Is there any info on TMUs/ROPs? For either console? |
I think its safe to assume both will have 64 ROPs. Their not hungry/powerfull enough to require more.
TMUs depends on the "core" counts of both.
Ex:
Xbox series X = 52 CU's (x64 shaders pr CU)= 3328 shaders = 208 TMUs? (16 shaders pr TMU) + 64 ROPs (these are just a fixed number)
While for a Playstation 5, that would look like:
Playstation 5 = 36 CU's (x64 shaders pr CU) = 2304 shaders = 144 TMUs? (16 shaders pr TMU) + 64 ROPs (these are just a fixed number)
^ this is just a educated guess ( I could be wrong)
How this relates to "Pixel Rate" or "Texture Rate" then becomes a issue of math, useing the clock speeds both GPUs are running at.
-------------------
Texture Filter Rate = Core Clock * TMUs.
"In the case of the GTX 980's GM204 chip, that would be 128 TMUs * 1126 = 144128. Note that the 1126 clock speed is measured as MHz, or millions of oscillations per second, so that'd actually be 128 * 1126MHz = 144.1GT/s; in other numbers, 128 * 1126 * (1000/s) = 144.1GT/s."
Xbox Series X: (useing 208 TMUs) = 208 x 1825 = 379,600 (379,6 GT/s)
Playstation 5: (useing 144 TMUs) = 144 x 2230 = 321,120 (321,1 GT/s)
Pixel Rate is more or less the same, its just ROPs x core clocks.
So Playstation 5 should have a advantage in Pixel Rate as I understand it, but have a lower Texture filter rate.
The rest is the Flops numbers, and memory bandwidth.
Playstation 5 is a slower GPU part than the series x.
