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 i7-6950X didn’t do that bad when it came to the power numbers, which is great. The new Intel Broadwell-E series appears to have a pretty efficient idle power efficiency as we were right around 77.3 Watts at idle on the ASUS X99 Deluxe II motherboard with UEFI 0601 along with a 16GB kit of DDR4 memory running at 1.2V and a GeForce GTX Titan video card and the Corsair AX860i digital power supply. When running Prime 95 we hit 219 Watts and then when running 3DMark we hit 321 Watts. Overclocking increased the voltage from 1.1V to ~1.25V, so the power consumption was up rather drastically for Prime95 and Handbrake where the CPU was put to full use. Futuremark 3DMark doesn’t use all 20 threads, so the power wasn’t up too much there.
