Ryzen 9 4900HS | 54% |
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 this processor costs 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 final table below.
List of less popular games in which CPU comparisons were performed: DOTA 2A, Battlefield V, Half-Life: Alyx, Metro Exodus, PlayerUnknown's Battlegrounds (PUBG), League of Legends (LOL), Control, Monster Hunter World, Ghostrunner, Horizon Zero Dawn, The Witcher 3: Wild Hunt, Microsoft Flight Simulator, NBA 2K20, Hitman 3, Shadow of the Tomb Raider, Counter-Strike: Global Offensive (CS GO), Forza Horizon 4, Resident Evil 7 Biohazard.
Gaming benchmark| Fortnite | 100.8 | 96.2 | | Valorant | 114.6 | 109.3 | | Cyberpunk 2077 | 64.2 | 61.2 | | Apex Legends | 107.7 | 102.8 | | Call of Duty Warzone | 85.9 | 82.0 | | Overwatch | 92.8 | 88.5 | | Red Dead Redemption 2 | 79.1 | 75.4 | | DOOM Eternal | 57.3 | 54.7 | | Warzone | 89.4 | 85.3 | | Assassin's Creed | 96.2 | 91.8 | | Valheim | 95.1 | 90.7 |
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: 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 5 7645HX | 116% |
Ryzen 9 4900HS | 118% |
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 9 4900HS is more energy efficient than the Ryzen 5 7645HX since it has less power consumption: 55W vs. 35W. 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 video editing or video rendering, machine learning, streaming, programming, then the main parameter for you is its performance in multi-threaded mode. In this mode, the CPU includes all threads and cores that it has to the maximum to achieve maximum efficiency. You will learn this data from the benchmark tables below. Before you take into account the data from these tests, be sure to make sure that the software that you are going to use on your computer can work in multi-threaded mode. Since there are still many programs that use only one core to run, and all the benefit of multi-core mode turns out to be unnecessary.

Comparison of specifications
In the specification comparison table, the processor release date and overclocking capability will be the most useful. 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. When the processor can be overclocked, increasing its performance, then it will still be able to produce maximum FPS even in the newest games. It turns out that there is no longer a need to buy a new CPU to enjoy the games any longer. The economy are obvious!
