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]

The Ryzen 7 5800X is one of four new processors from AMD’s latest range of Zen 3 CPUs. The new architecture is more power efficient than Zen 2 and also yields significant performance improvements. All four new CPUs have the ‘X’ nomenclature, indicating that they are tuned to their maximum clock speeds out-of-box. The 5800X has 8 cores and 16 threads with base/boost clock speeds of 3.8/4.7 GHz, 36 MB of cache and a 105W TDP. At $449 USD, the 5800X is relatively expensive, but it still offers far better value than the 5900X. A 500 series motherboard is recommended but the new Zen 3 CPUs will work with most 400 series motherboard following a BIOS update (expected in Q1 2021). At AMD’s launch presentation, they said they finally had the best CPUs for gaming. Our benchmarks show that the 5800X is comparable to Intel’s $175 USD 11400F. Gamers that do not wish to pay “marketing fees” can invest those savings in a better GPU which will produce an unquestionably faster gaming PC. [Nov '20 CPUPro]
