power profile-W10, Balanced@2200(39c), Max@3950(40c)

Mon May 27, 2019 8:51 am

The "balanced" power profile has everything showing the cpu to be running at a 2200 speed. AND @ 39c.
The "max" 100% power profile seems to be false. Everything shows my cpu running at a full 3950 speed @ 40c.

(16 core Threadripper-gen1)

Obviously I'm missing something here. I only wish the cpu could go from idle to full tilt with only a 1 degree C increase.

thanks,

It's mostly idle and power-gated in either case, and temperature doesn't depend much on frequency (or voltage) because hardly anything is switching at that frequency (or on that voltage). Idle power draw is much more uncore-based, and the uncore is on a different clock.

Ok, thanks.
I've tried testing with both profiles and finding no real differences. I'll stay with the AMD Balanced profile.
Had read that some people do find a real improvement with the 100% profile.
