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]

The Ryzen 7 1800X is AMD's flagship Ryzen CPU. Clocked at 3.6 GHz with a turbo frequency of 4.0 GHz (stock) this chip offers a staggering level of multi-core performance. Comparing the 1800X with the Intel i7-6850K shows that the 1800X delivers 25% more multi-core throughput than its more expensive counterpart. Historically AMD's CPU architecture has had a much lower IPC than Intel's and consequently Intel have dominated the CPU market since 2009. Comparing IPC between Intel's Kaby Lake and Ryzen shows a maximum gap of just 9%. A very welcome shake-up of the CPU market will unfold as the remaining Ryzen 5 and Ryzen 3 models are rolled out. For now the 1800X offers workstation users similar processing power to a $1,000 i7-6900K at half the price. [Mar '17 CPUPro]
