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 latest 10-core i5-12600K Alder Lake desktop processor offers an impressive 50% 64-core performance improvement over it's predecessor. The 12600K combines six hyper-threaded Golden Cove P-cores with clock speeds up to 4.9 GHz and four energy efficient Gracemont E-cores for a total of 16 threads. Alder Lake CPUs have a new LGA 1700 socket which requires new cooler brackets and a new Z690 motherboard. Z690 brings several new features including PCIe 5.0 and DDR5 memory. Most Z690 boards will ship in both DDR4 and DDR5 variants. DDR4 is likely the better option, at least until DDR5 prices settle. With an MRSP of just $290 USD, the 12600K is both cheaper and faster than the competition in both single and, notably, multi-core performance. As a result, even AMD's prolific marketing infrastructure (youtube, reddit, forums etc.) will struggle to drive sales, at least until Zen 4 launches (est. late 2022). In the meantime, Intel's i5-12600K is the obvious choice for consumers that do not wish to pay over the odds for almost unparalleled performance in the majority of workloads including gaming. That said, gamers that already own a K series CPU from the 8th gen. or higher will see limited gains in the majority of titles when paired with a 3060 (or lower) tier GPU. In some cases (e.g. PUBG or Overwatch) gamers will see fewer frame drops by disabling the E-Cores all together. If recent history is a guide, stock levels at MSRP are likely to deplete rapidly. [Nov '21 CPUPro]
