What do your apps need? • Lots of memory?
Perhaps Power9 or Naples with 8 memory channels? Also, Cavium ThunderX2. • More memory bandwidth? Same as above. • Max single thread performance? Intel or Power9? • Are your apps GPU enabled? If not, do you have budget/time/expertise to do the work? If not, then stick with CPUs. • Need lots of PCIe for accelerators, SSDs, NICs? Naples. • Interconnect? If Intel, either of the above. Does OPA work with Naples (I don't know)? If Power/ARM and possibly Naples, then IB. Sorry to give the default computer science answer of "It depends."
