Mobile Polaris Discussion

Good find! So, that's what the card is gonna look like then, I'll study the pic & see if it would be compatible with my heatsink. I'm gonna wait till it's available on ebay or something, not gonna try & buy it from a random Chinese site! If you're gonna buy it & try it @Raidriar then I'd be interested to know how you get on with putting it in your M18xR1 - as it's the same generation & similar to my M17xR3.

 

The reason why I think there is no CF connector is starting with GCN 2.0/ R9 290X ( NOT THE R9 M290X), crossfire cables were removed from all AMD cards going forward, and use XDMA instead to communicate directly over PCIe, which is a superior technology to nGreedia's SLI bridge system. AMD's requirement for XDMA to work is fairly lax, so there is a strong chance it can work in our systems.

 

Well the R9-M295X lack the CF connector as well, but yes, the first one was the R9-290X.

I'm eying this listing for a couple of days now. BTW this is not "a random Chinese site", it's HUGE in China, but you still rely on the seller's honesty and when overseas, things are getting even more complicated, that's why I'm hesitant, otherwise I'd bought one already (and I guess that's what @Robbo99999 meant).

An user in the "EliteBook/ZBook" subforum said that now one can register with his/her phone number. Last time I tried it required Chinese number (I'd guess that it's still limited to the countries they now ship - was China only, now they are 5 or 6 - USA, Japan and a few others). You can use Google Chrome, since it renders the whole page translated, unlike any other browser, well understandably it wont translate pictures.

 

Now that sounds pretty good! After the Pascal-fiasko in terms of upgradeability, I am really happy that AMD at last provided a decent card (GTX 980 performance) which we (hopefully) can stuff into our beloved rigs!

If that comes true, I'm curious to find out how good ocability of these cards will be. Would be fantastic, if we could reach 1070 (SLI) level! I like to show NGreedia my middle ****** this time! You guys know what I mean!

 

If you agree to pay ~10% fee you can order through agencies like taobao focus. I have few for my country so googled one for USA. But agency must be trustfull too.

300$... wow if it's compatible...

 

I really have no experiences dealing with agencies outside of ebay.

I will wait until these shining gems will be offered through ebay.

 

Does anyone think these AMD MXM GPUs will get the same driver support as the existing mobile & desktop gaming GPUs? I say this because all the slides are pointing to the E9550 as being for embedded systems like casino gaming or medical imaging & the like - this makes me think they won't get conventional gaming drivers?

EDIT: news reaches guru3d on these GPUs, not sure if any new info in relation to an article earlier linked. http://www.guru3d.com/news-story/am...9260-and-e9550-graphics-processing-units.html

 

Yeah probably going to be 400-500 on eBay..

Is anyone brave enough to pull the plug and give it a test now?

If I would pull the trigger via this chinese agency, I had at least to pay 19% tax on it.

So, if this one would come 400€ on ebay, I would be fine with it!

 

This TaoBao Page is a joke! Translation doesn't work at all. I have no clue how to order two of these with only Mandarine as the only language choice....

 

The specs of the MXM form factor closely resemble the RX 480 4 GB than the RX 480 8 GB. I wonder if it can turbo to 1266 MHz.

 

LOL, English TaoBao is called Aliexpress. TaoBao is for Chinese people, internal market. Sellers who also know English duplicate listings on Aliexpress with 30% higher price. This is why those people who want to buy from Tao are looking for local agencies.

 

Hm, couldn't find the 480 rx on aliexpress.com....

 

Where is D2 ultima

This looks interesting fellas! I will wait for some guinea pig testers oops I mean willing enthusiasts to try it out first before pulling the trigger

If you can direct me through this mandarine website, I would pull the trigger for two of them!

Happy guinea pig testers: here I come!

 

Oh man I really hope these will work in my Alienware 18. That would give it a new lease on life without paying an arm an a leg to upgrade to 980m's. I'll be lurking in the shadows of this forum with a half chub waiting for some good news people....

