The unlocked hex-core i5-8600K from Intel’s latest Coffee Lake generation of processors is the new flagship of the i5 series, succeeding the Kaby Lake quad-core i5-7600K. The 8th generation of processors brings the largest performance uplift since Sandy Bridge by adding more cores at each of the i3, i5 and i7 product lines. Like the other Coffee Lake processors, the i5-8600K is built upon optimized 14nm architecture, marginally improved upon from Kaby Lake and Skylake. The 8600K has a 95W TDP and a nominal stock clock of 3.6 GHz, which boosts to 4.1 GHz for all six cores, 4.2 GHz for dual/quad and 4.3 GHz for single core. Early benchmarks put the i5-8600K’s effective speed 15% ahead of the i5-7600K. A 50% increase in multi-core speed is explained by two additional cores and thanks to the quad-core clock bump from 4 GHz on the 7600K to 4.2 GHz on the 8600K there is also an additional 5% performance boost across all workloads. All Coffee Lake processors require a 300-series chipset, making a straight CPU upgrade unfeasible despite sharing the same socket as their Z270 predecessors. Even though most games still use less than 4 cores simultaneously, the i5-8600K is a great choice for gamers but for $80 less, the 8350K which is faster than last years 7600K and only marginally weaker for gaming than the 8600K is certainly well worth considering as well. [Oct '17 CPUPro]

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]
