Intel’s Core i7-9700K is an unlocked 9th generation CPU, released alongside the i5-9600K and the i9-9900K. The 9700K is an 8 core, 8 thread processor based on the third iteration of Intel’s 14nm Coffee Lake architecture, which sees an increase in the number of cores available to mainstream consumers, in line with AMD’s Ryzen 7 offerings. The 9700K features 12 MB of cache, a 95W TDP and Intel UHD graphics 630. And like the other 9th generation chips, it is compatible with Intel’s new Z390 chipset as well as last years Z370 chipset (with an updated BIOS). The 9700K has a base frequency of 3.6 GHz, rising to 4.6 GHz when all 8 cores are engaged and a single core boost frequency of 4.9 GHz (compared to 3.6 GHz, 4.7 GHz and 5.0 GHz for the flagship 9900K). This translates to similar single and quad core performance to the 9900K, but due to the higher number of threads, the 9900K has around a 50% higher multi-core benchmark than the 9700K. Currently most PC games do not engage more than 4 cores, so at $420 (15% cheaper than the 9900K), the 9700K offers better value for money to gamers. If instead, great multi-core performance is a necessity, at $290, the 8 core 16 thread Ryzen 7 2700X is a more prudent choice, with a 30% higher multi-core benchmark than the 9700K.  [Oct '18 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]
