It looks like the guys over at Tom’s hardware have got their hands on Intel’s new “Kaby Lake” Core i7-7700K. Their sample was not marked as an engineering sample, but they cannot confirm that it is indeed a retail part. They’ve taken the chip through a series of benchmarks at both stock and overclocked settings. Since retail Z270 motherboards are not available yet they did their testing on a Gigabyte GA-Z170X-Ultra Gaming with updated firmware.
The stock speeds of the chip they have are 4.20 GHz base and a 4.50 MHz max turbo boost with a TDP of 95W. Their benchmarks are more or less in line with what we expected. When it comes to overclocking they were able to bring the chip up to 4.8 GHz at 1.3V VCore, using the same settings the current i7-6700K was only able to get up to 4.6 GHz.
Kaby Lake is to bring with it HEVC and VP9 8/10-bit encode/decode and other possible features we may not yet know of, but improved clock speed is the main improvement. The core micro architecture has not been changed between Skylake and Kaby Lake. Please keep in mind that this is a pre-release test on a motherboard that might not unlock all of the features of the and full potential of the i7-7700K.
