Intel is touting its flagship Alder Lake processor as the best for gaming, with its own in-house benchmark testing. All the specs for each desktop CPU can be viewed in the image below. Other processors in the Alder Lake line include the $564 Core i9-12900KF, which includes the same processor cores and threads as the i9-12900K. The flagship Alder Lake processor has more cores than the flagship Rocket Lake which had 8 cores and 16 threads, but slightly higher boost clock speeds (5.3GHz).

Leading the 12th Gen line is the $589 Core i9-12900K, which features 16 cores (8 P-cores and 8 E-cores), 24 processor threads, and boosted clock speeds up to 5.2GHz. Intel's 12th Gen Alder Lake Desktop CPU lineup. Unfortunately, these new processors won’t work with Z590 or older motherboards as the new chips use an LGA 1700 socket unlike the LGA 1200 socket found on the 11th gen (Rocket Lake) and 10th gen (Comet Lake) Intel Core processors. The Alder Lake desktop CPUs also introduce support for DDR5 RAM, PCIe Gen 5, Thunderbolt 4, and Wi-Fi 6E on the new Z690 chipset.
