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 9 5900X is second in AMD’s line-up of new Zen 3 CPUs. The 12-core hyper-threaded processor has base/boost clock speeds of 3.7/4.8 GHz, a 70 MB cache and a TDP of 105W. The 5900X took center stage in the 5000 series launch presentation where AMD gunned for Intel’s “best gaming CPU” crown. They showed the 5900X as being 26% better for gaming than the previous generation’s Ryzen 9 3900XT, attributing this to the new architecture’s faster single core speeds and lower latency. AMD also stated that the 5900X achieves, on average, 6.8% faster gaming performance than Intel’s 10-core i9-10900K. The details around AMD’s testing were not disclosed but it is safe to assume that 6.8% is the highest average lead that AMD are willing to stand by. Our benchmarks show that the 5900X’s slightly faster cores and the 10900K’s slightly lower memory latency balance out to yield similar performance. Whilst presenting their figures, AMD admitted that their 3000 series CPUs were far from “best for gaming” and conceded that the 10900K is approximately 19% faster than the 3900XT (our effective speed marks the gap at just 14%). Despite this clear performance deficiency, AMD supported 3000 series sales with an aggressive and successful marketing campaign to easily outsell Intel over the last 12 months. Given the real performance uplift observed in the 5000 series, and the absence of any meaningful marketing from Intel, we expect CPU sales to shift even further in AMD’s favour. Gamers that do not wish to pay “marketing fees” should investigate Intel’s $175 USD 11400F, the saved $660 USD would be far better spent on a higher tier GPU. [Nov '20 CPUPro]
