Summary benchmark resultsAs a percentage of the maximum value based on a sample from the entire base of all processors
Processor Benchmark
| Ryzen 7 7840HS | 59% |
Ryzen 5 7645HX | 61% |
This shows the performance of the processors in single-threaded and multi-threaded mode. In this comparison, Ryzen 5 7645HX is 3% better than Ryzen 7 7840HS. The data source is several popular tests. More detailed information of the benchmarks is below.
Gaming performance
Summary result of all game benchmarks.| Ryzen 7 7840HS | 57% |
Ryzen 5 7645HX | 57% |
The maximum result in this parameter is 100 percent, which is the performance of the most powerful processor at the moment. And it is clear that 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 final table below.
List of other games in which CPU comparisons were performed: Shadow of the Tomb Raider, DOTA 2A, Control, Forza Horizon 4, Metro Exodus, Battlefield V, Horizon Zero Dawn, Resident Evil 7 Biohazard, PlayerUnknown's Battlegrounds (PUBG), NBA 2K20, Hitman 3, The Witcher 3: Wild Hunt, Microsoft Flight Simulator, Counter-Strike: Global Offensive (CS GO), Ghostrunner, Monster Hunter World, League of Legends (LOL), Half-Life: Alyx.
Gaming benchmark| Fortnite | 100.5 | 100.8 | | Valorant | 114.2 | 114.6 | | Cyberpunk 2077 | 64.0 | 64.2 | | Apex Legends | 107.4 | 107.7 | | Call of Duty Warzone | 85.7 | 85.9 | | Overwatch | 92.5 | 92.8 | | Red Dead Redemption 2 | 78.8 | 79.1 | | DOOM Eternal | 57.1 | 57.3 | | Warzone | 89.1 | 89.4 | | Assassin's Creed | 96.0 | 96.2 | | Valheim | 94.8 | 95.1 |
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 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. 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 7 7840HS | 156% |
Ryzen 5 7645HX | 116% |
To make a final 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 7 7840HS is more energy efficient than the Ryzen 5 7645HX as it consumes less power: 40W vs. 55W. Power consumption is particularly important for laptops. Also, when choosing a processor cooling system, it will be useful to 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 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 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 in the newest games. The economy are obvious! It turns out that you do not need to buy a new CPU to enjoy the games any longer.
