Gaming performance
Summary result of all game benchmarks.| Core i9-9900KF | 55% |
Core i7-7900X | 57% |
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.
List of other games in which CPU comparisons were performed: Resident Evil 7 Biohazard, League of Legends (LOL), Battlefield V, Metro Exodus, Hitman 3, The Witcher 3: Wild Hunt, DOTA 2A, PlayerUnknown's Battlegrounds (PUBG), Half-Life: Alyx, Control, Monster Hunter World, Horizon Zero Dawn, Shadow of the Tomb Raider, Ghostrunner, Forza Horizon 4, Microsoft Flight Simulator, Counter-Strike: Global Offensive (CS GO), NBA 2K20.
Gaming benchmark| Fortnite | 97.5 | 100.5 | | Valorant | 110.8 | 114.2 | | Cyberpunk 2077 | 62.0 | 63.9 | | Apex Legends | 104.1 | 107.3 | | Call of Duty Warzone | 83.1 | 85.6 | | Overwatch | 89.7 | 92.5 | | Red Dead Redemption 2 | 76.4 | 78.8 | | DOOM Eternal | 55.4 | 57.1 | | Warzone | 86.4 | 89.1 | | Assassin's Creed | 93.1 | 95.9 | | Valheim | 92.0 | 94.8 |
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 that were in the comparisons not only did they have different video cards and different amounts of RAM. But users also tested them at different screen resolutions: 2K, 4K or FullHD. 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.
Power consumption
| Core i9-9900KF | 48% |
Core i7-7900X | 32% |
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 i9-9900KF is more energy efficient than the Core i7-7900X as it consumes less power: 95W vs. 140W. 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 benchmarksIf you plan to use the processor not only for gaming, but also for streaming, programming, machine learning, video rendering or video editing, then first of all you need to pay attention to the performance in multi-threaded mode. In this mode, the CPU uses all cores and threads that it has to the maximum to reach maximum efficiency. 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 run, and all the advantages of multi-core mode are unused.

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