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]
