Kaby Lake i7 7700K is the next big thing when it comes to CPUs. With the new architecture just around the corner, the question is should you even upgrade? Here we have performance numbers comparing the Kaby Lake i7 7700K against the previous flagship 6700K. Both are unlocked SKUs and they can be overclocked. This should be interesting.
It seems that when it comes to gaming the Kaby Lake i7 7700K is faster but the difference is not all that significant. It is safe to say that if you did not have an FPS counter running on your screen you would not be able to tell the difference between the two CPUs.
Four games have been tested, Ashes of the Singularity, F1 2015, Metro: Last Light Redux, and The Talos Principle. All games showed similar results with the Kaby Lake i7 7700K having a slight edge on the previous generation CPU. But when it comes to head output, it is another story. It seems that the Kaby Lake i7 7700K gets much hotter when under load as compared to the 6700K.
This heat difference could be bad news for buyers as gamers are very conscious about such things. This also implies that the overall life of the CPU could also be affected. At stock speeds, the Kaby Lake i7 7700K hit 54C while the 6700 stayed at 34C. After overclocking the Kaby Lake i7 7700K hit 61C while the 6700 hit 48C. This is a significant difference.
Is it worth the upgrade then? Looking at the minor difference in performance and a major increase in heat output I would say that the new Kaby Lake i7 7700K is not worth it. You would be fine with the 6700. But if you must have the “latest and greatest” then why not? You can check out extensive benchmarks here.
