Power Determinism Mode Still Proves Beneficial For AMD EPYC 9005 Performance

So the one labeled "performance" has better power consumption and the one labeled "power" has better performance? Got it.

How are you monitoring AMD power consumption on Linux? I thought AMD kicked out all the linux drivers to check it and effectively forbade us from monitoring power on their CPUs and GPUs.

Is this just from the wall/12v rails or is there another updated power monitoring driver for AMD CPUs?

Phoronix: Power Determinism Mode Still Proves Beneficial For AMD EPYC 9005 Performance

Typically in my launch-day Linux reviews of new AMD EPYC processors I try to include results both of the performance determinism (default) and power determinism modes available with these server processors since opting in to the power determinism mode can allow for additional performance uplift at the cost of slightly higher power costs. With the AMD EPYC 9575F / 9755 / 9965 benchmarks and review I didn't have a chance to complete all of the power determinism runs in time for that review, but for those curious about power vs. performance determinism modes with the 5th Gen AMD EPYC "Turin" processors, here is a side-by-side comparison.
