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 1700 is the least powerful of three new Ryzen 7 CPUs. The 1700 model has base and turbo clocks of 3.0 and 3.7 GHz respectively. Both of its more expensive siblings, the 1700X and 1800X, have higher clocks but they also have TDPs of 95 watts whereas the 1700 is rated at just 65 watts. Comparing IPC between Ryzen and Kaby Lake shows that Kaby Lake leads by a maximum of 9% which is great news for workstation users as this allows the 1700 to beat Intel's 6850K in multi-core workloads at almost half the price. Although the 1700 has great IPC it's somewhat limited by its relatively low (by Kaby Lake standards) clock speed which holds it back a little in both gaming and desktop workloads. For multi-core workstation use, the Ryzen 7 1700 represents the best value for money we have ever seen. [Mar '17 CPUPro]
