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]

The Intel Core i5-4690K is the latest incremental upgrade to Intel's unlocked mid-range quad core family of processors. The 4690K replaces the 4670K. Comparing the 4690K and 4670K shows that little has changed. The two chips share identical architecture; in fact the only difference between them is a 100 MHz bump to both the base and turbo clocks. The 100 MHz bump translates to an insignificant 2.9% performance increase. In terms of outright performance the 4690K has an effective speed of 103 which thanks to its superb single and dual core performance, is 12% stronger than the average of the group leaders. Overall the 4690K brings nothing new to the table so owners of previous flagship i5's will gain little by upgrading but as a new purchase the 4690K is a strong contender for both power users and high end gamers. [Jul '14 CPUPro]
