Anybody seen these tests yet? I wonder how well it scales down and up in power. Downclocked some 5-600Mhz lower the 6700 65W part seems like a golden middle to me, but a detailed performance per watt chart would be nice to observe, nonetheless.

Yeah it is a really easy test to do as long as you have a kill-a-watt. Run prime95 and cpu-Z, set the clock using powercfg PROCTHROTTLEMAX, and read the meter, set the clock again, read the meter, etc. Takes like 5 minutes. I dont know why nobody does it.

Everybody talks about power efficiency, but no review web site has done it.

I don't want to buy Skylake-S just to run these tests myself.

I vaguely remember some bench sites doing power consumption @4.5, and it was using like 20w less than 4790k @4.5

Here's the power scaling on my Ivy Bridge CPU:

Frequency (performance) per watt, considering only the CPU


Frequency per watt, considering total system power


I'd love to see where the peak is on 14nm transistors, too.
