AVX / AVX2 / AVX-512 Performance + Power On Intel Rocket Lake

This is a look at the overall CPU power consumption across the span of the workloads tested. On average the CPU power consumption was 17% higher with the AVX-512 test run while the peak CPU power consumption reported by Intel's RAPL interfaces spiked from 265 Watts to 292 Watts, a 10% increase.

The increased power consumption did translate to higher temperatures.

That's the quick look at AVX-512 performance with Rocket Lake / i9-11900K. More benchmarks of Rocket Lake still forthcoming on Phoronix looking at different areas under Linux and other platforms like the BSDs.
