The Core i7-7700K is Intel’s flagship Kaby Lake based CPU which is reported to have the same IPC as its predecessor, Skylake. Comparing the 7700K and 6700K shows that both average effective speed and peak overclocked speed are up by 7%. Most of the increase in average effective speed is explained by the 5% boost in base clocks from 4.0 to 4.2 GHz. The improved peak lab speed is attributable to a combination of better overclocking capacity and improvements in Intel’s speedshift technology which make the 7700K slightly more responsive. Kaby Lake also has marginally better HD 630 integrated graphics. The i7-7700K is priced similarly to the i7-6700K so for top end gaming and workstation builds, the 7700K is the clear choice for 2017. AMD’s Ryzen will release later this year so things could change at that time. [Jan '17 CPUPro]

The 8 core, 16 thread 2700X is AMD’s second generation Ryzen 7 flagship following in the wake of the Ryzen 7 1800X which continues to offer excellent multi-core value for money. This new Pinnacle Ridge processor features the Zen+ architecture with 12nm lithography compared to 14nm previously. Whilst there is no increase in the number of cores, the stock base / boost clocks appear to have received a bump up to 3.7 / 4.3 GHz from 3.6 / 4.0 GHz. The 2700X is compatible with both the new 400 series and 300 series of motherboards. Early benchmarks indicate that the 2700X has a slightly greater effective speed than the 1800X, although further benchmarks are necessary to quantify this. The expected launch price of $329 includes a Wraith Prism cooler and is in the same price bracket as the 1800X and Intel’s Coffee Lake i7-8700K. Whilst the 6 core, 12 thread 8700K beats the 2700X in single and quad core performance by about 10%, the 2700X wins on multi-core workloads. PC gaming and desktop performance is generally governed by six or less cores but the 2700X offers value for money to workstation users. [Apr '18 CPUPro]
