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 Ryzen 5 5600X is both the entry-level and best value for money 5000 series CPU. The 5600X is a hex-core 12 thread processor with a base clock speed of 3.7 GHz boosting to 4.6 GHz. It has 35 MB of cache and a TDP rating of 65W. A cooler is included in the MSRP of $300 USD, but cheap after-market coolers (such as the $20 GAMMAXX 400) are far more effective and therefore worth the upgrade. Notably, AMD’s new Zen 3 architecture has vastly improved single-core performance and lower memory latency, which leads to a significant effective speed advantage over its predecessor, the 3600X. Last year, AMD’s class-leading marketers secured significant sales of the 3000 series CPUs despite a 15% performance deficit against lower priced Intel parts. The games, specific scenes, software/hardware settings and choice of competing hardware were often cherry picked, undisclosed and inconsistent from one product to the next. Now that AMD have actually achieved both top tier performance and market share, their marketing machinery is focused on price hikes. Users that do not wish to pay a marketing premium should investigate Intel’s $175 USD 11400F, which, when paired with a 2060 Super, delivers higher EFps in four out of five of today’s most popular games. Allocating the savings to a higher tier GPU will result in a far superior gaming PC. [Nov '20 CPUPro]
