Sorry mate, mostly taking issue with your statement that the RDNA2 architecture doesn't have dedicated RT hardware. I should have made that point clearer.

No problem mate, but I think you've misread...it was "very poor RT, with no dedicated AI hardware"

Ah. Yeah. Did misread that.

In saying that... The A.I Cores is just replicating certain formats from the CU's into separate cores.
RDNA2 supports all the important stuff like bfloat, INT4, INT8... Where RDNA2 falls behind is FP8.

The advantage of separate cores for A.I is that it doesn't tie up CU's used for rasterization/ray tracing, but otherwise they don't technically bring new functionality.

So on a technicality, RDNA2 does have "AI Hardware" just not as separate independent cores... But RDNA3 doesn't support every AI operating on it's A.I cores anyway, so some AI operations fall back onto the regular CU's.

RDNA4 stepped things up further again. - In some instances I am seeing an 8x gain over RDNA2 for AI stuff... A.I video upscaling saw a 12x fold performance improvement depending on algorithm.
