The Ampre Altra runs from 32 to 128 cores (dear gods that's beautiful), but with that architecture, and the company's stated purpose, it makes more sense in a computer meant to be used as a server rather than a desktop gaming rig. You'd use a chip like that in a Kubernetes cluster for example.
Combined with an Nvidia card, a brand notorious for being a Pain In The Ass in Linuxland, I'm going to go out on a limb here and suggest that the intended purpose of a box like this is a server for AI/ML-based services.
I mean, you can buy it and use it in a general purpose fashion, and yeah, those cores would do wonders for all sorts of compiles. Also, it can be useful if you're like me and do a lot of Dockerised development. Given that most games are x86 only though, sadly this would be no good :-(
