The final numbers are correct, however, the formula is incorrect.CU count x Ops per second x ROPs x Core Frequency = total floating points operations
XBSX: 52*2*64*1.825= 12.15TF (rounded)
PS5: 36*2*64*2.23= 10.28TF (rounded)
ROPs aren't used to calculate CU floating point capabilities as they are separate fixed function execution units.
The 2x64 component comes from:
- 64 as the number of shader cores per CU
- 2 as 2 operations counted from Fused Multiply and Accumulate instruction - a multiply and add, aka FMAC, FMA, FMADD
So the narrative now is xsx uses zen 2 without modifications beyond l3 reduced to 8mb and its gpu is an rdna1 derivative, i.e. Cache and cu setup while ps5 uses zen3 alike l3 cache and it's gpu is rdna2 derivativ e i.e. Cache and cu setup?????
We are discussing driver leaks and patents. Can you be more technical and specific?No, it's wrong, it's the rdna3 that's a ps5 derivate.
