The hex-core i5-9600K is third in the latest line-up of Intel’s 9th generation of unlocked CPUs based on their refreshed Coffee Lake 14nm architecture. This round of releases also includes the 8 core, 8 thread i7-9700K and the flagship 8 core, 16 thread i9-9900K, out of which the 9600K at USD $280 is the value leader. The 9600K supersedes last year’s similarly priced 6 core 8600K and out of the box operates at higher clocks: base 3.7 GHz vs 3.6 GHz, all core 4.3 GHz vs 4.1 GHz and single 4.6 GHz vs 4.3 GHz. The 9600K has a TDP of 95W and will require a large cooler to match. The new Z390 or last years Z370 chipset with a BIOS update are both supported. Intensive multi-threaded task masters would do better to spend a similar amount on the Ryzen 7 2700X, where an extra USD $10 buys 2 more cores and 10 more threads resulting in multi-core benchmarks 70% higher than for the 9600K. However, for the vast majority of users that undertake up to quad-core workloads, the 9600K offers very reasonable bang for your buck, and when fully overclocked, almost second to none performance for gamers. [Oct '18 CPUPro]

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]
