The posts listing a concrete model mentioned the EPYC 7571 which has a single thread passmark of 1934. I believe first gen EPYC had an IPC pretty close to Intel.
On the other hand, if I take the all core passmark result divided by cores (since you pay per-core), it's 26659/24 = 1110 vs 27445/32 = 857.
They seem close enough that it's not possible to predict which one is better without actually benchmarking on AWS, since it'll depend on the clock rate they're able to sustain in AWS's setup.
In any case, I don't see any significant cost savings potential for AMD on AWS, which was the point of my original post.
