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]

MORE DETAILS

The i7-8700K is Intel’s latest, top of the range, 8th generation Coffee Lake processor. Like Kaby Lake and Sky Lake before that, Coffee Lake is based on Intel’s 14nm architecture which has been slightly optimized on each iteration. Following AMD’s modus operandi, Intel has upped the cores and threads across the range of their CPUs. In previous generations, a 6-core processor would have been a high-end desk-top (HEDT) processor, however the i7-8700K is the first Intel CPU with 6 cores and 12 threads to be classified (and priced) as a mainstream consumer processor. Specifically, the i7-8700K features a base clock speed of 3.7 GHz which boosts to 4.7 GHz (4.5 GHz for the previous generation i7-7700k), 12MB of smart (L3) cache and 2 channels of DDR4 RAM. The majority of the performance improvements over the 7th generation stem from the higher core count which results in a 50% increase in multi-core speed between the i7-7700k and i7-8700k. A new motherboard will need to be factored into the budget when upgrading to the 8700K as it requires a new Intel Z370 chipset which has supposedly been designed to better deliver power to CPUs with a greater number of cores. Also available in this latest release of CPUs is the 6 core 6 thread i5-8600k which is a more rational option (around $100 cheaper) for the vast majority of users that don’t require hyper-threading. Sandy bridge owners can finally justify an upgrade but with the next iteration of AMD's Zen architecture just around the corner the CPU market will be a lot faster moving now that Intel, once again, has to compete. [Sep '17 CPUPro]
