I believe those numbers are estimated base on FLOPS scaling which is not realistic. They will probably be 20-30% slower in real life.

I'd say, run the full bench with max setting, but also run a selected subset (say 2k-8k) using the slower setting as well, for "scientific purposes"

Infinity Cache is big enough to run the entire FFT out of it, and that has much higher bandwidth. I think Radeon VIIs were severely bottlenecked on memory for PRP tests, so their increased FLOPS...

Can? Yes. Although ... B3>B2 is a bit ambitious. More realistic would be B1<B3<B2<B4.

A 6950xt is 3x faster compared to 3090. 4090 has a little over 2x the DP FLOPS of a 3090, but only about 10% more memory bandwidth. Best case, it will be 2x faster than 3090, so still 1.5x slower...
