It was tried before, with professional ARM server hardware: http://www.anandtech.com/show/8776/arm-challinging-intel-in-the-server-market-an-overview/9 http://www.anandtech.com/show/8776/arm-challinging-intel-in-... http://www.cnx-software.com/2014/10/26/applied-micro-x-gene-64-bit-arm-vs-intel-xeon-64-bit-x86-performance-and-power-usage/ http://www.cnx-software.com/2014/10/26/applied-micro-x-gene-... Spoiler: Intel still has the upper hand (for now), at least in perf-per-watt. Even the green500 (http://green500.org/news/green500-list-november-2015?q=lists/green201511 http://green500.org/news/green500-list-november-2015?q=lists... ) is dominated by Xeon-based clusters.

FWIW, the green500 list is dominated by accelerated systems, not pure Xeon clusters.

Bear in mind that the X-Gene is on a 35nm node and the A1100 is on 28nm, versus 14nm for Xeon-D. Applied Micro have announced a 16nm X-Gene 3 for this year via TSMC, and Qualcomm have a 14nm server processor in development via GlobalFoundries. We'd expect at least a 30% reduction in power from this change in process node. I think we could well see ARM server processors close the gap with Intel by the end of this year, which is an exciting prospect. IMO ARM's trump card is the diversity of their IP ecosystem. This has been integral to their success in the mobile SoC market and could become a genuine game-changer in the server market.

That's only true when the server is under load. 99% of servers worldwide are idling = ARM wins by a lot already today. There is going to be a leap in the cheap ARM board bus to something that supports USB3, then Intel will be gone from the server market in under a year.
