The Phoronix Test Suite monitors the overall AC system power consumption using a USB-based WattsUp Pro power meter. Here's a look at a few of the test runs while measuring the power use on each of the systems and then also calculating the performance-per-Watt.

While running John The Ripper, the average power draw of the Core i7 5960X system overall was 166 Watts and peaked at 196 Watts, which was actually lower than the IvyBridge-E i7-4960X that had an average of 207 Watts and a peak of 231 Watts. The i7-5960X even ended up running better than the FX-8370 and of course much better than the AMD FX-9590 with its 220 Watt TDP.

When calculating the performance-per-Watt, the i7-5960X was out slightly ahead of the Haswell-based Core i7 4770K/4790K processors and a big step ahead of the previous generation Ivy Bridge Extreme setup. The AMD CPUs didn't come close to threatening the power efficiency of the i7-5960X Haswell-E platform.

The C-Ray results were also excellent.
