Our Verdict on Each
A formidable processor that excels in both multi-threaded workloads and high-refresh-rate gaming, though its high power draw and thermal output demand robust cooling and a premium power supply.
Best for: Building a new high-end desktop for gaming and content creation where cost is not the primary constraint, and the user is prepared to invest in premium cooling and power delivery.
Read the full reviewThe 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.