 

Which don't work without issues in the Alienware 18 anyway! (980M)

 

Good for you friend. Fingers crossed and I hope things run smoothly. Look forward to following how you go.

 

I'm waiting for a functional upgrade for my 970M, too. Nvidia fails to deliver...
Please AMD, step into this gap!

 

Your overclocked 970M has gotta be pretty good already though no? If you could overclock it to 1500Mhz then wouldn't that be easily on par with a 980M and only a small gap to the desktop 980 then (which is same speed as RX 480).

 

Yeah, but that does not say much! I can ocing my 970m's to +350core/+480mem/+112,5mv easily. But only for benchmarking purposes. For playing games only ocing till +150core/+220mem/0mv is working.

So getting a RX 480 which runs on par with a GTX 980 should be a nice upgrade indeed (and kinda cheap in comparison to a GTX 980m). I'm curious how good the ocability will be on the RX 480; Fingers crossed!

 

1500 is impossible. It's not even close. +200 is the maximum. More voltage doesn't help. Don't know why, but that is how she behaves.

 

maxwell is just waaay too fidgety concerning voltage to get any real-life stability out of it.... max OC at stock voltage is best bet, combined with max vRAM OC. at least these were my findings thus far...

for benching, thats another matter altogether

 

i'm not so sure about this. RX 480 can get pretty hot.

 

Hm, RX480 is on par with Maxwell, maybe a tad more efficient. So with a lil bit downclocking and undervolting it should be possible to cool it if a 980m did fit. But that's only one small part of the problem.

 

That's my guess as well - downclocked = 980m, like the same in every way - cooling, performance, minus the price tag; reference = 980DTM (the Clevo one) with lower TDP, and yeah I wont even mention the price tag, or the packaging (MXM-B )

Whaa? He's gone?! I'm shocked LOL

BTW I'm actively ignoring him, so I really didn't know.

 

I just got my 2920XM installed in my laptop. I've upped it to 4.0Ghz using XTU v2.1 and Throttlestop, but it does throttle to about 3.8Ghz after a relatively short time running wprime1024. Seems to throttle at about 83 degC, it's not power limits because they're set at 99W for both long & short duration Turbo - it's using over 80 odd Watts during wprime1024 test. Anyone know how to undervolt this CPU? I know off topic, but hoping for a simple short reply that would point me in right direction. I can't find undervolting options in XTU v2.1, nor in Throttlestop (both v6.00 & latest v8.20). Any ideas, I'm hoping to run 4.0Ghz with a slight undervolt if I can?


(pretty pleased with CPU so far, at stock I completed wprime1024 v1.55 in 243 seconds which is very good for a 2920XM, and I got 9403 Physics score in 3DMark11 with CPU overclocked to 4.0Ghz).

 

3.8 ghz is pretty sweet already for a 2920xm unfortunately, there are no software undervolting options for sandy bridge chips, unless u have respective options for that in the bios.

Maybe if you just max out all sliders except voltage and try running stress test again with Fn+1

 

Cheers Jaybee! It remains at 4Ghz on all threads during gaming, I left it on a benchmark loop for about 20mins running F1 2015 (with all CPU particle effects turned up), which is the most intensive CPU game I own. Gonna try it with some proper enjoyable gaming now & see how it goes. (Might tweak it in future so that 1&2 cores are above 4Ghz, and 3&4 cores remain at 4Ghz, currently just got it set at 4GHz across the board.)

 

keep us updated on that, sounds very promising indeed

on another note (and back to thread topic):

more info popping up on standard mxm rx480, although in this case usage is intended for embedded systems, such as gambling in casinos or medical VR. most interesting side notes to take away here:

1) comes in standard 3.0b mxm form factor
2) full rx480 with identical gflops specification and full amount of shaders
3) TDP rating of UP TO 95W
4) only stated difference between these gpus and regular rx models is supposed to be in the drivers, but no more details on that.
5) release date end of Q4/16 for rx480 and beginning of Q4/16 for rx470 equivalent

article is in german, but google translate is your friend as usual enjoy!

