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

It might be best to wait for the other shoes to drop, when AMD does the next round of releases later this year...

Why throw good money after bad (x299) on an expired technology, when AMD will crank out new Zen generational CPU's like clockwork.

Save up for the good stuff coming next from AMD instead. Today's AM4 / sTR4 will discount as new technology is released, either save money on the stuff you want now then, or get the new stuff.

 

for 16 core 99% of use can live with dual channel. There are times quad channel is required. So I can see the point of a TR over the 3950x.

 

Blower cooler, so it was a reference model. Price ending in .96 means it was open box and being marked down so significantly means it had probably been sitting on the shelf for months. The RTX 2080 I bought a while back was marked the same way. No reaction to "panic" here, just a retail outlet doing what retail outlets do in order to move old inventory. Dude got a great deal, and I hope it works for him, but let's not read more into it than what likely actually happened.

 

That all was clear from my text and the "Clearance" listing on the receipt, no surprises there. If you had gone to the link I gave for his reddit posting, you would have also heard it from him:

haahaahaa 6 hours ago
"Yeah, I meant to put open box in the title. Not sure when this card was $299 new, but that's the list price with the open box discount taking it to $240."

My point wasn't to look for "driver panic" sales - that's what I named it - I certainly didn't expect retailers to name it that nor did I expect anyone would think that from what I wrote. And, given the driver problems where inexperienced owners give up and return the GPU, Open Box sales are a great way to benefit from the situation.

My point was that now is a good time to look for sales because the sales have likely decreased for the RX 5700 / RX 5700xt during the driver problems, but now that it looks like AMD is beginning to get a handle on the fixes, the prices will likely start going up again - discounts end.

When sales volume picks back up again the sellers won't have to offer discounts any longer, it might already be happening:

ASRock AMD Radeon RX 5700 XT Is Seriously Cheap at $360
By Jeremy Laird 10 days ago
$50 off and just possibly the cheapest new 5700 XT available today
https://www.tomshardware.com/news/Asrock-AMD-Radeon-RX-5700-XT-deal

That discount is now down to $30 right now:
https://www.newegg.com/asrock-radeon-rx-5700-xt-rx-5700-xt-challenger-d-8g-oc/p/N82E16814930020

That's the twin fan model, the good news is that the 3 fan model is $50 off:
https://www.newegg.com/asrock-radeon-rx-5700-xt-rx-5700-xt-taichi-x-8g-oc/p/N82E16814930022

Usually sales happen and the throng of people clear them out before you can get to them - it still might happen with these sales - but now that fewer people are looking due to being distracted by the transient situation of driver problems, now's the time to shop.

After a few weeks and months of declining sales the discounts come out, when the problem is resolved and people start buying the RX5700 / RX5700xt GPU's again, there'll be no need for discounts.

If you didn't get that from what I was saying before, then I'm happy to clarify it for you now.

Here's another 5700xt blower at Microcenter, and it doesn't say it's an open box sale, but it is already sold out. It might be worth a call to your local store to ask if they are going to restock it or if there are any other 5700xt / 5700's on discount - open box or not:

Sapphire Technology Radeon RX 5700 XT Single-Fan 8GB GDDR6 PCIe Video Card
$319.98 SAVE $64.00 $255.98
https://www.microcenter.com/product...-5700-xt-single-fan-8gb-gddr6-pcie-video-card

It might already be too late to catch the best "driver panic" discounts, but it's still worth a try...

 

And who says TRX40 also isn't EOL after Zen 3? Wouldn't that fit your good after bad statement?

Two years on TR, after all.

 

But, people are still buying TR1/TR2 at great price discounts after TR3 has released, and the same goes for ThreadRipper 3 CPU's and motherboards that will be available at a discount when ThreadRipper 4 comes out.

Maybe the next generation Zen CPU's on AM4 will also bump up the throughput against the current best 3900 / 3950x? That might reduce sales on the ThreadRipper 3 and cause them to discount pricing after the next generation AM4's are released.

Maybe AMD will release the TRX80 model with new CPU's that have even higher memory size and throughput, and draw a bunch of sales from the TR3 camp - reducing demand and therefore prices again.

Given we haven't heard anything about TRX80 / WRX80 maybe AMD is holding back that memory bandwidth increase for the next generation ThreadRipper 4 - who knows?

