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 Intel Core i5-750 is a mid-range quad core, four thread desktop processor which is part of the Nehalem series launched in Q3 2009. Considering the age of this processor, its effective speed of 67 is damn impressive. It has a base frequency of 2.66 GHz, which boosts to 3.2 GHz turbo when under load and can be significantly extended beyond by overclocking. Combined with a decent graphics card, the i5-750 should give a reasonable gaming experience even by today’s standards. There are of course faster modern alternatives such as the i5-4690K, but if you already have the 750 with an older graphics card it's likely that your GPU will need updating before the CPU. Comparing the 750 and 4690K shows that the 4690K has an effective speed of 109 which is 62% faster than the now five years old i5-750. [Nov '14 CPUPro]
