Summary benchmark resultsAs a percentage of the maximum value based on a sample from the entire base of all processors
Processor Benchmark
| Ryzen 5 7645HX | 61% |
Ryzen 7 7745HX | 63% |
This value shows the performance of the processors in single-threaded and multi-threaded mode. In this comparison, Ryzen 7 7745HX is 3% better than Ryzen 5 7645HX. The data source is several popular tests. More detailed information of the benchmarks is below.
Gaming performance
Summary result of all game benchmarks.| Ryzen 5 7645HX | 57% |
Ryzen 7 7745HX | 60% |
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 less popular games in which CPU comparisons were performed: Shadow of the Tomb Raider, NBA 2K20, The Witcher 3: Wild Hunt, Monster Hunter World, Hitman 3, Half-Life: Alyx, Forza Horizon 4, Metro Exodus, Control, DOTA 2A, Counter-Strike: Global Offensive (CS GO), Battlefield V, PlayerUnknown's Battlegrounds (PUBG), Horizon Zero Dawn, Microsoft Flight Simulator, League of Legends (LOL), Ghostrunner, Resident Evil 7 Biohazard.
Gaming benchmark| Fortnite | 100.8 | 105.9 | | Valorant | 114.6 | 120.4 | | Cyberpunk 2077 | 64.2 | 67.4 | | Apex Legends | 107.7 | 113.2 | | Call of Duty Warzone | 85.9 | 90.3 | | Overwatch | 92.8 | 97.5 | | Red Dead Redemption 2 | 79.1 | 83.1 | | DOOM Eternal | 57.3 | 60.2 | | Warzone | 89.4 | 93.9 | | Assassin's Creed | 96.2 | 101.1 | | Valheim | 95.1 | 99.9 |
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 comparisons not only were the equipped with 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. To be sure exactly how much performance 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 7 7745HX | 114% |
To make a finishing choice 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 7645HX is more energy efficient than the Ryzen 7 7745HX as it consumes less power: 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 calculate so that the TDP data specified in the cooler specification is greater than the TDP of the compared processor.
Software benchmarksIf you want to use the processor not only for gaming, but also for machine learning, programming, video rendering or video editing, streaming, then first of all you need to pay attention to the performance in multi-threaded mode. In this mode, the CPU includes all threads and cores that it has to the maximum to reach maximum performance. 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 work, and all the advantages of multi-core mode turns out to be unnecessary.

Comparison of specifications
In the specification comparison table, the most helpful will be the the possibility of overclocking it and release date of the processor. 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, thereby increasing its performance, then it will still be able to produce maximum FPS in the newest games. Accordingly, there is no longer a need to buy a new CPU to enjoy the games any longer. The savings are obvious!