In any case, as long as you can get the sparkle out of your eye's from the latest generation Threadripper, good deals can be had on the TR1/TR2 generations - save money and get the performance you wanted back when they weren't affordable.

And, the same goes for TR3 when TR4 comes out, I'm sure it will be a similar situation. TR4 will be expensive, and TR3 discounts will make them price competitive. So if you can remember that you wanted TR3 when it wasn't affordable to you, and that level of performance is still enough for you - the price discounts should be worth the wait?

I guess if TR4 is way better and not much more expensive it might be hard to pull the trigger on something you can afford vs dreaming about something that's much faster that you can't afford.

Of course you could always wait for TR5 to come out and then you could by TR4 cheap! Then again TR5 will be even faster again...

Just buy what you can afford when you need it, and if it works for your needs right then it's worth it.

Be happy with what you have, that's the only thing you've got.

 

At this point until TR4 and/or TR5 are out I will not trust any statement on compatibility. That boat has sailed for AMD. TRX80 and WRX80 are pipe dreams at best right now too. Because of how AMD treated the enthusiasts with x399 people are very Leary to sink any faith in TR, AMD or TRX40 and rightfully so.

 

Maybe AMD should try what Samsung does with their drivers...

https://www.samsung.com/semiconductor/minisite/ssd/notice-nvme-driver/

 

There is always the waiting game and people could always save for what is next. The used x299/x399 stuff is at their value point right now. X299 would be faster than X399, especially with audio transcoding. I know you're biased against x299 or any other intel platform, but 12-16 cores at 5GHz is no slouch, regardless of what you want to believe. Sure it's not as fast in SOME workloads as a 24-36 core TR3 setup, but for the majority of my tasks it's going to be as fast.

You go on to say "Just buy what you can afford when you need it, and if it works for your needs right then it's worth it." Exactly, this is where x299 and x399 are right now. It's just a shame that AMD doesn't want to release a more affordable TR3 processor.

 

Yup, buy what you need when you need it, but you do need to consider what you are buying

Noone needs to buy an Intel CPU with all the security patches and future problems, it's a known bad situation that I can't imagine anyone desiring to acquire.

I dislike Intel CPU's for a rational reason, I dislike Intel for their poor stewardship of technology, Intel has squandered their power and place and let down everyone with their results.

That was before we found out that Intel's CPU's are poorly designed and have a crap bag full of failures all wrapped up into an overheating overpriced mess.

People that depended on Intel time after time have been let down and those buyers are not happy to continue using Intel and are looking for alternatives.

It's a great time for AMD + other CPU designers to make their mark in the giant hole Intel has opened for them.

If you want to ignore all of that I don't understand, but then again people do a lot of things I don't understand. It's like they can ignore the obvious failures and allow the sparkling marketing to sell them anyway.

Nvidia is worse, they could have made the 2xxx GPU's into better and faster GPU's for gaming and other work and built dedicated AI hardware, each for their own work.

Instead Nvidia used their marketing power over people to ram RTX / DLSS half-baked down their throats, wasting 50% of the silicon on circuits that don't get used in more than a few games - and even then most people will turn RTX / DLSS off to get better FPS at the resolution they want to run.

4k gaming was likely right there in the real estate made available by that silicon, and Nvidia squandered their opportunity, leaving us all down and yet still expecting us to spend far more money than the performance delivers.

Simple, obvious things that people are completely mind-fogged over, and actually fight to defend those company's mistakes.

Even if there are no good alternatives, buying those things - to me - is a waste of money and encouraging their bad behavior. It's good money after bad.

Instead I'd get a part-time "lawn mowing" job to earn the extra to get the ThreadRipper 3 and avoid getting stuck with the x299 solution.

Anyway, I hope you enjoy your x299.

 

I agree, shame on Intel for not having any innovation. Also shame on AMD for taking so long to actually be competitive and push Intel to actually get off their rear ends. This is why I'm not a fanboy. Blindly supporting any company leads to stagnation as we've had with Intel. You can check my sig and realize I'm not a fanboy...

And shame on NVIDIA for taking a chance with something. We all know nothing ventured nothing gained. Now that AMD is somewhat catching up in the mid end, I bet NVIDIA comes out with something that is a reasonable step up. Having said that, if you want the fastest thing, NVIDIA is still the way to go...

