I'm curious - what are people running on boxes like these that makes good use of 80 cores and 768 GB of RAM?
I'd throw some video encoding work at something like that. Easy enough to eat up all that ram and the cores.

No. This core is terrible at encoding.
EDIT: And encoding is limited to ~16 cores in practice. It seems like after that, the communication between threads get too much to be useful. Unless you plan to be doing 5-simultaneous encodings at a time, then you're gonna have to find something else to do with all those cores.
Most of the new encoding tools split videos by scene and then run parallel encodes from there, such as av1an.
For a decently sized video (say a TV episode) there's usually like 100 split points to divy out to encoders.
