The lineup begins with the Core i5-12600KF boxed processor at $261.77, a 6+4 core (P+E), 16-thread processor with 20 MB of L3 cache, and 4.90 GHz maximum boost frequency for the P cores. As a "KF" SKU, it lacks an iGPU. The i5-12600K, which has the same specs and an iGPU on top, is priced at $295.49.
The Core i7-12700KF and i7-12700K are 8+4 core (P+E), 20-thread chips with 25 MB of cache, and 5.00 GHz boost frequency. The two are differentiated by iGPU. The i7-12700KF is priced at $395.61, and the i7-12700K at $422.17. Leading the pack, are the Core i9-12900K and i9-12900KF, which max out the silicon, with 8+8 (P+E) core, 24-thread, and 30 MB of cache. These boost up to 5.20 GHz, but we've heard rumors of the Thermal Velocity Boost feature driving frequencies beyond this. The i9-12900KF is priced at $578.13, while the i9-12900K goes for $604.99.