X399 is just a dead end platform as x299, you'll have to admit that. And the security stuff is semi-important to me. It's like browsing the internet without virus protection (something I do because I watch where I go). It's not something that's going to entirely sway me, there are other things that I value as much/more.

Sadly working 70-80 hours a week as a resident physician doesn't lead to much time to mow lawns, lol.

 

Yeah, making excuses for Intel and Nvidia, boo-hoo

AMD TR1 / TR2 earned their stripes, progressing AMD and leaving perfectly useful secure CPU's for price sensitive uses. It is still current technology to me, being sold as new and simply filling performance slots and needs that the ThreadRipper 3 can't accomodate.

I figured you'd not be a "lawn mower", I was simply suggesting taking on some extra work to carry the purchase, or wait a little longer to save up what is needed - keeping an eye out for sales or new opportunities when they arrive.

Fortunately I never even thought to use credit for personal purchases, so I have no debt. So I'd never suggest that to someone as a method to attain their goals.

Not knowing what kind of doctoring line you are in, that's the best I can suggest, I would hope you could find additional sources for income in your line if you gave it some thought.

Then you could donate some time to assuage your guilt for being all about the money for a goal.

Good luck

 

TR1/TR2 are may be current tech but not state of the art tech. With the prices of TR and plus EOL x399 people do not want to invest in them except at severe discounts, like used pricing etc.. Even where Ryzen 3xxx is concerned and they are mostly compliant with 1st and 2nd gen boards but at least you can buy the old gen and upgrade to 3rd gen.

Edit; amazon has the 3960x back but only 3 left. Like I said hot cakes and it is the 3rd gen entry. A 3960x as a new system is probably better than any 1950x, 2950x, 2970x or even 2990x option.

 

Amazon Statistics shows a different preference order, the 3960x isn't #1 in any of them. The 3960x is not the most desired ThreadRipper.

The 3960x is way behind a lot of other 1st and 2nd gen and 3rd gen ThreadRippers, it's #52 in Most Wished for, behind the #27 1920x, #29 3970x, #30 3990x, #35 2950x, #50 2920x.

So it's not due to not enough in stock... there are 5 other 1st/2nd/3rd gen ThreadRippers more desired than the 3960x.

As far as the older gen offerings the results are compiled from some data that existed before the 3rd gen TR's were marketed so the results will be skewed. The 3960 mostly has been snapped up by price gougers but people wil not pay a premium so close to 39770x prices, they would just buy a 3970x.

Strange that the 3960x isn't on the wish list higher up too...if the 3960x was in demand and out of stock it's position in the wish list should be a lot higher.

AMD has a lot of headroom for cost cutting, that's good news

AMD Gives Itself Massive Cost-cutting Headroom with the Chiplet Design
by btarunr Wednesday, 22:52 Discuss (87 Comments)
https://www.techpowerup.com/264271/...cost-cutting-headroom-with-the-chiplet-design

At its 2020 IEEE ISSCC keynote, AMD presented two slides that detail the extent of cost savings yielded by its bold decision to embrace the MCM (multi-chip module) approach to not just its enterprise and HEDT processors, but also its mainstream desktop ones.

By confining only those components that tangibly benefit from cutting-edge silicon fabrication processes, namely the CPU cores, while letting other components sit on relatively inexpensive 12 nm, AMD is able to maximize its 7 nm foundry allocation, by making it produce small 8-core CCDs (CPU complex dies), which add up to AMD's target core-counts.

With this approach, AMD is able to cram up to 16 cores onto its AM4 desktop socket using two chiplets, and up to 64 cores using eight chiplets on its SP3r3 and sTRX4 sockets.

In the slides below, AMD compares the cost of its current 7 nm + 12 nm MCM approach to a hypothetical monolithic die it would have had to build on 7 nm (including the I/O components).

The slides suggest that the cost of a single-chiplet "Matisse" MCM (eg: Ryzen 7 3700X) is about 40% less than that of the double-chiplet "Matisse" (eg: Ryzen 9 3950X). Had AMD opted to build a monolithic 7 nm die that had 8 cores and all the I/O components of the I/O die, such a die would cost roughly 50% more than the current 1x CCD + IOD solution. On the other hand, a monolithic 7 nm die with 16 cores and I/O components would cost 125% more. AMD hence enjoys a massive headroom for cost-cutting.

