wut?
The main difference is the 6800 have 128mb of IC but it have also 4mb of l2 (x60cu) for the entire gpu vs 5mb (x52cu) of the Xsx ...
The xsx have 5mb L2 cache for the whole GPU, level 1 cache for the Shader Array, and the LDS for the dual CU just like every other rdna2 gpu
the arrays of the xsx are 2x12 2x14
Let me help you. here is a picture, half of the whats drawn for 6700, 3/4 for 6800,
or 2 shader engines for 6700 and 3 shader engines for 6800
Ps5 and XSX BOTH have 2 shader engines.
The only Chip that has more than 10 CU per Array in RDNA2 is XSX.....
So XSX GPU has to share more things;....How does that work out ?
So XSX and Ps5 and 6700...
No bigger parameter cache
No bigger L1
No bigger LDS
No bigger command and GE processing
I can throw in a few more if you like ?
