This depends on whether you refer to "performance per watt" or "performance per purchase price".

Raw hash rates for different CPUs and GPUs can be found, for example, at http://monerobenchmarks.info/index.php

In terms of performance per watt (which is easiest to measure/calculate): - a Xeon Phi 7210 gets 2770H/s @ 225W, that's 12.3 H/J - a Dual AMD Epyc gets 3500H/s @ 335W, that's 10.4 H/J - a Dual Xeon E5-2699 gets 1910H/s @ 290(2x145)W, that's 6.4H/J - a Dual R9 Fury X gets 1890H/s @ 550W, that's only 3.4 H/J etc

  • a Xeon Phi 7210 gets 2770H/s @ 225W, that's 12.3 H/J
  • a Dual AMD Epyc gets 3500H/s @ 335W, that's 10.4 H/J
  • a Dual Xeon E5-2699 gets 1910H/s @ 290(2x145)W, that's 6.4H/J
  • a Dual R9 Fury X gets 1890H/s @ 550W, that's only 3.4 H/J

etc. From what I can gather, in terms of performance per watt (or, performance per power bill, if you want), the Xeon Phi is best.

In terms of purchase price, though, things may be quite a bit different...
