Using AMD's Ryzen Master to disable most CPU cores would significantly reduce performance, especially for basic activities like web browsing or document editing. Heat generation would likely decrease since fewer cores are active. Overclocking might become slightly more feasible due to the reduced load, but overall gains would be minimal.

Typically, most jobs focus on one processor. Yet the actual issue is... why are you doing this?

This seems like a test or a trial. It's wise to explore it first. Let's see what happens and share our thoughts.

Purchase the cheapest Ryzen model with the fewest cores. The Ryzen 3 is a quad-core chip, but possibly some dual-core variants using SMT that you might disable.

Just curious about this. It seems you might be able to push all cores to their maximum without reaching the heat limit by disabling most of them. For those with first-gen Ryzen chips, a fake dual-core overclock could boost game performance. I currently have a Ryzen 5 1600 in one PC and a 2600x in another, so I'm planning to test it out.

I'll keep that in mind.
