Comparison of the two processors

In the comparison between the Intel Core i9-13900K and the Intel Core i9-13900KS, the two top processors in Intel's LGA 1700 socket compete against each other. First of all, you can see that these are almost identical CPUs. As a specially selected model, the Intel Core i9-13900KS can use slightly higher clock frequencies. The basic technical structure is identical for both processors.

Both the Intel Core i9-13900K and the Intel Core i9-13900KS have a total of 24 CPU cores. Both can process a maximum of 32 threads in parallel, which makes the CPUs particularly interesting for intensive applications. The processors are also impressive in newer computer games due to their high clock frequencies. However, if you only play computer games and use less demanding applications, you can find significantly cheaper processors.

However, if you regularly use the combined gaming and application performance, the Intel Core i9-13900K/S is a very good choice. Both processors can also be overclocked further using their standard clock speed.

The Intel Core i9-13900K has a base clock of 3.0 GHz, up to 5.8 GHz is possible in Turbo mode. With 3.2 GHz in the base and a whopping 6.0 GHz in turbo mode, the Intel Core i9-13900KS sets records here.

The 16 smaller E-cores (Gracemont architecture) clock at up to 2.2 GHz on the Intel Core i9-13900K, and here too the Intel Core i9-13900KS offers a clock frequency increased by 200 MHz. This is made possible by selecting the best chips that Intel sells in the Intel Core i9-13900KS.

Both processors have a simple iGPU (internal graphics) with the Intel UHD Graphics 770, which is sufficient to carry out simple work such as image and video playback. However, the iGPU is too slow for computer games.
