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. And if it seems to you that the selected CPU has a small game result, look at the FPS that it produces in real games in the final table below.
List of less popular games in which processors were compared: Resident Evil 7 Biohazard, PlayerUnknown's Battlegrounds (PUBG), Monster Hunter World, Hitman 3, Half-Life: Alyx, DOTA 2A, Forza Horizon 4, Battlefield V, League of Legends (LOL), Microsoft Flight Simulator, Metro Exodus, Control, NBA 2K20, Counter-Strike: Global Offensive (CS GO), Shadow of the Tomb Raider, Horizon Zero Dawn, The Witcher 3: Wild Hunt, Ghostrunner.
Gaming benchmark| Fortnite | 100.8 | 106.1 | | Valorant | 114.6 | 120.6 | | Cyberpunk 2077 | 64.2 | 67.5 | | Apex Legends | 107.7 | 113.3 | | Call of Duty Warzone | 85.9 | 90.4 | | Overwatch | 92.8 | 97.7 | | Red Dead Redemption 2 | 79.1 | 83.2 | | DOOM Eternal | 57.3 | 60.3 | | Warzone | 89.4 | 94.0 | | Assassin's Creed | 96.2 | 101.3 | | Valheim | 95.1 | 100.1 |
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. So 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 compare it in one assembly with the video card that is installed in your computer.
Power consumption
| Ryzen 5 7645HX | 116% |
Ryzen 9 7845HX | 121% |
To make a finishing decision 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 9 7845HX is more energy efficient than the Ryzen 5 7645HX since it has less power consumption: 55W vs. 55W. Power consumption is especially important for laptops. Also, when choosing a processor cooling system, you must know its TDP. 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 benchmarksLet's say you plan to use the processor not only for gaming, but also for streaming, machine learning, video rendering or video editing, programming, then first of all you need to pay attention to the performance in multi-threaded mode. In this mode, to achieve maximum performance, the CPU includes all cores and threads that it has. You will learn this data from the benchmark tables below. Before using 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 run, and all the benefit of multi-core mode turns out to be unnecessary.

Comparison of specifications
In the specification comparison table, the most useful will be the the possibility of overclocking it and release date of the processor. The newer the processor, the longer it will last you. And the easier it will be to upgrade the system in the future. The same can be said about overclocking. When the processor can be overclocked, increasing its performance, then it will still be able to produce maximum FPS in the newest games. The economy are obvious! Accordingly, there is no longer a need to buy a new CPU to enjoy the games any longer.
