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 Raptor Lake Intel i5-13400F ($200 USD, cooler included) paired with a B660/B760 motherboard ($150 USD) and 2x8 GB DDR4 3600 RAM ($50 USD) offers good value for money to mid-range gamers. The 13400F has around 5% higher single-core and 35% higher multi-core performance than its predecessor. Although both processors feature the same Golden Cove p-cores, the 13400F has four additional energy efficient e-cores which account for the improvement in multi-core performance. The 13400F offers comparable gaming and better multi-core performance than AMD's 7600X but at a lower price and without the need for an aftermarket cooler, DDR5 memory and an expensive motherboard. Since Intel don’t care for long term relationships with PC hardware influencers, for product launches, they often end up sponsoring influencers that are mostly funded by AMD. As a result, Intel rarely get positive marketing coverage beyond launch, and their products remain relatively under priced compared to AMD. When paired with a DDR4 motherboard the 13100F/13400F CPUs (at MSRP) offer unbeatable/good value to entry/mid level PC gamers. High end gamers should investigate the 13600K, which thanks to both higher clocks and higher IPC (Raptor Cove), is around 15% faster than the 13400F. [Jan '23 CPUPro]
