The fact that the near three year old Intel i7-3960X still tops the speed charts reflects just how little competition there is in the CPU market. Intel have dominated for so long that there is simply no economic incentive to push the speed boundaries at anywhere nearly the pace of improvement we saw in previous years. The i7-3960X has 6 cores and 12 threads which is two cores more than the vast majority of Intel's other top end processors. The extra two cores explain why the 3960X still performs so well compared to the majority of the 3960X's newer siblings. This processor will offer little more than a far cheaper i3 to regular desktop users but for server orientated workloads it is still one of the best processors available. [Mar '14 CPUPro]

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]
