Overclocking

The i7-8700K has plenty of strings to its bow when it comes to fiddling around in a non-stock scenario. As you can see at stock we get 4.4 GHz across the cores at a reasonable 1.2v vCore. If you’re willing to take a small hit in absolute clock speed you can get it to run – a six core hyperthreaded CPU remember – at a mere 1v for 4GHz of full fat goodness.

One of the newer Intel technologies is their Multicore enhancement which dispenses with the conventional wisdom of running one or two of the cores at a high clock speed whilst the rest lag behind like the fat asthmatic at school sports day, but instead it pushes all six of the cores up to a monster 4.7GHz. This is so impressive that we’ve added Multicore Enhancement to our standard stock and overclocked results in our graphs.

Lastly if you are willing to get your hands dirty then the thermal and power efficiency of the i7-8700K allows you to hit the magical 5GHz mark at just 1.28v. Five Gigahertz of hexcore loveliness? Don’t mind if we do.
