| JEMC said: @HoloDust: Thanks for the chart. What is that Redwood speculation? Is it the one saying that Wii U's GPU is based on the HD 57xx series? About PS3 and the GFLOPS, if I remember correctly it was thanks to the Cell, not the RSX. That's why it was used at Folding@Home or another of those incentives. |
Yeah, HD 55xx / Mobility HD 57xx - I came across it somewhere (though they mentioned 5670 clocks, but it has too high TDP in my opinion), so I thought to include it - it's size is 104mm^2, so it's seems like good candidate, considering its performance is similar to other rumoured. And honestly, I think it would make more sense than shrinking RV740 to 40nm and clocking it so low to fit into their TDP. But, still just wild guesses I suppose, there are opposing rumours claiming DirectX 10.1 and DirectX 11 equivalent GPUs inside.
As for RSX GFLOPS number I took it from wiki, and I find it very strange - actually, to me it makes no sense at all (any one with greater knowledge mind to explain?), so I was guessing it might be in combo with Cell (Cell number is also wrong, full Cell has 230.4, PS3 version can only do 179GFLOPS (1PPE+6SPE, 25.6 per element)), but that doesn't add up good also, so I'm puzzled. Discrepancy in Xenos is more understandable cause of nature of VLIW5 (5th fat one doesn't seem to be used much), so it can be argued that it's 120G Shader ops/s - 240GFLOPS, or 96/192, but I put official specs.
