"It should end faster of the 580" . I dont understand why he base his article on that. new architecture, 28nm, new series ...

365mm2 definitely leaves them to release an update later in 28nm
huum, Cypress was 334mm2... but 365mm2, is a bit too much far of the estimation made..
slide says "embago" lol
Do we have any knowledge of how the GCN shaders will compared to those from the R600 architecture? IE how do 2048 GCN cores compare to 2048 VLIW4 cores (suped up 6970 effectively)
GCN will have higher efficiency and run-time utilization than VLIW. It will have some sort of limited dynamic scheduling, but nothing exotic like in Fermi. GCN will rely on the sheer amount of in-flight threads/wavefronts to choose from and hide memory access latency and other pipeline stalls, and much less on the compiler.Quote:

That isn't idle board power.Quote:

Hah!
Totally faked OBR slides... the one just above is real.
OBR's... wrong font, old visual style and faked specbars (intentionally prolonged to give the impression that AMD were giving super unrealistic numbers)
What a c*nt.
Looks interesting I guess. TBH I'm more intrigued at the rumors of GK100 having 1024 CUDA Cores; GCN would have to be at least 70% more efficient for AMD to keep up in single gpu setups from my math (I assumed linear performance scaling, and gtx 580 being 10% faster than 6970). I guess that means they always have the 7990 to go against NVidia's high end, but power consumption would be astronomical as would price
I will wait to see Nvidia vs ATI before making any decisions. There are so many architecture changes happening with this new generation of videocards (from both companies) that I just want to see why those changes are being made. Overall I'm just excited for the 28nm revolution.
Agreed on the 28nm. I've held off on a gpu upgrade for a long time now purely because I didn't want a 40nm product. With that being said, doing the math you can see that GCN would have to be drastically more efficient than VLIW to compete with GK100. From everything we've heard, it seems that the majority of changes were done with the workstation market in mind (impyling that I don't think we'll see this round go to AMD).
I like big bars and I cannot lie ...Quote:

IF GK100 will have 1024 CUDA cores. It's all just rumors and we don't know how fast these will be yet.Quote:

Still using a vapour chamber? I thought they were switching to those liquid chambers, or is 6th generation vapour chamber the same thing?
These slides look a bit more legit that the OBR ones, but still I wouldn't look too deep into performance numbers. Nice to see DX11.1 and PCI-e 3.0 supported though. :)
I sure hope those slides are not another round of spin.
I semi lost faith in AMD after all that has gone on with BD.

The trend makes sense though, think about it:Quote:

Considering the pattern NV has been following for quite a while now, it wouldn't surprise me if it does have 1024 CUDA cores. Though I do wonder how they could possibly cool something of that monstrosity. Even at 28nm that chip would have to be over 500 mm^2 not to mention consume a butt load of power
What makes me nervous is that all those games on the last slide use tessellation, If I were marketing something I'd show off what I improved... a lot.
I want something faster than my 480 and I refuse to go dual cards ever again, hope this sucker will be epic. Can't wait for the reviews.
agreed, if tessellation games increased 60-250% then games that were not using much tessellation might be only 40-60% fasterQuote:

G80 » GT200 : 90 nm » 65 nm, 484 mm^2 » 576 mm^2 (1.19x), 128 » 240 (1.88x) : 1.58x CCs/mm^2
GT200b » GF100 : 55 nm » 40 nm, 470 mm^2 » 530 mm^2 (1.13x), 240 » 512 (2.13x) : 1.89x CCs/mm^2
And that's not to mention TDPs. So if GF110 » Kepler is anything like the above in terms of CCs/mm^2 increase, I think there would be fewer than 1024 CCs in the top-end Kepler chip unless they pull some magic with the SPs or other stuff or they conjure up a chip close to 600 mm^2. My guess is 640 < CCs ≤ 960.
Thanks for clarifying, I was wondering what that chart meant.Quote:

Yes + there's some faked pages who turn around ... modified one from 6970 launch ,so take all this with a lot of precaution ( the last slide look correct )..

Is the launch really advanced to the 22?
