About 3 sales a week in the four weeks to 20 Oct.
Before you buy or sell a used i9-12900K
With an 8P+8E sixteen-core, twenty-four-thread layout and 5.2 GHz boost, the i9-12900K sits between the graphics-free i9-12900KF and the higher-clocked i9-12900KS. Those variants, along with the 65W i9-12900, are tracked as separate parts.
Despite the 125W base TDP, turbo draw reaches 241W and no cooler comes in the decorative wafer retail box. Pair it with a 280mm or 360mm liquid cooler on an LGA1700 DDR4 or DDR5 motherboard.
