AMD added support for Polaris to Linux today.
https://lists.freedesktop.org/archives/dri-devel/2016-March/103422.html

Along with that we saw entries of Baffin and Ellesmere.
Quote:
Baffin: 67E0, 67E1, 67E8, 67E9, 67EB, 67FF
Ellesmere: 67C0, 67DF
Luckily, one AMD developer shed some light on the entries to find out what is what:
Quote:
Michael We're calling them Polaris 10 (was Ellesmere) and Polaris 11 (was Baffin) now, any chance you could tweak the article accordingly ?

Thanks !
Specifications of one upcoming Polaris 10 GPU have also been found.
Its name is "67DF:C4" which is Polaris 10/Ellesmere if you look at the list above.

Specifications of this Ellesmere is 2304 cores running at 800MHz, 36 CUs (which means 64 cores per compute units as before) and 256bit with 8GB VRAM running at 1500MHz.

FYI: Polaris 10 is AMD`s upcoming high end GPU from the Polaris architecture. Which means that atleast some of these will have GDDR5

It would be pretty cool if it said "Polaris" on the box.

Uhh, actually, the Ellesmere is supposed to be the low end and Baffin/XT to be the mid-range ones, thats how i remember them. Also, 1500Mhz on Memory at stock is crazy upgrade over the last GCN, that has it around 1300.

No,

Polaris 10 is high end. Didnt you watch AMDs presentation a week ago?
Polaris 10 beat Fury X.

Ellesmere is Polaris 10 according to AMD themselves. See OP

Maybe in some crazy dream.
If polaris 10 have 2304SP,256bit 6Ghz DDR5 with 192GB/s it will be miracle if polaris 10 can match even 390/390x.

No way Its faster than FuryX

Yeah to beat Furyx with 2304Sp and 256bit 6Ghz DDR5 they need increase IPC by around 50-60% and have far better delta compression.

The GPU we found could be the disabled Polaris 10, while the full have say 2560 cores.

AMD have said both that Polaris 10 is the high end and that the GPU in OP is Polaris 10. Thats all we know. Perhaps they have increased performance in the cores then. Unlike Pascal which is looking to be Maxwell 2.0, Polaris is redesigned and brand new. They could have made big changes to the architecture and core performance

Polaris 10 beat Fury X.
Mid range matches/beats high end of last generation, especially with significant jumps in architecture and manufacturing process. The last time we had a manufacturing process change you got this in 1 gen!

http://anandtech.com/bench/product/1444?vs=1441

NV & AMD also like to call middle-line chips "high end" for a period of time with new gens. If it matches/beats high end of previous gen, that's what they'll call it - nevermind that they might have a chip 1.5x + faster already made.

yeah we do not know if the 2304sp gpu is a fully enabled Polaris 10. Raja Koduri said that Polaris is a huge improvement and I think we could see a 2304-2560 sp Polaris 10 beat Fury X due to vastly improved architecture.

"Yes. We have two versions of these FinFET GPUs. Both are extremely power efficient. This is Polaris 10 and that's Polaris 11. In terms of what we've done at the high level, it's our most revolutionary jump in performance so far. We've redesigned many blocks in our cores. We've redesigned the main processor, a new geometry processor, a completely new fourth-generation Graphics Core Next with a very high increase in performance. We have new multimedia cores, a new display engine. This is very early silicon, by the way. We have much more performance optimization to do in the coming months. "

My speculation:

Polaris11-1280SP 128bit 5-6Ghz DDR5 120mm SKU 4GBVram
Cutdown version 1024sp
Polaris10-2560SP 256bit 6Ghz DDR5 232mm2 SKU 8GB Vram
cutdown version 2304SP

FULL polaris11-R9 285/380 performance
FULL Polaris10-390x/GTX980 performance

If final clocks are better than 800Mhz(atleast 1Ghz).If its only 800Mhz i dont see it match 390x/GTX980.

GTX960 does not beat 780 Ti. There are 4 class of GPUs. Low end, Mid-range, High end, enthusiast. Going from generation to generation you will see high end beating last gen enthusiast. This is not always the case those.

Project 'Greenland'; Leading project of Graphic IP v9.0

As leading chip of first graphic IP v9.0 generation, it has full capacity of 4096 shader processor, along with whole new SOC v15 architecture.
Lead a team of 7 for this leading project to tackle all new issues pop up in IP and SOC, bring up major graphic features and legacy feature in SOC, porting IP level test cases and verifying functionality on SOC level.
IP tables from the open source driver don't show changes for the shader core of Polaris10/11 chips. So the shaders are similar to those in Tonga/Fiji, but the ROP ratio and the front end changes.

Code:

64ROPs with pixel fillrate of Fury and improved front end should propel it to 390X performance easily despite shader deficiency. How well it clocks at stock would decide where it ends up.

Even though maxwell was NOT a new manufacturing process, just a revision on 28nm.. 970 is roughly equal to 780ti and the 980ti is ~70% faster.

970 is the midrange GPU for Maxwell.

GM200 is literally three times faster than GM206 - the chip used for the 960 - and it would be wrong to call the 960 midrange because of that.

If we assume full Polaris 10 is 2560 cores. And this one beats Fury X, it means Polaris cores perform 30%+ better than GCN cores. Thats absolutely possible through new architecture.

Here is R9 390, which is also 2560 core GPU. Fury X is about 30% faster.

the low core clock + low mem bus do play to amd perf/watts claims for sure. Performance can be brought in other ways and this being a new architecture points to that.

In another thread said that the possibility that the Polaris 10 that run the bench is a cutdown version and the full die will have 2560 cores. As it seems that is very likely, let's take that number.
2560 with the power of 4096 cores takes that each core has to be 60% better to equal the 4096 version. Didn't Nvidia bring GTX970 with 1664 cores equalising the 780Ti with 2880 cores?
If Nvidia can make a 73% more power from their cores, doen't AMD do a 60% improvement? I think so

Also, the gmc in the table with the differents iterations of GCN that is posted earlier, has to be the memory controller (graphics memory controller?) So 8.1 is a improvement over the 8.0 but it's not the 8.5 that Fiji has. So no HBM this time. I remember Mahigan saying that Polaris 10 will have HBM, so maybe it's false.

Another thing is that maybe is a very weak bandwith for a 390-390X replacement. I don't know, but seems too low. 6Ghz is very conservative. Let's hope some 8Ghz in the final version.

There are a lot versions of the Polaris 11 silicon let's take that as laptop versions and 2 desktop versions (380 and 370 replacement). It seems that from the bottom to the top (150-500), we are getting Polaris and 14n love. Also, 800Mhz...let's hope another 7970 case. 1200Mhz check in, 1100Mhz dayly. It seems that we are using some dense libraries again...

So Polaris 10 is at FuryX like GTX970 to 780Ti. I'm in, boy.
