Playstation Tablet 1,850 Posted January 11, 2020 Share Posted January 11, 2020 (edited) Basically, Mr. Cerney (@cerny) customized PS5 APU very in depth to its throughput and legancy (and even a cache). Another word, re-writing the “Teraflop” equation: # of shaders * GPU Clock Speed * Instruction Per Clock (usually 2, but here it could be 3)/1000000= Teraflops So if this is true, the 36 CU @ 2ghz hits 13.8 tflops. So even downclocking from 2ghz would give a good number. Anyways we could be getting more than 2 instructions per clock throwing out the current math we have for the 36CU part.

Playstation Tablet 1,850 Posted January 11, 2020 Author Share Posted January 11, 2020 (edited) Its possible they were always going for 36 CUs for PS4 BC, so they're taking a different approach to their design on the GPU front. Edited January 11, 2020 by Team 2019 Link to post Share on other sites
DynamiteCop 2,149 Posted January 11, 2020 Share Posted January 11, 2020 (edited) That doesn't mean it can execute more, it still has the same FP32 throughput but it can simply fit several smaller things into a single instruction which allows instruction diversification. This is really like a custom play on FP16. The system would still be 9.2 Teraflops, this doesn't change that. Edited January 11, 2020 by DynamiteCop! Link to post Share on other sites
