We did not test any of those. We don't actually test PhpStorm on certain processors. You can check benchmarks of these processors and pick the fastest one, that's the only advice we can give.
the question is not even specifically in these processors, but will phpstorm work fully on eight cores and eight threads? or it is enough to take a processor with two cores and four threads, because phpstorm does not yet fully use all processor threads?
or amd fx8350 (eight-core)?

PhpStorm runs on Java8 which utilizes hyperthreading + according to our old threads (from 2010) we've been already using hyperthreading by that time.
So all the threads should be used in theory. Unfortunately no tests were conducted on this matter.