Prices of the flagship 3950X can be close to halved (from its current $749 MSRP), and AMD can turn up the heat on Intel's upcoming Core i9-10900K by significantly lowering price of its 12-core 3900X from its current $499 MSRP. The company will also enjoy more price-cutting headroom for its 6-core Ryzen 5 SKUs than it did with previous-generation Ryzen 5 parts based on monolithic dies.

Good news, TSMC unfazed by Coronavirus shutdowns...

Coronavirus outbreak impacts: TSMC unfazed by outbreak
DIGITIMES staff, Tuesday 11 February 2020
https://www.digitimes.com/news/a20200211VL200.html

"The coronavirus outbreak in China is hitting hard many in the supply, but TSMC is a major exception.

The world's top pure-play foundry has no plans to revise its sales guidance for the first-quarter, and reportedly none of its major clients are cutting orders despite the epidemic, with the foundry's capacity supply remaining tight.

While even TSMC's China fabs have been able to maintain smooth operation, others in the IT sector have difficulties returning to normal production though work at their China plants has resumed.

Foxconn and Pegatron, like many other Taiwan-based makers running manufacturing plants in China, are seeing limited numbers of employees returning to work. Failure to resume full production at Foxconn and Pegatron will affect iPhone shipments to Apple.

TSMC continues to see supply run tight despite coronavirus outbreak: TSMC continues to see its supply remain tight, with no cutbacks in orders from its major fabless clients such as Huawei's HiSilicon, according to sources familiar with the matter.

Uncertainties in employee returns may disrupt Foxconn production: Uncertainties in employee returns due to the coronavirus outbreak have become a challenge for Foxconn Electronics, a key Apple supplier with assembly facilities in Chinese cities of Zhengzhou, Shenzhen and Taiyuan, according to industry sources.

Pegatron hit by low labor return rates: With China locking down Shanghai to prevent the spread of the coronavirus, Pegatron's plant in the city only saw a limited number of workers return to their posts on February 10, the first working day after the extended Lunar New Year break, according to sources from the upstream supply chain."

 

Yes compiled daily from data dating back to when, if data is from the year well?

 

Amazon does this to inform us as to what are the most popular - right now, not months ago.

Not to mention that the fact that the 3960x has dropped that far down the popularity list of ThreadRipper CPU's shows the lists are only expressing the relevant wishes, sales, and Hot Products, not "old data from a year ago".

The data is updated on a cycle advertised in the title, and the currently less popular choices get pushed down into the stack and off the board at their #cutoff, likely chosen to only show currently relevant entries.

Amazon has their own interest in mind to keep these lists relevant to buyers and sellers. And, Amazon sells almost everything these days, so old hardware can be popular given large purchases from companies refreshing or expanding. That's why you see older items jump up near the top of the list briefly, some are timeless reliable choices that have demand as well. Like the 1900x, 1920x, 1950x, etc.

Sorry, show me the data collection or at least the collection policy to prove its validity, otherwise it is just a best guess at best. Also it i just one etailer. do you have NOTHING to back your claims. No one else here will back up your obviously weak statements I just donot know what cloud you head is burried in, wait is it a company called AMD getting your nose all brown?

Edit I mean come on, no one can keep the 3960x in stock, ( the most problematic of the TR's), and the only one right now getting price gouged. How much more obvious do you need? Are you going to argue next you no longer need to breath air or drink water as you have found other ways to consume them?

 

Have you heard yet? The Threadripper 3990x is amazing...

AMD Threadripper 3990X Scores Another Win: We Test New SPECWorkstation 3 Update
Calling all speedfreaks
By Paul Alcorn 2 days ago
https://www.tomshardware.com/features/amd_threadripper_3990x-spec-workstation_3-performance-update

"The SPECwpc subcommittee has announced a new version of the SPECworkstation 3 benchmark for workstations to accommodate processors with more than 64 threads.

That move certainly benefits the only workstation-class x86 processor with more than 64 threads in a single socket: AMD's monstrous 64-core 128-thread Threadripper 3990X. We decided to put the new release to the test to see the full threaded might of the 3990X in action, and the results are impressive.

Upsetting the semiconductor industry is hard, particularly when you're fighting an entrenched and much-larger rival, and sometimes things get broken when you're redefining an industry.

