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 Ryzen 7 3700X hails from the middle of AMD’s latest range of 7nm silicon Zen 2 CPUs. The new processors are launched alongside the new X570 chipset, whilst still being backward compatible with 300 and 400 series motherboards. They are also PCIe 4.0 enabled, allowing double the data transfer speeds compared to PCIe 3.0. The 3700X has a boost clock of 4.4 GHz, 32 MB of L3 cache, supports 3200 MHz DDR4 memory and has a power draw of just 65W TDP. At an entry price of $329 USD, it is positioned to offer superb multi-core value for money. Out of the box, the 3700X, 3600X and 3600 achieve similar quad core speeds, which is important for gamers. In addition, the 3700X, with its 16 threads really excels at multi-core processing, achieving a 25% multi-core speed advantage over the 12 threaded 3600X. Early benchmarks rank the 3700X just a few places behind Intel’s 8-core, 16-thread i9 9900K with a 10% lower peak overclocked benchmark. However, it cannot be ignored that the 3700X is about $150 USD (32%) cheaper and includes a cooler unlike the 9900K. [Jul '19 CPUPro]
