"The issue that ARM faces is not so much hardware as software, although there are some hardware availability issues from both Cavium and Applied Micro, the two dominant suppliers of ARM server chips these days. They are shipping their respective ThunderX and X-Gene products now and are working on next-generation follow-ons, which will offer better performance and performance per watt, but Intel has kept the pedal to the metal with Xeons, too. Tease says that operating systems, compilers, and management tools all need to be optimized further to run better on ARM chips. “We are not seeing the performance per watt benefits that we had hoped to see with ARM at this point, but as the community builds out this ecosystem and the compilers get better, in the long term, I think ARM is going to be a player. It might take us a while to get there. It is exciting, even if it is not just around the corner.”"
