• Base Clock Speed of 3.0 GHz and Boost Clock Speed of 5.7 GHz: The 13900KS boasts a higher boost clock speed of 5.7 GHz, allowing it to reach higher performance levels under demanding workloads.
• 150W Base Power and 253W Maximum Turbo Power: The 13900KS requires slightly more power than the 13900K, necessitating a more robust cooling solution.
• Same L3 Cache as the 13900K: The 13900KS retains the 36MB L3 cache of the 13900K, providing efficient data storage and retrieval.

Performance Comparison: A Head-to-Head Matchup

Both the 13900K and 13900KS deliver exceptional performance, but the 13900KS edges out its sibling in most benchmarks.
Gaming Performance:
In gaming, both CPUs offer incredible performance, capable of pushing frame rates to the limits of even the most demanding graphics cards. The 13900KS typically delivers a slight edge in performance, thanks to its higher boost clock speed, resulting in a few extra frames per second in some games. However, the difference in gaming performance is often marginal, and both CPUs are more than capable of delivering smooth and immersive gaming experiences.
Productivity and Multi-Tasking:
Both CPUs are excellent for demanding productivity tasks like video editing, 3D rendering, and software development. The 13900KS, with its higher boost clock speed, can provide a noticeable performance advantage in multi-threaded workloads. However, the 13900K is still a very capable processor and can handle most productivity tasks with ease.
Power Consumption and Heat Output:
Due to its higher boost clock speed, the 13900KS consumes slightly more power and generates more heat than the 13900K. Therefore, a more robust cooling solution is recommended for the 13900KS to maintain optimal performance and prevent thermal throttling.
