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 Intel G4560 is one of the first Pentium processors to feature Hyper-threading. This means that although the G4560 only has two physical processing cores, it is able to process four threads in parallel by sharing resources between the physical cores. This typically results in a 50% performance improvement over two physical cores alone. Comparing performance between the lowest spec Kaby Lake i3 7100 and the Pentium G4560 shows that in terms of both performance and specs, very little separates them (even virtualization technology VT-d is present on the Pentium). The Pentium does lack AVX 2.0 (Advanced Vector Instructions) and it trails the i3 7100 by 400 MHz (10%) but there is no longer a clear divide between Pentiums and Core i3s. Intel have achieved an almost continuous distribution of performance levels for each price point from the cheapest Pentium to the top end i7-7700K[Jan '17 CPUPro]
