The i7-8700K is Intel’s latest, top of the range, 8th generation Coffee Lake processor. Like Kaby Lake and Sky Lake before that, Coffee Lake is based on Intel’s 14nm architecture which has been slightly optimized on each iteration. Following AMD’s modus operandi, Intel has upped the cores and threads across the range of their CPUs. In previous generations, a 6-core processor would have been a high-end desk-top (HEDT) processor, however the i7-8700K is the first Intel CPU with 6 cores and 12 threads to be classified (and priced) as a mainstream consumer processor. Specifically, the i7-8700K features a base clock speed of 3.7 GHz which boosts to 4.7 GHz (4.5 GHz for the previous generation i7-7700k), 12MB of smart (L3) cache and 2 channels of DDR4 RAM. The majority of the performance improvements over the 7th generation stem from the higher core count which results in a 50% increase in multi-core speed between the i7-7700k and i7-8700k. A new motherboard will need to be factored into the budget when upgrading to the 8700K as it requires a new Intel Z370 chipset which has supposedly been designed to better deliver power to CPUs with a greater number of cores. Also available in this latest release of CPUs is the 6 core 6 thread i5-8600k which is a more rational option (around $100 cheaper) for the vast majority of users that don’t require hyper-threading. Sandy bridge owners can finally justify an upgrade but with the next iteration of AMD's Zen architecture just around the corner the CPU market will be a lot faster moving now that Intel, once again, has to compete. [Sep '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]
