Weirdly they're advertising "1 petaflop of AI performance at FP4 precision" [1] when they're advertising the 5090 [2] as having 3352 "AI TOPS" (presumably equivalent to "3 petaflops at FP4 precision"). The closest graphics card they're selling is the 5070 with a GPU performing at 988 "AI TOPS" [2]....

It seems like they're entirely different units?

TOPS means Tera Operations Per Second.

Petaflops means Peta Floating Point Operations Per Second.

... which, at least to my uneducated mind here, doesn't sound comparable.

I'm assuming that the operations being referred to in both cases are fp4 floating point operations. Mostly because

1. That's used for AI, so it's plausibly what they mean by "AI OPS"

2. It's generally a safe bet that the marketing numbers NVIDIA gives you is going to be for the fastest operations on the computers, and that those are the same for both computers when they're based on the same architecture.

Other than that, Terra is 10^12, Peta is 10^15, so 3352 Tera ops is 3.352 Peta ops and so on.
