The number of this parameter shows the performance of the processors in single-threaded and multi-threaded mode. In this comparison, Ryzen 5 7645HX is 11% better than Ryzen 7 4700U. The data source is several popular tests. Detailed information can be found below.
Gaming performance
Summary result of all game benchmarks.| Ryzen 5 7645HX | 57% |
Ryzen 7 4700U | 53% |
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 play games. Because this processor costs several tens of thousands of dollars. Therefore, if you think that the selected CPU has a small game result, look at the FPS that it produces in real games in the summary table below.
List of other games in which CPU comparisons were performed: Ghostrunner, Counter-Strike: Global Offensive (CS GO), Half-Life: Alyx, Hitman 3, Monster Hunter World, NBA 2K20, Resident Evil 7 Biohazard, League of Legends (LOL), Microsoft Flight Simulator, Shadow of the Tomb Raider, DOTA 2A, Horizon Zero Dawn, The Witcher 3: Wild Hunt, Forza Horizon 4, PlayerUnknown's Battlegrounds (PUBG), Battlefield V, Control, Metro Exodus.
Gaming benchmark| Fortnite | 100.8 | 94.4 | | Valorant | 114.6 | 107.3 | | Cyberpunk 2077 | 64.2 | 60.1 | | Apex Legends | 107.7 | 100.8 | | Call of Duty Warzone | 85.9 | 80.5 | | Overwatch | 92.8 | 86.9 | | Red Dead Redemption 2 | 79.1 | 74.0 | | DOOM Eternal | 57.3 | 53.6 | | Warzone | 89.4 | 83.7 | | Assassin's Creed | 96.2 | 90.1 | | Valheim | 95.1 | 89.0 |
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 amounts of RAM and different video cards. But users also tested them at different screen resolutions: 2K, FullHD or 4K. 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 4700U | 268% |
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 7 4700U is more energy efficient than the Ryzen 5 7645HX as it consumes less power: 55W vs. 15W. 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 programming, video rendering or video editing, machine learning, streaming, then first of all you need to pay attention to the performance in multi-threaded mode. In this mode, to achieve maximum efficiency, the processor uses all threads and cores that it has. You will find out this data from the benchmark tables below. Before you take into account 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. Because there are still many programs that use only one core to run, and all the benefit of multi-core mode are unused.

Comparison of specifications
In the specification comparison table, the processor release date and overclocking capability will be the most helpful. 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 can be said about overclocking. If the processor can be overclocked, thereby increasing its performance, then it will continue to maintain maximum FPS even in the newest games. The economy are obvious! Accordingly, there is no longer a need to buy a new CPU to enjoy the games any longer.
