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 AMD Ryzen 7 1700X isn't due for release until next week but two of our users has already submitted benchmarks. Comparing the quad and single core scores from our samples shows a relative 4.3% boost on the single core score so it’s possible that turbo wasn’t fully engaged (12% turbo boost expected). These preliminary results are seriously impressive as they put Zen’s IPC between 0% and 9% below Intel’s Kaby Lake. Even in the worst case scenario these results are still impressive. Comparing Intel’s $1,000 6900K and the 1700X shows that AMD delivers comparable performance for half the price! A shake-up of the CPU market will unfold as Zen rolls out. If Ryzen CPUs can overclock to 4.6+ GHz they will likely dominate the entire market putting a very welcome end to the monotonous tick-tock of recent years. [Feb '17 CPUPro]
