For the maximum in this test, the results of the most powerful processor in the site database are taken. And of course, this is a server processor, on which no one will run games. Because the cost of this processor reaches 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 less popular games in which processors were compared: Horizon Zero Dawn, Counter-Strike: Global Offensive (CS GO), Hitman 3, Forza Horizon 4, The Witcher 3: Wild Hunt, Resident Evil 7 Biohazard, Control, PlayerUnknown's Battlegrounds (PUBG), Monster Hunter World, Ghostrunner, Metro Exodus, League of Legends (LOL), Battlefield V, Half-Life: Alyx, Microsoft Flight Simulator, NBA 2K20, Shadow of the Tomb Raider, DOTA 2A.
Gaming benchmark| Fortnite | 100.5 | 108.7 | | Valorant | 114.2 | 123.5 | | Cyberpunk 2077 | 64.0 | 69.2 | | Apex Legends | 107.4 | 116.1 | | Call of Duty Warzone | 85.7 | 92.7 | | Overwatch | 92.5 | 100.1 | | Red Dead Redemption 2 | 78.8 | 85.2 | | DOOM Eternal | 57.1 | 61.8 | | Warzone | 89.1 | 96.4 | | Assassin's Creed | 96.0 | 103.8 | | Valheim | 94.8 | 102.5 |
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, 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 compare it in one assembly with the video card that is installed in your computer.
Power consumption
| Ryzen 7 7840HS | 156% |
Ryzen 9 7945HX | 127% |
To make a finishing choice 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 Ryzen 7 7840HS is more energy efficient than the Ryzen 9 7945HX since it has less power consumption: 40W vs. 55W. Power consumption is particularly 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 programming, video editing or video rendering, streaming, machine learning, then first of all you need to pay attention to the performance in multi-threaded mode. In this mode, to reach maximum performance, the CPU turns on 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 check whether the software you are going to use on your computer supports multi-threaded mode. Because there are still many programs that 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 most useful will be the the possibility of overclocking it and release date of the processor. The later the processor is released, the longer it will last in your computer. And the easier it will be to upgrade the system in the future. The same can be said about overclocking. If the processor can be overclocked, thereby increasing its performance, then it will still be able to produce maximum FPS in new games. Accordingly, you do not need to buy a new CPU to enjoy the games any longer. The savings are obvious!
