Our Verdict on Each
The 13900KS delivers the highest stock clocks Intel has offered and excellent multi-thread performance, but its modest uplift over the 13900K and elevated power demands make it a niche choice for extreme enthusiasts rather than a mainstream recommendation.
Best for: You are an extreme enthusiast or overclocker chasing the highest stock clocks and do not mind the extra cost and cooling requirements.
Read the full reviewA very fast high-end desktop CPU that delivers elite single-thread and strong multi-thread performance, but at the cost of high power draw, demanding cooling, and a socket with no upgrade path beyond this generation.
Best for: Enthusiasts who want the fastest possible Intel platform for a mix of high-refresh gaming and content creation, and who already own or are willing to buy robust cooling and a high-end Z690/Z790 motherboard.
