Intel Core i7-5960X 8-Core Haswell-E Processor Review

Power Consumption

Power efficiency remains important to PC users and Intel and AMD have both made great strides to improve power efficiencies. Today we will be looking at a few high-end desktop processors on our Watts Up Pro ES power data logger on the three platforms with each running Windows 8.1 on the balanced power option.

Benchmark Results: The Intel Core i7-5960X has much lower than anticipated power numbers, which is great. We double checked out power numbers on both the Watts Up Pro ES and Kill-A-Watt power meter because we thought something was wrong on the X99 platform. It looks like Intel Haswell-E has a very efficient idle power efficiency as we were right around 60 Watts at idle on the ASUS X99 Deluxe motherboard with UEFI 0601 along with a 16GB kit of DDR4 memory running at 1.2V and a GeForce GTX Titan video card with the latest GeForce 334.79 beta drivers along with the Corsair AX860i digital power supply. When running Prime 95 we hit 211 Watts and then when running 3DMark we hit 302 Watts. The Intel Core i7-4960X was run on the ASUS P9X79-E WS motherboard, which is known to be slightly power hungry with all the extras on it and idled at 99.8 Watts and hit 272 Watts in Prime 95 and 326 Watts in 3DMark.
