After some update (Dell XPS) either from Microsoft or perhaps Dell, I noticed that my CPU was thermal throttling despite being only around 50C. I was using the Intel Extreme Tuning Utility to diagnose processor state. Digging in some more with the Throttle Stop app, for some reason my system was activating BD PROCHOT and throttling the CPU down to 0.8 GHz.

A quick search shows that this can be a bad sensor on the motherboard or something to do with the power supply being identified as non Dell (incorrectly in my case).
