What controls Turbo Core in Xeons?

Is it just Tmax (ie chip stays at max turbo as long as CPU isn’t too hot) or is it also measuring power draw or other variables?

Asking because I’m pondering building a workstation with one of those cheap v2/v3/v4 Xeons on ebay. Would be great if I can stay near max turbo just by slapping on a good hsf, but it’s less appealing if they’re gonna drop to base ~2.0ghz clocks every time I throw a sustained workload at them.

Goal with this machine is smoother multitasking. The laptop in my sig can do most of what I need but it doesn’t stay responsive while recalculating big Excel sheets, batch processing images, etc. Would be nice to have a bunch of cores so it doesn’t choke on that sort of lightly posted stuff.

Also wanna do some experimenting with ESXi which apparently is pretty core hungry.
