My recommendation here is to wait a couple of months until Ryzen 3 comes out in laptops. While an IPC boost is nice (rumors are between 10% - 20%) the real reason I say this is because the new 7nm process should net a significant reduction in energy consumption. AMDs demo of Zen 3 in January showed their 8c/16t CPU performed almost identical to Intel's 9900k with 1/3 less the power consumption.

Ryzen Mobile 3000-Series was already launched at CES, it's already available in certain models. It's also worth mentioning that these are 12nm chips based on Zen+, not 7nm and Zen 2 (the new architecture launching in a couple of weeks).

Yep. The 7nm is coming in Q3/Q4 as the Ryzen 3000 for desktop, the mobile ones based on 7nm aren't even on the roadmap yet, and if, would be the mobile Ryzen 4000 series.
Mobile AMD chips are always lagging around one year behind the desktop ones. So mobile Zen 2 (7nm) will come out next year probably.

Thanks for the detailed reply. If I don’t game does it still apply? I run VMs sometimes but usually have no issues since I tend to stock up on RAM.
If your VMs consume CPU, as opposed to mostly waiting, many cores with low power consumption are beneficial.
If all the VMs do is waiting for a network packet 99.9% of time, then not so much.

It's not anything super resource intensive beyond the inherent need for the resources of the VM + host. I just got sick of dealing with some of macOS's idiosynchacies in it's Very Special Epiosde of BSD that is their CLI interface, so I spin up an Xbuntu or Debian image when I have a project. (That + snapshots makes it a lot less painful to try interesting things)