In AMD's case, those broken things consist of operating systems and applications that weren't tuned to extract the full performance of its fledgling first-gen Zen architecture, let alone the core-heavy designs of Zen 2.

The 64-core 128-thread Threadripper 3990X is the best example because it more than doubles the number of cores available with Intel's halo workstation parts and sets an entirely new bar for single-socket systems.

Windows 10 splits cores up into 'processor groups' of 64 threads apiece, so some applications and benchmarks that aren't tuned to span across the groups don't benefit from the increased thread count..."

Just in case someone forgot to do their RMA, the time is running out...

PSA: If you bought a Ryzen 1000 series CPU at launch, test it for the segfault bug before the warranty expires this month
r/Amd Posted by u/chithanh 15 hours ago
https://www.reddit.com/r/Amd/comments/fblhta/psa_if_you_bought_a_ryzen_1000_series_cpu_at/

"If you bought a Ryzen 1000 at launch in March 2017, the 3-year warranty which AMD provides for boxed CPUs is almost up. Many of the Ryzen 1000 produced before week 33 in 2017 are affected by the segfault bug which manifests primarily in Linux when compiling software, but reportedly also during certain other tasks such as XML processing.

Testing for the segfault issue can be done through the kill-ryzen.sh script from GitHub. This script will run under Linux natively, and also under Windows with WSL or inside a Linux VM.

One thing to note, Ryzen CPUs that people got back from segfault RMAs appear to be much better overclockers than what they originally had. So it might be a good idea to RMA even if you do not normally use Linux."

Another gem from Level1Techs, this time on the 3990x...he covers his in depth work with the 3990x on Linux / Windows seeing what optimizations can be used to improve "scores" and performance - he refers to a patch by Linus (Torvalds) to Linux I posted a while back that reduced the number of context switches by an order of magnitude which really improves performance with high core count CPU's like the 3990x.

AMD: 3990X And The Unbenchmarkable
Feb 17, 2020
Level1Techs
3990x Article: https://www.level1techs.com/article/t...

 

To those looking to build a new TR system. Why would anyone look to a new system below the 3960x. In CB15 it out performs a 2990x outright and no EOL x399. TBH if the fanboy in me still existed as the 3970x is available at a slight discount I would have a 3970x to replace the 1950x right now.

https://www.kitguru.net/components/cpu/luke-hill/amd-ryzen-threadripper-3960x-3970x-cpu-review/5/

 

well you only need do with a 3960x to kill all gen 2. As far as 1400 to 500 you have to talk overall system cost. When we are talking about going this high end the cost difference is not that high. I have a 1950x as fast as any 2950x. I do not need a upgrade at all, just wanted one before but no longer. Again used deals are another story.

Edit; Amazon has 680 for the 2950x so some etailers are realizing they need to discount them.

 

Interestingly even though Amazon is sold out of 3960x's, it isn't on the "best seller" list anymore. So they got stock and it actually sold less, lol. I'm going to chalk that up as an unreliable source. Having said that, B&H and others still have some stock. Hard to spend more than double on both the board and the CPU just to go with a 3960x though...

 

As far as if you are going TR, it is not too hard. Now a super discounted overall 2950x where that is all you will ever need before retiring it, ok. problem there is most people do not plan on early system retirements.

I just have to add en edit; If they left x399 compliance in that $500 x2950 now would be a killer deal dropping in a 3960x a couple of years down the line in.

 

Some musings from Adored on upcoming Big Navi. Based on his extrapolations, should see it competing with 3000 series from NV. (50% faster than 2080Ti) I also gather this was recorded before 20.2.2 was released since he's still ranting about fixing drivers.

 

Micro Center has the best deal on a 3970x and main board. just do no need it. I have used the 1950x once in the last month, my family uses it more.

On another note: 20.2.2 got updated with WHQL and some other last minute updates dated March 5.

 

AMD Clarifies Comments on 7nm / 7nm+ for Future Products: EUV Not Specified anandtech.com | Today

As part of AMD’s Financial Analyst Day 2020, the company gave the latest updates for its CPU and GPU roadmap. A lot of this we have seen before, with the company talking out to Zen 4 and Genoa on its datacenter CPU product line, out to Zen 3 and Ryzen 4000 with the consumer product line, and now with the RDNA/CDNA split between consumer and compute graphics. In previous graphs of a similar nature, AMD used the term ‘7nm+’ when referring to products beyond the first iteration of 7nm. AMD has today clarified to us that this does not mean they are using TSMC’s N7+ process node for those items.

