The tester Extreme Player from China carried out various benchmarks with a pre-production example of the Intel Core i9-13900K and compared them with the results of an Intel Core i9-12900KF. Games showed only a small difference in average FPS, but a very large one in minimum FPS.
Significantly higher min FPS with Raptor Lake
It becomes clear that the system with Raptor Lake is only a single-digit percentage faster than the Alder Lake computer in terms of maximum and average FPS. The minimum FPS, on the other hand, show much larger differences, depending on how hard the GPU, in this case a powerful GeForce RTX 3090 Ti, slows down.

In Full HD (1920×1080), the lead of the "Core i9-13900K" is around 28 percent. With increasing GPU load at a higher resolution, the plus is reduced to around 22 percent with WQHD (2560×1440) and just under 12 percent with 4K UHD (3840×2160).
With the average FPS, the plus is only between 3 and 7 percent, it looks similar with the maximum FPS with 3 to 6 percent.

The power consumption also increases
The fact that the additional performance will not be available for free is shown elsewhere: The maximum power consumption measured in the gaming tests is usually significantly higher for the Raptor Lake than for the predecessor.

Hardly any faster at the same rate
The Chinese tester has also published application benchmarks. In single-core tests, the Raptor Lake chip was usually about 10 percent ahead, in multi-core applications the lead grew to more than 40 percent in some cases. This largely corresponds to the expectations and also the observations in benchmarks with an engineering sample of the Core i5-13600K.

The additional performance per thread is likely to be achieved with Raptor Lake much above the maximum clock, which in this case (5.5 GHz vs. 5.2 GHz) is almost 6 percent higher. The big plus with multiple threads is the additional cores (24 vs. 16 in total).
