One of the only real issues with our dual E5-2670 v1 build was power consumption. Loading up both 8-core processors would push the total system power consumption to almost 350 watts. The newer E5-2630 v4 processors go a long way in rectifying that issue by reducing system consumption by 22% to 267 watts, which is only 20% more power than a single FX-8350 processor and of course there you have 8-cores whereas the Xeon system is playing with 20.

The E5-2630 v4 system consumed a similar level of power as the AMD FX-8350 rig while it sucked down 25% less watts than the older E5-2670 rig in the Hybrid x265 workload.

When testing with 7-Zip we see a massive 32% reduction in consumption for the dual Xeon E5-2630 v4 system compared to the E5-2670 v1 processors.
