| Intrinsic said: People need to get this straight. The PS4 "GPU" is 18CUs @1.8+TF. PS4k "GPU" 36CUs @ 4.1TF (more compute units and higher clock) XB1 GPU is 12CUs @ 1.2+TF If the XB1.5 GPU is going to be 6TF it would need to be packing 56 compute units!!!!!! the ONLY card AMD has that has that many compute units is the R9 Fury. And that "GPU" costs $550. $550. And we have not even started talking about the CPU. I think some people need to get a little realistic. |
False. TFlops = Alu/Aggregate Shader speed x 2 ops/clock. ALU speed = # shaders X GPU clock speed. You do not need 56 CUs to get there. 14nm process will allow AMD to increase clocks.
1. Polaris 10 will have 150W TDP and 2304-2560 shaders clocked at 1266mhz or so. Using the lower end version = 2304 Stream Processors X 1266mhz X 2 ops = 5.8Tflops. Rumored MSRP is $249-299 this summer.
2. Polaris 10 benchmarks show it's almost as fast as the Fury, while using half the power:

3. By 2017, MS will be able to increase GPU clocks more and add 8GB GDDR5X if they wanted to. Either way, 5-6 TFlops will be achievable with a 120-150W Polaris 10 chips; and these are mid-range 14nm AMD cards for 1st 14nm generation.
4. Polaris 10's die size is rumored at 232mm2, easily small enough to combine with a Zen CPU.
