Intel 'Sierra Forest' Xeon Server CPUs

I've been getting back into the CPU limelight after a few years of burnout from too much info and life goals.

This new fancy E core stuff kids talk about sure looks interesting and I see the new Xeon has butt load of cores which some interesting technologies!

However there is one thing that still itches me brain, these CPUs seem to be marketed for data centres a lot about rack density?

If I'm right in ELI5, that just means less servers with better performance overall right?

I only quiz about their advertisement for data centres since you often seen a lot of prior gen Xeons in servers, heck the school I worked for in the past had a decent end of these processors for VM use.

Am I right in thinking THESE new fancy Xeons are "data centre" only versions?

Forgive me for my ignorance on this subject.

One thing notable of Sierra Forest is that the CPUs don't have SMT (only 1 thread per core), so in theory it doesn't suffer from speculative execution attacks.

Epyc CPUs still provides more PCIE lanes, which is crucial for GPUs.

I did hear that they're killing off hyper threading which is a bummer but I guess those P cores would make up for it.

Intel generally target Xeon products for enterprise servers and workstations. They usually also come with very high price tag to differentiate from retail offering. For most of us, it’s generally drooling over them for 5 years, wait until they’re out of warranty, and buy them from companies offloading servers that are no longer under warranty for a still-hefty-but-more-affordable price.
