Intel’s 16-core flagship Alder Lake i9-12900K processor delivers a staggering performance improvement over it's predecessor (+70% 64-core). It features a new hybrid architecture which combines eight hyper-threaded performance cores with eight efficiency cores for a total of 24 threads. Alder Lake CPUs will require a new Z690 chipset which supports DDR5 memory and PCIe 5.0. At an MRSP of $590 USD, the i9-12900K is aimed at power users who demand the best of the best. That said, Intel’s 10-core 12600K matches the 12900K’s performance for the majority of consumer use cases at a 50% price discount. [Nov '21 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]
