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]

Intel’s Alder Lake i5-12400F offers six hyper-threaded performance cores at an MSRP of just $180 USD. This represents excellent value for consumers and, in particular, gamers. It has a boost frequency of 4.4 GHz, 18 MB of L3 cache and a TDP of 65W. The F-version of the CPU does not have integrated graphics, however this will be of little concern to gamers with discrete GPUs. Whilst Intel’s overclockable i5-12600K has four additional efficiency cores and offers around 12% more performance than the 12400F, it also costs around 50% more. The 12400F offers great value, but to achieve optimal performance the requisite B660 motherboard (which supports 3200+ RAM) is, at least for now, difficult to find at reasonable ($150 USD) prices. AMD’s top value hex-core Ryzen 5 5600X offers similar performance for 50% more money. Despite Intel’s price / performance lead, AMD’s prolific marketers (forums, youtube, reddit etc.) have historically outsold Intel whilst carrying a similar handicap. [Jan '22 CPUPro]
