I'd be curious to see power consumption. SHA (and AES) are usually available as what amounts to an ASIC built into the processor, while this requires a lot more work to be done with vector instructions.
That's not how it works on modern CPUs. Power draw at "100%" utilization can vary widely depending on what part of the core is being utilized. The SIMD units are typically the most power hungry part of the CPU by a large margin so just because a job finishes in less time doesn't mean total energy is necessarily lower.
The AES and SHA instructions are part of the vector units so their energy will be similar to other integer SIMD instructions. The overhead of issuing the instruction is higher than the work that it does so the details don't matter.
this is less precise than the perf numbers as I don't really have a way to measure power directly, but with rerunning the benchmarks above locked to a cpu core, it boosted ~the same level for all 3 commands (about 5.5ghz), so should be ~the same power usage.
