The Core i7-7700K is Intel’s flagship Kaby Lake based CPU which is reported to have the same IPC as its predecessor, Skylake. Comparing the 7700K and 6700K shows that both average effective speed and peak overclocked speed are up by 7%. Most of the increase in average effective speed is explained by the 5% boost in base clocks from 4.0 to 4.2 GHz. The improved peak lab speed is attributable to a combination of better overclocking capacity and improvements in Intel’s speedshift technology which make the 7700K slightly more responsive. Kaby Lake also has marginally better HD 630 integrated graphics. The i7-7700K is priced similarly to the i7-6700K so for top end gaming and workstation builds, the 7700K is the clear choice for 2017. AMD’s Ryzen will release later this year so things could change at that time. [Jan '17 CPUPro]

The Core i5-7500 is not due for release until January 2017 but one of our users has submitted benchmarks for it already. We only have one sample so these benchmark results are obviously preliminary. Comparing the 7500 and 6500 shows that average effective speed is up by an impressive 15%. Although price details are not yet available the i5-7500 is likely to cost around $210 which would be in line with the prices for previous generations of this i5. We will revisit this summary when we have more samples. [Oct '16 CPUPro]
