How do you do that? Is it a setting in the bios? Or can it be done runtime? If so, how? It sounds interesting if I can run a beefy rig as a power efficient device, for always-on scenarios, and then boost it when I need.

On some Intel platforms, it's been settings in the BIOS. > It sounds interesting if I can run a beefy rig as a power efficient device, for always-on scenarios, and then boost it when I need. This is what the processor is doing internally anyways. It throttles voltage and frequency and gates cores based on demanded usage. Changing the TDP doesn't change the performance under a light-to-moderate workload scenario at all. Ryzen Master lets you change some of the tuning for the choices it makes about when and how aggressively to boost, though, too.
- Cloudef 6y agoRyzen Master doesnt seem to be available for linux so you end up with bunch of unnofficial hacks that may or may not work. I run sff setup myself, originally wanted to get 3600 but it was out of stock, and the next tdp friendly processor was 3700x.
- mlyle 6y agoThat's an annoyance, but on Linux you have infinite more control of thermal throttling and you can get whatever thermal behavior you want. Thermald has been really good on Intel, and now that Google contributed RAPL support you can get the same benefits on AMD-- pick exactly your power envelope and thermal limits.
