What exactly did US export limit? FP64 performance?

[–] [email protected] 1 points 1 year ago (1 children)

Fp8 performance per unit die apparently.

The 4090 has 660 fp8 tflops (which is insane when you think about it) and got the ban.

H100 is 1930 Fp8 tflops.

With sparsity both can do upto 2x that

The 4090 has more fp32 performance than the H100 though.

It's not specifically fp8, but TOPS*data size. Absolute limit is 4800, or 5.8/mm^(2). Above either is an outright ban. Above half of either needs a license.
