AMD Radeon VII benchmarks(?)

[rarecoil]

Bumping this thread with multi-GPU benchmarks on ROCm 2.10, because a new Radeon VII is now $500 on sale as they have been EOL instead of $700. I have not experienced heat issues; the cards stay at about 65-ish C under automatic fan control on stock clocks. These cards cost about $2070 US; I use them mainly for DL/ML work where the 16GB HBM2 per card is helpful.

This benchmark was run after getting the cards up to a stable temperature by running a brute force attempt on a single NTLM hash of all zeros for about an hour.
