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]

MORE DETAILS

The Intel Core i5-4670K is the latest middle tier desktop processor from the fourth generation of Intel's Core range codenamed "Haswell". In terms of raw performance this processor slightly bests its predecessor the 3570K achieving approximately 10% higher server benchmark scores. In terms of real world performance the single core improvements are more relevant as more than two cores are rarely used for most typical consumer tasks and these have also improved by around 10% over the 3570K. It's not all good news though as the price increase of 14% more than offsets the performance improvements. This processor currently represents approximately the same value for money as its predecessor, the i5-3570K. [Jun '13 CPUPro]
