970WX and 2920X processors would be available on October 29, 2018 for $1,299 and $649, respectively. The company also announced several new advances on the software front, including a new Dynamic Local Mode that automatically migrates applications to CPU cores with direct memory access.

The two new Threadripper processors, which AMD announced earlier this year, offer a less-expensive path onto the X399 platform. The range-topping Threadripper 2990WX introduced the first 32-core, 64-thread processor to the high-end desktop. The impressive processor boasts a 3.0GHz base frequency that stretches up to 4.2GHz, but it also comes with an eye-watering $1,799 price tag.

The more accessible $1,299 Threadripper 2970WX slots in with 24-core and 48-threads and features 3.0/4.2GHz base/boost clocks. Fewer cores equate to less raw horsepower in heavily threaded workloads, but like all of AMD's Ryzen processors, the 2970WX comes with an unlocked multiplier, so overclocking is on the table. The 2970WX also features the same 64MB of L3 cache as its more expensive counterpart. That's generous on AMD’s part: Intel typically disables cache in lock-step with cores, so “lesser” chips come with less cache.

AMD’s WX processors feature a unique architecture that causes poor performance in a few common desktop applications. As we’ll cover shortly, AMD also revealed a new software feature today that helps address the performance challenges born of the multi-chip design.

The new $649 Threadripper 2920X slots in beneath the 16 core, 32 thread 2950X. The 12 core, 24 thread 2920X offers a base frequency of 3.5GHz and a maximum boost clock rate of 4.3GHz. As with previous X-series models, the 2920X utilizes a pair of eight-core dies and two dummy packages. The active dies expose the same 32MB of L3 cache as the more expensive 2950X.

***ThreadRipper Dynamic mode details / images on Tom's site, and on AMD's site***

Finally, the company also announced a few updates to the broader software ecosystem:

• Game performance using Nvidia Graphics products on Ryzen Threadripper platforms has reportedly been improved. See page 13 of the 399.24 driver release notes for more information.
• The Far Cry 5 Update 9, released on August 9, addressed an application bug affecting many logical processor (high thread count) products, including Ryzen Threadripper 2990WX, and claim to improve gaming performance. You can read more details here.
• Microsoft released the Windows 10 October 2018 update (version 1809) on October 2. In addition to a number of new features, the update is said to improve stability with products leveraging 64 or more logical processors (high thread count processors), including Ryzen Threadripper 2990WX."

Dynamic Local Mode available starting October 29th
Beginning October 29th, Dynamic Local Mode will be a new package included with the latest version of AMD Ryzen™ Master. Downloading AMD Ryzen™ Master on or after the afternoon of 10/29 will automatically configure Dynamic Local Mode on your system if it contains an AMD Ryzen™ Threadripper 2990WX or 2970WX processor (also available starting 10/29). Looking further ahead, AMD also plans to open the feature up to even more users by including Dynamic Local Mode as a default package in the AMD Chipset Drivers. Let the countdown begin! We’re looking forward to your feedback.

A Look At Linux Application Scaling Up To 128 Threads
Written by Michael Larabel in Processors on 10 October 2018
https://www.phoronix.com/scan.php?page=article&item=linux-128-threads&num=1

"Arriving last week in our Linux benchmarking lab was a dual EPYC server -- this Dell PowerEdge R7425 is a beast of a system with two AMD EPYC 7601 processors yielding a combined 64 cores / 128 threads, 512GB of RAM (16 x 32GB DDR4), and 20 x 500GB Samsung 860 EVO SSDs. There will be many interesting benchmarks from this server in the days and weeks ahead.

For some initial measurements during the first few days of stress testing this 2U rack server, here is a look at how well various benchmarks/applications are scaling from two to 128 threads.

This article with these benchmarks is mainly intended for reference purposes for those curious how well different Linux workloads scale up to 128 threads with these multi-core benchmarks available via the Phoronix Test Suite and OpenBenchmarking.org. Tests were done with 2, 4, 8, 16, 32, and 64 cores enabled and then the default configuration of 64 threads plus SMT to yield 128 threads of jaw-dropping power.

During this testing, the benchmarks were running off an 18 x RAID10 array of these Samsung 860 SSDs to ensure there was no I/O bottleneck in any of these real-world or synthetic benchmarks, most of which are open-source. Ubuntu 18.04 LTS was running on this PowerEdge R7425 while having upgraded to the Linux 4.19-rc6 kernel.

Again, these are just some initial measurements while during the initial "burn-in" period of the server but figured plenty of readers would be curious how these different workloads are scaling up to 128 threads so here are these results for reference or for assisting in your own multi-core performance testing.

