Intel Core i7-8700K and Core i5-8400 Processor Review – Coffee Lake

Jump To:

Power Consumption

No review is complete without taking a look at power and the Intel Core i7-8700K did as we expected it would for a 95W TDP processor.

At idle the Intel Core i7-8700K Coffee Lake platform used 40.1 W at idle and that is impressive as includes the Gigabyte Z370 motherboard,  NVIDIA GeForce GTX 1080 FE video card, SATA III SSD and the Corsair Hydro water cooler. The 8400 basically idled at the same power, but used less at load. For example the 8700K processor topped out at 145W in Handbrake whereas the 8400 only reached 106 Watts on the same workload.
