srsRAN performance on Intel vs AMD

[JonPichel]

Hello everyone,

I've been looking at the source code of the project and I found that you use MKL (https://github.com/srsran/srsRAN_4G/blob/master/cmake/modules/FindMKL.cmake). My question is if this translates into a noticeable difference in performance when using AMD vs using Intel CPUs. Should I prefer an Intel CPU over an AMD CPU with similar characteristics when choosing a machine to run this software?

In general, there is no significant performance improvement using KML. In fact libfftw performs very well on both platforms so there is no reason to worry.
