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 9 7945HX | 65% |
The number of this parameter shows the performance of the processors in single-threaded and multi-threaded mode. In this comparison, Ryzen 9 7945HX is 6% 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 9 7945HX | 61% |
The maximum result in this parameter is 100 percent, which is the performance of the most powerful processor currently available. And it is clear that this is a server processor, on which no one will play 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, 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: Battlefield V, The Witcher 3: Wild Hunt, Half-Life: Alyx, Forza Horizon 4, NBA 2K20, PlayerUnknown's Battlegrounds (PUBG), Counter-Strike: Global Offensive (CS GO), Horizon Zero Dawn, DOTA 2A, Metro Exodus, Shadow of the Tomb Raider, League of Legends (LOL), Microsoft Flight Simulator, Control, Ghostrunner, Resident Evil 7 Biohazard, Hitman 3, Monster Hunter World.
Gaming benchmark| Fortnite | 100.8 | 108.7 | | Valorant | 114.6 | 123.5 | | Cyberpunk 2077 | 64.2 | 69.2 | | Apex Legends | 107.7 | 116.1 | | Call of Duty Warzone | 85.9 | 92.7 | | Overwatch | 92.8 | 100.1 | | Red Dead Redemption 2 | 79.1 | 85.2 | | DOOM Eternal | 57.3 | 61.8 | | Warzone | 89.4 | 96.4 | | Assassin's Creed | 96.2 | 103.8 | | Valheim | 95.1 | 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 tested computers not only did they have different amounts of RAM and different video cards. But users also tested them at different screen resolutions: 2K, FullHD or 4K. So 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 9 7945HX | 127% |
To make a finishing resolution 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 9 7945HX 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. And TDP should be taken into account when choosing a processor cooling system. You need to buy a cooler that has the TDP data specified in the specification was greater than the TDP of the compared processor.
Software benchmarksIf you want to use the processor not only for gaming, but also for streaming, programming, 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, to achieve maximum performance, the CPU uses 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 work, and all the advantages of multi-core mode are unused.

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 you. 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 still be able to produce maximum FPS even in the newest games. The savings are obvious! It turns out that you do not need to buy a new CPU to enjoy the games any longer.
