Summary benchmark resultsAs a percentage of the maximum value based on a sample from the entire base of all processors
Processor Benchmark
| Ryzen 7 7745HX | 63% |
Ryzen 9 7945HX | 65% |
This value shows the performance of the processors in single-threaded and multi-threaded mode. In this comparison, Ryzen 9 7945HX is 3% better than Ryzen 7 7745HX. The data source is several popular tests. Detailed information can be found below.
Gaming performance
Summary result of all game benchmarks.| Ryzen 7 7745HX | 60% |
Ryzen 9 7945HX | 61% |
The maximum result in this parameter is 100 percent, which is the performance of the most powerful processor at the moment. 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 small game result, just look at the FPS that it produces in real games in the summary table below.
List of other games in which processors were compared: PlayerUnknown's Battlegrounds (PUBG), Half-Life: Alyx, Monster Hunter World, Ghostrunner, NBA 2K20, League of Legends (LOL), Forza Horizon 4, DOTA 2A, Resident Evil 7 Biohazard, Battlefield V, Microsoft Flight Simulator, The Witcher 3: Wild Hunt, Hitman 3, Metro Exodus, Shadow of the Tomb Raider, Control, Counter-Strike: Global Offensive (CS GO), Horizon Zero Dawn.
Gaming benchmark| Fortnite | 105.9 | 108.7 | | Valorant | 120.4 | 123.5 | | Cyberpunk 2077 | 67.4 | 69.2 | | Apex Legends | 113.2 | 116.1 | | Call of Duty Warzone | 90.3 | 92.7 | | Overwatch | 97.5 | 100.1 | | Red Dead Redemption 2 | 83.1 | 85.2 | | DOOM Eternal | 60.2 | 61.8 | | Warzone | 93.9 | 96.4 | | Assassin's Creed | 101.1 | 103.8 | | Valheim | 99.9 | 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: 4K, 2K 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
| Ryzen 7 7745HX | 114% |
Ryzen 9 7945HX | 127% |
To make a finishing resolution 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 7945HX is more energy efficient than the Ryzen 7 7745HX as it consumes less power: 55W vs. 55W. Power consumption is particularly important for laptops. And TDP should be taken into account when choosing a processor cooling system. 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, streaming, machine learning, video editing or video rendering, then first of all you need to pay attention to the performance in multi-threaded mode. In this mode, the CPU turns on all threads and cores that it has to the maximum to achieve maximum efficiency. You will find out 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 can use only one core to work, and all the benefit 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 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 benefits from the presence of overclocking. When the processor can be overclocked, thereby increasing its performance, then it will continue to maintain 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!
