The maximum result in this parameter is 100 percent, which is the performance of the most powerful processor currently available. And it is clear that this is a server processor, on which no one will run games. Because this processor costs several tens of thousands of dollars. And if it seems to you that the selected CPU has a low game result, look at the FPS that it produces in real games in the summary table below.

The numbers in this table indicate the maximum FPS that was received on the device with the corresponding processor. Depending on the configuration of the computer (RAM size and Video Card) and graphics quality settings (Ultra, Medium, Normal), the results may differ quite significantly. We recommend that you better study the results of the Cinebench, GeekBench and Passmark becnmarks.
The tested computers not only did they have different amounts of RAM and different video cards. But users also tested them at different screen resolutions: FullHD, 2K or 4K. Therefore, the game benchmark data is approximate. But all video cards met the average system requirements of games. You will get more accurate information about how powerful the processor will be in games, if you get acquainted with the benchmarks that are made with the same video card that is installed in your computer.

To make a finishing resolution on which processor is better, you should also consider the generation of its core. It is clear that the newer the generation, the better the performance of the processor in games and benchmarks, as well as its energy efficiency. In this case the Core i9-12900H is more energy efficient than the Core i9-12900KF as it consumes less power: 125W vs. 45W. Power consumption is especially important for laptops. Also, when choosing a processor cooling system, it will be useful to know its TDP. You need to buy a cooler that has the TDP data specified in the specification was greater than the TDP of the compared processor.

Software benchmarks

Let's say you want to use the processor not only for gaming, but also for machine learning, video rendering or video editing, programming, streaming, then the main parameter for you is its performance in multi-threaded mode. In this mode, to reach maximum efficiency, the CPU includes all threads and cores that it has. You will learn this data from the benchmark tables below. Before using the data from these tests, be sure to check whether the program you are going to use on your computer supports multi-threaded mode. Because there are still many programs that can use only one core to work, and all the advantages of multi-core mode are unused.

Comparison of specifications

In the specification comparison table, the processor release date and overclocking capability will be the most helpful. The later the processor is released, the longer it will last in your computer. And the easier it will be to upgrade the system later. The same benefits from the presence of overclocking. When the processor can be overclocked, increasing its performance, then it will still be able to produce maximum FPS even in new games. The savings are obvious! Accordingly, you do not need to buy a new CPU to enjoy the games any longer.

Part number

In this comparison block, you should pay attention to the differences in clock speed and the number of cores. Here Core i9-12900KF is 2% better than Core i9-12900H in terms of CPU frequency. Another difference is that Core i9-12900KF has 2 more core than Core i9-12900H. Also keep in mind that high CPU frequency affects battery life through power consumption (relevant for laptops).

Result:
The number of parameters for which Intel Core i9-12900KF is better: 21
The number of parameters for which Intel Core i9-12900H is better: 11
Although it should be realized that all the number that you have looked at here do not mean that you should be guided entirely by them and trust a simple comparison of these numbers. Better to watch the testing video and read the reviews of of people who bought Intel Core i9-12900KF and Intel Core i9-12900H before making a decision which of the CPUs to buy for gaming.
