Also, keep in mind how little of the modern CPU&#x27;s die space is actually dedicated to the traditional cores. A quad-core skylake processor dedicates over half its space to things other than CPU cores [1], and that each core itself has a lot of space needed for paths that are always going to be used, like instruction decoding and storing the registers. So gating in a situation like this is only ever going to turn off a very small bit of the processor.<p>[1] <a href="http:&#x2F;&#x2F;www.techpowerup.com&#x2F;img&#x2F;15-08-18&#x2F;77a.jpg" rel="nofollow">http:&#x2F;&#x2F;www.techpowerup.com&#x2F;img&#x2F;15-08-18&#x2F;77a.jpg</a>
