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 high-end hex core, 12 thread i7-8700 is second in Intel’s line up of 8th generation Coffee Lake CPUs that witnesses an increase in the number of cores at each SKU, as well as further refinement on the 14nm architecture as seen in the 6th and 7th generations. The i7-8700 features a TDP of 65W, 12MB of L3 Cache and 16 PCIe lanes. Although the 8700 has a base clock of 3.2 GHz it has an all core boost of 4.3 GHz and a single core boost of 4.6 GHz. These are unusually high clocks for a non-K SKU, Intel have historically clocked their non-K SKUs around 10% lower than the flagship K variants but with Coffee Lake, the 8700 is almost a match for a stock 8700K. Priced at $320, the i7-8700 offers exceptional single, quad and multi-core processing power to the mainstream market but unfortunately a new 300 series chipset will also need to be factored into the purchase. AMD’s comparably priced Ryzen 7 1700X is an 8 core 16 thread processor which is around 20% faster at multi-threaded tasks, but has around 20% slower single and quad core performance so the choice between these two processors is use case dependant but generally favours Intel for most desktop users whose workloads are typically single or dual core bound.  [Oct '17 CPUPro]
