Revisiting the power consumption and efficiency of Intel's Core i7-8700K
Last week, I held off reporting estimated power efficiency numbers for AMD's Ryzen 7 family against those of Intel's Core i7-8700K in my Coffee Lake review. The power consumption numbers I observed for the Ryzen 7 CPUs during my tests were unusually (and improbably) high even though performance remained in line with expectations. I didn't track down the precise cause of the issue, but a reinstall of Windows on our AM4 test rig today fixed the problem. With everything in order again, I finally have load power numbers and estimated task energy calculations to share.
Blender is useful for estimating the amount of energy our CPUs consume over time because it's an unusually steady-state workload-power consumption varies little over the course of a render. We use the "bmw27" test file and monitor system power consumption using our trusty ...
