Info AMD CDNA Compute GPU architecture

[soresu]

Seems like AMD is truly creating a permanent separation in GPU between gaming and compute focused uArch - the new compute focused uArch family is called CDNA.



Hopefully this doesn't mean any significant drop in async compute and general Vulkan compute performance with RDNA.

Vega20 still had rasterization hardware in it. It was a full blown GPU.

CDNA cards aren't video cards. They don't have the ability to output video. So yes, it will be larger than Vega20, but unlikely to be double as it had lots of stuff removed that Vega20 had.

TPU says 750mm2 compared to 330mm2 for Vega20. Should wait for some actual measurements, I don't know where they got those numbers.

Yeah, I had seen that. But it just doesn't seem correct. Not when we look at the size of Navi21 for comparison to Vega20.