I want that thing, may it be called 9550 or RX480, or last hope of fobbed mobile Maxwell owners!

 

Yes, I noticed that the RX 480 (I mean E9550) was intended for embedded stuff such as gambling casinos, medical VR, etc, I mentioned a few pages back that I had concerns that driver support might be different for these cards as a result, but I agree that the specs are very promising indeed for a mobile form factor GPU - impressive power (Gflops) for the TDP of just 95W! My 2920XM needs a faster GPU now - haha!

 

Easy there, you haven't even enjoyed it! Play with it a bit, show it your attention, maybe you'll get to 4.2GHz on all 4. The RX 480 would overshadow it and it would get envious and downclock to 1.2GHz LOL

From zero to 2 RX 480s in about a week. That's AWESOME! The question is, get the 150W, or wait the 95W. Neither of the two would be an easy buy. I hope that I'd be proven wrong, especially on the second. There's also that thing that no one mentions pricing on the E9550. If Zentrica's R9-M295X is anything to go by (it was after the same market after all), it wont come cheap and most likely would require bulk buying, or whatever it is called (i.e. more than one piece, 10 in Zentrica's case).

 

There was a joke about "Don't jump to new Windows until the first Service Pack". Well, someone who had 7970m would suggest not to buy new AMD GPU until rev. 1.2

 

Even though it seems the E9550 is for embeded systems, from a technical point of view, its a desktop 480 with a TDP of 95W in MXM Type B format.
So, it should be laptop compatible (considering its using the same interface and overall layout/design).

What I don't understand is... if AMD was already targeting the embedded systems with these GPU's, why didn't they simply use and announce them for consumer laptops as well?

Sure, there might be some issues with people questioning 'how come the mobile parts are more power efficient', but the reality is that the differences are smaller than expected.
When undervolted, the 480 draws 120W of power... so its pretty much the same like 1060, but while operating on lower clocks.
The 95W for laptop parts could easily account for binning.

 

Just to be clear, the E9550 and the RX480 MXM cards are two different cards right?

 

I believe they are the same card...

 

I don't know what to believe to be honest. When the news about the 150W modules broke, I thought that they are the official ones. Now I know that they are GeCube, but this is just the manufacturer. Who made the order, or do they made them "just like that"?.. No idea. I do think that the first modules (GeCube RX 480) use desktop chips, while the just announced (E9550) use binned ones. Time will tell... Hopefully (means both running in laptops so we can get an idea about the performance).

 

Pretty sure they're different though. They may use the same Polaris 10 chip but one is a full fledged desktop chip with everything that the desktop card has to offer at 150W tdp which should use standard drivers. While the other is an embedded version which may be binned and have lower clocks and 95w tdp with maybe special drivers?

Update:

Okay some things I asked the people selling the RX480 MXM:

1) They will not ship to the US or do international shipping(they said they don't know how???)

2) The cards will be released in two months

3) They don't know if the cards will support crossfire, they will test it when they can

That's all I got.

 

either you know someone from china to help you with the shipping or use a third party service.

 

Thanks for doing some digging!

 

Specs-wise, they appear to be the same.
Unless the E9550 is missing certain hardware from regular 480, or has it but is simply disabled (AMD would in that case likely go the disabled route for lowering the overall costs in terms of manufacturing - like they did with 480 4GB - the other 4GB was on various cards disabled).

But, there's something else to be taken into account... these GPU's have a much later release date (well after the initial debut of desktop cards), so it wouldn't be impossible for AMD to improve on their TDP as they become more familiar with 14nm process and see the practical results of how their desktop chips perform.

Binning for laptops almost always resulted in reduction of TDP, and AMD has a lot of room for maneuvering in terms of undervolting.
So, going from 125-130W (undervolted) to say 95W (binned) doesn't seem impossible without sacrificing performance... especially if silicon quality is good (and most newly released desktop 480's seem to have better silicon quality).

