Turning a Ryzen CPU into a single core

What would happen if you went into AMD's Ryzen Master software and disabled all but one of the cpu cores? I'm guessing performance would take a massive hit, even in simple tasks like browsing the internet and word processing, but would there be less heat output? Could you overclock further because it's just one core? I'm really curious.

Most common tasks are single core oriented.

But the real question here is.. why do you want to this?

I'm guessing this is just an experiment. Therefore, why not try it? Go find out and tell us, I'm curious.

Buy the lowest end Ryzen with least cores. Ryzen 3 is quad core iirc. Maybe there are even some dual cores with SMT which you can turn off.

But why? You do know that there still needs to be a good balance between speed and cores for good performance and heat, right?

Purely out of curiosity. I was thinking that with the majority of cores disabled, you may be able to overclock all the way to the power limit, without hitting the thermal threshold. Those who have 1st gen ryzen chips could potentially attain better game performance by using a faux "dual core" overclocked CPU... Right now I have a Ryzen 5 1600 in one PC and a 2600x in another PC, so I'm going to try it out and see what happens.
