Everyone knows that AMD and Intel have been battling for the CPU #1 spot for about 6 years straight now.
I used to prefer AMD over Intel server wise until about 8 months ago when AMD seemed to fall behind and Intel took over. Since intel makes motherboards and networking gear now... they have taken control of the server area. Of course their processors + motherboards + nics all in one machine are going use their resources to the max. AMD lost this edge since they only make the processor still... and havent expanded into other area's as of yet.
All of my servers are Intel processors.... but since I am a diehard fan of AMD all my home machines are AMD
