So if you remove the "current/EDP" limiter and run a 20 thread torture test with small FFTs and all of the AVX options turned on, the i9 hits 302 watts! Amazingly, we can run that sustained with our...

As an experiment we tested to see how far a simple overclock on the i5 would go.

We ended up at 4.8GHz on all cores with an AVX load but the CPU was using 200W to achieve it!

It is true that we have this computer running 24×7 anyways, so the base power cost is kinda free.

We would have to factor in whole system power if we ran a bunch of other boxes.

We ran two benchmarks.

The first is with a power limit of 25W. The second is at 250W. We turned off the short term "turbo" thingie.

In all cases, using one worker yields the best throughput. We...
