Though he declined to discuss specific customers, Inglis said ARM-based chips will appear first in machines that are used to support basic access to websites, then graduate into more powerful systems.
“As we move forward into 2014 you’ll begin to see systems emerging,” he said.
Inglis is an executive at ARM, this is more PR from them. And, the kicker is, the year they have mentioned about "systems emerging" is 2014 !!! Sure, Intel is going to remain where it is in power management!! Intel will probably be at sub10nm with Near Threshold Voltage technologies long before ARM-based servers "emerge".
HP, on its part, tries to straddle across multiple potential technologies. Unfortunately, it is a risk-aversion strategy on the part of HP, and it hasn't served them well in the past. If I were Calxeda, HP is the last company I would want to partner with.
I don't understand how HP using ARM-based chips would be challenging Intel. HP has the right to put in any chip they want and using ARM is not challenging Intel. Perhaps they are challenging the bribes?
