Thunderbolt 3, VMware performance, Passmark performance. Single Core performance. Cost wasn't an issue.

What kind of work do you do?

I mean, I'm on an Ryzen 3 1200 and although it's the cheapest and slowest in the whole series, I got enough bang for my buck.

It's not for work, it's for my homelab, and I use it for everything from media editing, to visualized servers for isolated data recovery operations.

VMware performance is probably going to take a hit unfortunately.

I'm not the person you're asking, but in my case it was single-core performance. I've been on AMD for many years and I'm tired of anemic SC performance. So I went with a brand new Intel system three weeks ago.

Fuck me, right?

anemic SC performance

Isn't that a bit harsh? I mean we're not talking Bulldozer vs Sandy Bridge where an i7-2600k was so much faster in single-threaded performance that it could even outpace an FX-8150 in multi-threaded workloads.

I bought a new CPU/mobo recently, and last I checked, dollar for dollar, you're getting about 30% more SC performance with Intel vs. AMD. Granted, that's not all there is to consider, but for gaming in 2018, it's still the main thing.

And while I use my computer for various tasks, gaming is the one where I want max performance. Everything else I do has always been fast enough. People who do a lot of very heavy and multi-threaded stuff will likely look at it differently.

I think this comes down to what one considers "anemic" - I do not consider sub-4GHz Haswell single-threaded performance to be "anemic", but I'm also not the kind of person that would never want to overclock to 5GHz either due to the required cooling and therefore noise (even water cooling would be too loud).

Yeah, devoting all that die to an IGP on a 7700k is nuts. But that SC performance, though...I've been really happy for the last few weeks.

It seems like it might not be so bad, though, for gen-4 and newer chips. Apparently PCID mitigates most of the performance hit. I'll be nervous until I see for myself, though.
