特意找了当前外国论坛上的讨论,当时人们说的是
1、两个都是客制的RDNA,都像是混合了部分RDNA 1和2
2、 So it appears the PS5 is using RDNA1 ROPs, while the XSX is using RDNA2 ROPs.
Locuza on *** has outlined alot of these differences like the ROPs for instance.
"The new Render Backend+ is a lot smaller. Instead of 4 Color ROPs + 16 Z/Stencil ROPs, the new RB+ has 8 Color ROPs + 16 Z/Stencil ROPs. Xbox Series/RDNA2 GPUs have half the amount of Z/Stencil ROPs per SE vs. PS5/RDNA1. PS5 pays a lot more for the Render Backend, area wise."
3、Clock-for-clock, on rasterization they're similar. Using an average of several games, at 1080p RDNA1 wins by 4% and at 1440p RDNA2 wins by 2%.
RDNA2's main advantages are the massive clock bumps, Infinity Cache allowing for lower external bandwidth (in the case of the PC parts) and obviously RT capabilities.
感觉上面说明,RDNA2并不比RDNA1先进很多,所以高频的RDNA1反而有可能赢?
