The suffix \"KF\" in the model name indicates that the chip lacks integrated graphics.When overclocking the CPU to 6.2GHz, a Corsair iCUE H150I RGB Elite liquid cooling system was used as well as a Thermal Grizzly contact frame to protect against socket and poor waterblock contact with the chip cover.
The test system also contained an ASUS ROG Maximus Z690 APEX motherboard, a GeForce RTX 4090 graphics gas pedal and G.Skill DDR5-6000 memory modules with CL36 delays.

In the single-core benchmark Cinebench R23, the processor showed a score of 2352 points after overclocking.
This allowed it to rank 13th in HWBOT's single-core performance ranking.
The user also reported that the processor scored 41,940 points in the multi-core performance test.

The Core i9-13900KF was overclocked at 1.474V.
The enthusiast also added that he was limited in time, so he has not yet conducted thorough tests on the processor.
At the same time, standard overclocking profiles of ASUS ROG Maximus Z690 APEX motherboard were used in the experiment.
