The video from Shamino78 channel shows a multithreaded benchmark (CPU Test 2 on Futuremark's 3DMark Vantage) experiencing OPS drops as processor "cores" are hotkeyed out on-the-fly.
When sextet CPUs become mainstream, the most obvious use of such a hotkey system is for users to rapidly switch "off" cores when applications with limited thread-scaling is used, before rapidly switching back to full multicore CPU processing. In applications where speed is secondary, it could also be used to put processor cores offline to save power.

VR Zone reports EVGA is working on several new overclocking features for its motherboards, including a feature that will enable users to rapidly switch cores off:
