16 Cores, 24 Threads @3.2GHz, Alder Lake.
Release date: Q4 2021.

Average Bench: 117% (6th of 1363)

Based on 40,219 user benchmarks.  Device: BFEBFBFF00090672 Model: 12th Gen Intel(R) Core(TM) i9-12900K

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]

This one easily beat 5950X in terms of pure power. Massive gain in multi core performance make it best component for workstation. However, for gaming, 12700K would be better choice. Less TDP (which can spare more power for GPU) and less price tag.

Very Good Performance and even thermal efficiency , on a mid-range water cooler ( nzxt x53) , best value processor coming before the 12700k
