@tjkreidl Interesting that ASRock is also using the NUC name. ASUS also has the new NUC15. This new ASRock box uses the Ultra 7 255H which has 6P/8E/2LPE cores (no HT).

Largely depends on your homelab. I'm currently in my homelab using a 3970X Threadripper But, I got that board/chip free after we did a client upgrade to the new Threadrippers, and there isn't a single amount of money I could save on energy to match that savings. That said, think about what you need to use your homelab configuration for; I often find that the availability of RAM and total available cores. But I guess different needs matter too..