From here:
http://www.itechpost.com/articles/3...cards-e9260-and-e9550-first-look-at-specs.htm

" Hot Hardware also compared the E9550 as the embedded equivalent of the Radeon RX 480. It has 36 compute units, 2304 stream processor, a base clock of 1120 MHz and up to 5.8 TFLOPs at sub-95 TDP board power. Its 8 GB of GDDR5 uses a 256-bit memory interface running at 1750 MHz."

If that extract is correct, then there do not appear to be ANY deviations from the desktop 480.
In that case, I would imagine that AMD adjusted the voltages of both the core clocks and VRAM (which seems to be especially power hungry on desktop) while also binning it as much as possible.

If the card however is operating at the very least on base clocks of 1120Mhz under full load, then yeah, it would likely be slower than the desktop counterpart by about 13% in total (not a big difference really), and it would also help reducing the power draw of the GPU in total.

If the base clocks are the full load clocks for E9550, then it should be possible to increase the clocks to desktop 480 levels at a TDP of about 110W or 120W most likely (considering that power draw jumps by quite a bit when increasing core clocks).

I'd be ok with 13% less than desktop 480 performance... since it would still technically qualify as a desktop 480 with marginally reduced clock speed - and it would probably perform a lot better than what 1060 in most laptop does (though, we know that this can be addressed with adequate cooling systems).

What I don't understand is... why aren't laptop manufacturers using at the very least liquid cooling in laptops?
Acer did it with their ultrabook here:
http://www.laptopmag.com/articles/acer-switch-12-alpha-features-price

Thickness-wise, it doesn't really take anything away from a laptop - heck it would probably reduce the overall space requirements and improve efficiency (especially for laptops that have desktop grade CPU's inside them).



Anyway... point is, that from a hardware point of view... E9550 and RX 480 seem to be identical in all things. Eve the base core clocks are the same... the E9550 might not simply have boost clocks operational, and if it does, then AMD likely optimized the voltages and binned the heck out of the 480.

I'd definitely like to see E9550 used for consumer grade laptops. AMD have a solid product here that can be used for such a purpose (and it would still outclass 1060 in DX12 while offering similar DX11 performance).

 

im guessing difference between E9550 and rx480 would be smth like the difference between quadro and geforce cards: identical hardware, but slightly different hardware ids so that differing drivers are required.

I was thinking along the same lines, and its possible that this is exactly how these GPU's were intended to be used.
However, that still doesn't prevent AMD from using them in consumer laptops.
The TDP is far better/more suitable for laptops while having identical specs - if anything, they could probably use the mobile version as a guideline to improving the TDP on the desktop side - but then again, they were able to create the Fury Nano with only 10% drop in performance and voltage optimizations (a review of Fury cards revealed that they can also be undervolted which also increased their baseline performance by removing the thermal throttling and be within or less than 10% differential of Maxwell in terms of power consumption).

 

If the E9550 is an embedded card and does use different drivers then there's a chance it might not support crossfire. Whereas the RX480 mxm card seems to be a desktop card in an mxm form factor and might support crossfire and use regular drivers.

 

well, crossfire aside, one could always mod the drivers to support the E9550 cards and recognize them as regular rx480s ^^

Sent from my Huawei Mate 8 NXT-AL10

 

Why would crossfire be out of the question?
I mean, embedded solutions might not have CF support by default, but that might be due to design choice from manufacturers, not necessarily AMD itself.

Although, 95W + 95W = 190W for 2x E9550.
10W higher than 1080, but not an unmanageable number... and it should still be cheaper than 1080 while offering superior DX12 performance.

 

I am tempted to get an M17x r3 if rc 480 works in it..m15x is getting a bit long in the tooth

Go the whole 9 yards and grab a M18x R2....I've owned the M15x (the classic), M17x R3 (where I started with Alienware), M17x R2, M18x R1 (still own this one), and M18x R2 (my baby), as well as the Alienware 18 (bastard child). No reason to go with the sandy bridge based Alienwares over their IVB counterparts unless you plan to hackintosh.
