Actually, he is agreeing with me. When he says "It has a little be more ALU than it would if you were strictly thinking about graphics... ." (emphasis added) It implies the GPU would be used for GPGPU purposes. Not saying that the additional four CUs can't be used for rendering, simply that at 14 CUs you're saturating the memory bandwidth. You only have 176GB/s that you can pipe data through. That's peak efficiency, something not realized in the realworld. At 80% efficiency you get 140GB/s (80% of the PS4's 176GB/s) through that pipe. Since the PS4 has 50% more CUs than the Xbox One's GPU, and at 12 CUs the Xbox One is generating 146GB/s, then it stands to reason that at 50% more power the PS4 would saturate the 176GB/s if all 18 CUs are running (219GB/s). If it has, as you've said, been disproven please provide a link. |
lol so what's your reasoning that the 2.56 tflop 20 cu amd 7870 has a memory bandwidth of 154gb/s. Did amd somehow engineer a gimped "unbalanced" gpu?
