<br>
Intel wins on single thread performance and energy efficiency, AMD on cost efficiency - the latter may be eaten up by energy cost though.<br>
Functional differences exist, if you want to take advantage of the latest CPU extensions (AVX, AESNI, TSX,...) otherwise not. <br>
<br>
ARM(v8) may be an interesting option in the future for scale - out workloads (moderate single thread performance requirement with high energy efficiency). Note that a lot of commercial software is not (yet?) avail for ARM - for open src you don't have that issue. <br>
<br>
HTH, <br>
