The 3930K has an outstanding multi-core performance profile, almost as good as you can buy at any budget, which considering its relatively reasonable price tag really make it stand out from the crowd. The reason for the extraordinary multi-core benchmark scores is down to the 3930K's six cores. Having six cores effectively results in a 50% lead over quad core cpus and a 200% percent lead over dual core cpu's. Typical desktop users rarely use more than two cores simultaneously thus rendering the additional four cores largely redundant for consumer use. In terms of regular use this CPU will offer virtually no better real world performance than the leaders in my Desktop CPU Group Test. For server orientated workloads the 3930K offers both outstanding performance and superb value for money. [Jun '13 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 (especially streamers) 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]
