The current Core architecture has been around for 6-7 years and has lots of time for software optimisations to be done for it. Ryzen has been out for 1 month... I remember back in the v26.xx days,...

@LaurV... thanks for the comparison benchmark.

So for the case of both systems running on 8 physical cores, it's 7.136ms for the i7-6950X @ 3.0GHz vs 12.69ms for the Ryzen 1700 @ 3.3GHz. Looks...

Here's the permutation of results for the various number of cores / workers. It takes a long time to run, so I've only tested the 1024K and 8192K FFTs:

What type of performance are you trying to measure? Programmes like P95 are built with a singular purpose in mind. They are very narrow and may not be a good indicator of real world performance.

Does your system increase the voltage by +0.1V when AVX is in use? In which case your 1.2V could actually be 1.3V instead?