TSMC has three high-level versions of its 7nm process:


Because AMD labeled those as 7nm+, when TSMC called its version of 7nm with EUV to be N7+, one of the obvious assumptions that people have made is that where AMD wrote 7nm+, it was to be on the N7+ process. We have since learned that this is not entirely correct.

In order to avoid confusion Better say promised too much, AMD is dropping the ‘+’ from its roadmaps. In speaking with AMD, the company confirmed that its next generations of 7nm products are likely to use process enhancements and the best high-performance libraries for the target market, however it is not explicity stating whether this would be N7P or N7+, just that it will be ‘better’ than the base N7 used in its first 7nm line.

 

AMD not other GPU's

Wow, almost, but still not, as bad as Intel's new vulnerability eighth CSME...

Yeah, new arch didn't save AMD on this one. And we haven't seen the last vulnerability from neither Intel or AMD. More will come.

 

Oh, no doubt this is bad. It is similar to Intel's portsmash with the L1 and memory security vulnerability. Not trying to belittle this. I called Intel out for that one when discovered awhile ago. It is bad.

But, Intel's one disclosed today is a vulnerability in the converged security and management engine, which basically can subvert all DRM, makes encryption nothing, and is an unfixable vulnerability. In fact, you need to apply the patch immediately to remove the exploit over the network for this to reduce it to physical access and hope someone never gets physical address.

It can rewrite ROM and decode the system key on Intel machines before boot on power up. This vulnerability for Intel is bad.

So not trying to belittle AMDs vulnerability, which is similar to that of Intel's announced either last fall or the fall before that (seriously, been two years of almost weekly Intel vulnerabilities and they keep coming). Just it is a shame security is currently in such a shape...

going through @hmscott withdrawal, no new posts

 

I hope he's doing well, even if I am enjoying the relative quiet.

 

All this 'tantrum' over a 'vulnerability' which leaks relatively useless meta-data and not anything of particular value.

Curious how Zen uArch remains LEAST affected platform in regards to security exploits, whereas new exploits are found for Intel on an almost daily basis (including one that apparently cannot even be repaired).

Also, correct me if I'm wrong, but a LOT (aka, most) security vulnerabilities that affect Intel have been found to simply not execute on AMD cpu's (which makes Zen FAR more secure by default).

 

It would not be good FUD unless they blew up the severity of the issue. You have to look at the money backing it all.

 

Let's just say the quiet will be sticking around for a very long time.

 

something happened to @hmscott ?

 

Illustration below;

 

My interest in this vulnerability is the potential for figuring out potential info stored in secure memory. Sure, Metadata may seem benign, and compared to many Intel exploits it is benign, but figuring out where something is on memory to try to target bit flips through rowhammers, that is where I would try to take this.

Now, as I said before, I'd have talked about this before, but the Intel CSME vulnerability had just dropped and was way worse, as is this new one dropping the least day or so.

Comparatively, AMD is way safer. Doesn't mean we should not give all vulnerabilities the respect they deserve.

Also, AMD market share is way smaller. Less base, less research since you focus for maximum impact. Same with windows over mac or linux. Viruses still exist on other platforms, and looks like a huge uptick on mac recently.

We also haven't heard which may effect arm CPUs recently. Just saying and giving context.

Guess I lost my reason for reading this forum. At least his posts were informative and entertaining.

 

HMScott was banned after far too many warnings, he couldn't grasp the concept of playing well with others. Sometimes he had some good postings and was helpful to members, but other times it was just posting links to various youtube videos or fighting with members. This will be the last on that discussion, if you have concerns you can PM me or the other mods.

Lets get this thread back on track.

I still don't know why Microcenter can't get any 3960x in stock...

 

Personally, I'm more interested in zen 4. They mentioned, for server chips, an interposer, hbm, 10x bandwidth. Don't know what they mean by that but likely pcie 5.0, 500GB to 1TBps memory throughput, etc.

But that is a ways away.

If you can wait for Q3 or Q4, Zen 3 gets rid of CCXs, which will help latency and performance.
