And if i understood correctly, they have also doubled ROPs per GPC. Incredible for NV to go for such a brutal GPU.

These ROPs have nasty implications for AMD who are stuck on 64 ROPs for nearly a decade now? Really worried about AMD.

We know Xbox Series X is a 2SE, 4SA ( 4 x 7WGP/14CU = 56CU) , 64 ROP design with 116 Gpixels/s . The 116 Gpix/s ( 64 x 1.825 Ghz = 116.8) was revealed at Hotchips 2020.

We also know Navi 21 has 4 RBE per SE and has 4 SE as per rogame's findings. So 4 x 4 = 16 RBE.

Navi 10 had 8 RBE per SE ( 4 per SA) with 4 ROP per RBE. Navi 10 had 2 SE for a total of 2 SE x 2SA x 4RBE x 4 = 64 ROP .

Given both Series X and Navi 21 are RDNA2 GPUs I believe the RBE per SE is same in both these GPUs. This would mean AMD has doubled the ROPs per RBE from 4 to 8. Incidentally Ampere has 2 RBE per GPC with 8 ROPs per RBE.

Series X = 2SE x 2SA x 2 RBE x 8 = 64 ROPs

Navi 21 = 4SE x 2SA x 2 RBE x 8 = 128 ROPs

Navi 22 = 3SE x 2SA x 2 RBE x 8 = 96 ROPs

Navi 23 = 2SE x 2SA x 2 RBE x 8 = 64 ROPs
