Energy-efficient does not mean low power. It means a better quotient of MIPS or GFLOPS per power unit used. Those numbers are published if the processors in question ran LINPACK or for I/O, a similar test.

The A57 is supposed to deliver 3x the performance of a15. Of course that means it would still need more cores than Xeon Phi. Interconnecting the cores also takes energy. I think it remains to be seen which is better in terms of performance/W.

What are the numbers? Anything publicly available?

Nvidia is being very quiet lately about its plans for a supercomputer-class chip using 64-bit ARM cores and its graphics processors. But they have the chops to create a shift here.

The ARM A57 is indeed a low power chip, but its' performance/watt is way lower than others.

“There’s a need for energy efficient architectures,” .... Hmm, with all the hype around ARM maybe we might see A57/X-Gene in this space sometime this decade?
