For the maximum in this test, the results of the most powerful processor in the site database are taken. And it is clear that this is a server processor, on which no one will play games. Because this processor costs several tens of thousands of dollars. Therefore, if you think that the selected CPU has a low game result, just look at the FPS that it produces in real games in the summary table below.
List of other games in which processors were compared: Counter-Strike: Global Offensive (CS GO), Metro Exodus, League of Legends (LOL), DOTA 2A, Ghostrunner, Half-Life: Alyx, Forza Horizon 4, The Witcher 3: Wild Hunt, Monster Hunter World, Horizon Zero Dawn, PlayerUnknown's Battlegrounds (PUBG), Shadow of the Tomb Raider, Control, NBA 2K20, Microsoft Flight Simulator, Resident Evil 7 Biohazard, Battlefield V, Hitman 3.

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 computers participating in the comparing not only were the equipped with different amounts of RAM and different video cards. But users also tested them at different screen resolutions: 2K, FullHD or 4K. So the game benchmark data is approximate. But all video cards met the average system requirements of games. To be sure exactly how much performance 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. The newer the processor generation, the better its performance in games and benchmarks, as well as its energy efficiency. In this case the Ryzen 5 PRO 5645 is more energy efficient than the Core i9-9900K as it consumes less power: 65W vs. 95W. Power consumption is particularly important for laptops. And TDP should be taken into account when choosing a processor cooling system. It is necessary to count so that the TDP data specified in the cooler specification is greater than the TDP of the compared processor.

Software benchmarks

For example you plan to use the processor not only for gaming, but also for video editing or video rendering, machine learning, programming, streaming, then the main parameter for you is its performance in multi-threaded mode. In this mode, the CPU turns on all cores and threads that it has to the maximum to achieve maximum efficiency. You will learn this data from the benchmark tables below. Before you take into account the data from these tests, be sure to make sure that the program that you are going to use on your computer can work in multi-threaded mode. Since there are still many programs that can use only one core to work, and all the benefit 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 newer the processor, the longer it will last you. 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 continue to maintain maximum FPS even in the newest games. The savings are obvious! Accordingly, you do not need to buy a new CPU to enjoy the games any longer.

In this comparison block, you should pay attention to the differences in clock speed and the number of cores. Here Ryzen 5 PRO 5645 is 2% better than Core i9-9900K in terms of CPU frequency. Another difference is that Core i9-9900K has 2 more core than Ryzen 5 PRO 5645. Also keep in mind that high CPU frequency affects battery life through power consumption (relevant for laptops).

Result:
The number of parameters for which AMD Ryzen 5 PRO 5645 is better: 14
The number of parameters for which Intel Core i9-9900K is better: 23
Although it should be understood that all the figures in the article above do not mean that taking them into account you should entirely trust a simple quantitative comparison. Better to watch the video tests and read the opinion of real owners of AMD Ryzen 5 PRO 5645 and Intel Core i9-9900K before deciding which of the CPUs to buy for gaming.
