AnandTech's in-house overclocking guru Ian "Borandi" Cutress published an article last friday detailing the performance scaling when overclocking the Core i7 6700K to 4.8GHz. In the article, Ian has a look at what exactly is the benefit of overclocking Skylake in terms of computing performance. According Ian, 4600 MHz is a good target for any ambient overclock and 4800 MHz, as tested in the article, is the mark of a good sample.

The investigation leads the audience through a variety of benchmark such as Cinebench R15, Agisoft Photoscan, PovRay, winRAR, and so on. Next to the professional and office work suite, Ian also looks at the performance of the integrated graphics and that's where it gets interesting. When overclocking the CPU to 4.8GHz, the cpu cores use up all of the available power budget leaving the integrated graphics with little to no headroom. The initial performance indication shows a lower graphics performance when overclocking the CPU, but when the IGP clock frequency is fixed the results are on par with expectations.

Overall a 14% overclock of the CPU translated in an 11.7% performance increase in CPU benchmark tests. For more information and all the details, head over to AnandTech for the full article.