In the days ahead will also be some interesting container density benchmarking via a new addition to the Phoronix Test Suite for those interested in containers/Docker performance, among other interesting benchmarks."

For several pages of details benchmark graphed results continue at the article hosting site:
https://www.phoronix.com/scan.php?page=article&item=linux-128-threads&num=2

"Those wishing to dig through even more benchmark results can find this larger set of multi-threaded benchmark results from this AMD EPYC 7601 server via this OpenBenchmarking.org result file. Stay tuned for a lot more dual AMD EPYC 7601 benchmarks coming up soon on Phoronix -- any other non-standard test requests can be submitted via Twitter or the forums as I am certainly excited to throw as many interesting benchmark-friendly workloads as possible on this box. Or want to see how your own Linux system(s) performance would compare to these varying amounts of EPYC CPU cores? Simply install the Phoronix Test Suite and run phoronix-test-suite benchmark 1810109-SK-DUALAMDEP26."

Cray Is Back to Selling AMD-Powered Supercomputers
Michael Feldman | October 17, 2018 13:00 CEST
https://www.top500.org/news/cray-is-back-to-selling-amd-powered-supercomputers/

"Cray announced it has sold a CS500 cluster powered by AMD EPYC processors to the Hass F1 Team, which will use the system to run aerodynamic simulations for its Formula One racecars."

"“Every year we’re tasked with building the fastest and most efficient racecar in the most technologically advanced racing series in the world,” said Gary Foote, Chief Information Officer, Haas F1 Team. “We’re pleased to partner with Cray and utilize their HPC solutions. The double precision computing power of our new system will help solve our most demanding CFD and data challenges.”

Of course, if double precision capacity was the only factor, the Hass team might well have gone with an Intel Xeon chips, which can generally outrun EPYC processors in floating point performance. In truth though, Formula One sporting regulations limits computation fluid dynamics (CFD) performance used for wind tunnel simulation to 25 teraflops, so squeezing the best price-performance from these systems would appear to be much more of a driving factor.

In addition, the EPYC chips have demonstrated a particular affinity for CFD codes, which demand lots of memory bandwidth. As we pointed out in April when Cray announced it had added the AMD option to its CS500 line, independent testing showed that EPYC machinery ran CFD software significantly faster than its Xeon competition. That’s mainly because the EPYC chip has eight memory channels, compared to the six available on the latest Xeon “Skylake” CPUs.

Like other Formula One setups, the Hass F1 team will use the system to run wind tunnel simulations so that it can study the airflow patterns around its vehicles, enabling engineers to optimize their designs for better aerodynamics. In the Formula One business, less drag and more downforce are critical to building winning racecars.

Although most, if not all, Formula One engineers use HPC clusters nowadays to help design their racecars, few openly share information about their systems due to the intense competition between teams. The new Cray system is no exception. The supercomputer-maker didn’t offer much in the way of details on the Haas F1 cluster, other than its use of AMD’s EPYC 7000 processors and being paired with a Cray ClusterStor L300 storage system.

The system is scheduled for delivery in December 2018, in time for the 2019 racing season."

AMD 7nm Navi GPU Allegedly Shows Impressive Performance In Lab For 2H 2019 Launch
https://hothardware.com/news/amd-7nm-navi-gpu-allegedly-impressive-performance-lab

Will be interesting to see just what kind of performance it demonstrates.
These news are encouraging though because before, AMD was almost always very quiet about their upcoming gpu's right until they were released.
This is indicative of what happened with Ryzen - AMD was happy to report it exceeded their expectations.
It's possible they had a similar hit with Navi either because the managed to optimise the architecture, or/and because the node bottlenecks that existed with GLOFO nodes are no longer present.

 

While it's fun to speculate, it seems that AMD is aiming for cost / performance in the mid-range, and doesn't intend to compete at the high end of the GPU market.

Most of the cards sold are mid to low range so that's where the bulk of the sales should be for AMD, and Nvidia.

The market seems to be moved by perception from the high end card performance, which is silly because they aren't buying those high end cards anyway, but there it is - Nvidia gets the mind share.

Hopefully the Ryzen continued success will push forward awareness of the new AMD mid-range performance Polaris, Vega, Navi, Arcturus GPU's as they arrive.

People also like to match their hardware, so AMD coming out with a solution for both CPU and GPU helps move both to some extent.

Maybe down the road the multiple GPU support in games will arrive with wide support, and AMD can try putting 2-4+ mid-range GPU's per card again.
