An RTX 4090 does 1.3 TFLOPS (FP64) at TDP 450 W [2], so 3 GFLOPS/W. If so, this is substantially better, and built on a core that can use standard tooling. [edited]

They don't say how much money you can cram onto the board, or what the memory bandwidth is; just that it's a lot...

Freudian slip? :)

Where did you see that? Which core?

Or, did you mean an open and license-free ISA specification?

Yepp, I meant an ISA that doesn't require vendor tooling (as opposed to CUDA.)
