A look beyond x86: OpenPOWER and AArch64

- Intel Xeon provides the best performance.<p>- Power consumption of Intel systems at off, idle and full power states are less then of ARM64 and POWER8 ones<p>- ARM 64-bit and Power 8 are currently providing a significantly lower performance &#x2F; Watt than Intel<p>Damn.

Little bit disappointed by the POWER8 data. I guess it would start paying bigger dividends in scale up systems, but the power and thermals are a little shocking - I think there may need to be some tuning and AFAICT Linux may not be running on bare metal.<p>Same for ARM, but I guess the sweet spot there is scale out.<p>Intel has been putting out amazing chips since Haswell.<p>We need the others to do well to keep them honest and innovative.

Will shortly be starting at a new company where I get to do things with OpenPOWER. I&#x27;ve never even touched a POWER architecture system apart from the occasional PowerPC Mac, so this will be an interesting learning experience for me.

X-Gene 1 is in ancient 40nm technology. Haswell is 2 generations ahead in 22nm Finfet technology.<p>The gap should close as the process technologies get closer.
