Notes

The Core i9-12900KS is Intel's special edition Alder Lake processor featuring 16 cores (8 P-cores, 8 E-cores) with boost speeds up to 5.5 GHz, higher than the standard 12900K. This binned CPU represents the peak of 12th gen performance, offering enhanced clock speeds for enthusiasts seeking maximum Alder Lake capability. The higher frequencies provide advantages in gaming and lightly-threaded workloads while maintaining strong multi-core performance. Requires robust cooling due to increased power demands. Ideal for enthusiasts wanting the fastest possible 12th gen processor, though often better value can be found in newer generations at similar price points.
