I don't understand the surprise of the power use of the 9900K at 5GHz blender. The 8086K review already shows that at 5GHz, it uses over 150W :
So an equally overclocked 8-core using 1/3rd more power isn't too surprising.
because this is stock 4.7ghz, not an overclock sir. 5ghz is only the single/dual threaded turbo clock, not the all-core.
