Gaming performance
Summary result of all game benchmarks.| Ryzen 5 7645HX | 57% |
Core i7-1255U | 54% |
For the maximum in this test, the results of the most powerful processor in the site database are taken. And it is clear that this is a server processor, on which no one will play games. Because this processor costs several tens of thousands of dollars. And if it seems to you that the selected CPU has a little game result, just look at the FPS that it produces in real games in the summary table below.
List of less popular games in which processors were compared: Battlefield V, Monster Hunter World, Horizon Zero Dawn, Shadow of the Tomb Raider, Ghostrunner, NBA 2K20, The Witcher 3: Wild Hunt, Microsoft Flight Simulator, DOTA 2A, Forza Horizon 4, Half-Life: Alyx, Resident Evil 7 Biohazard, Metro Exodus, League of Legends (LOL), Control, Hitman 3, PlayerUnknown's Battlegrounds (PUBG), Counter-Strike: Global Offensive (CS GO).
Gaming benchmark| Fortnite | 100.8 | 95.1 | | Valorant | 114.6 | 108.1 | | Cyberpunk 2077 | 64.2 | 60.5 | | Apex Legends | 107.7 | 101.6 | | Call of Duty Warzone | 85.9 | 81.0 | | Overwatch | 92.8 | 87.5 | | Red Dead Redemption 2 | 79.1 | 74.6 | | DOOM Eternal | 57.3 | 54.0 | | Warzone | 89.4 | 84.3 | | Assassin's Creed | 96.2 | 90.8 | | Valheim | 95.1 | 89.7 |
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: 2K, FullHD or 4K. 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 compare it in one assembly with the video card that is installed in your computer.
Power consumption
| Ryzen 5 7645HX | 116% |
Core i7-1255U | 278% |
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 Core i7-1255U is more energy efficient than the Ryzen 5 7645HX as it consumes less power: 55W vs. 15W. Power consumption is particularly 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 benchmarksLet's say you want to use the processor not only for gaming, but also for programming, streaming, machine learning, video editing or video rendering, then the main parameter for you is its performance in multi-threaded mode. In this mode, to reach maximum efficiency, the CPU turns on all threads and cores that it has. You will learn this data from the benchmark tables below. Before you take into account the data from these tests, be sure to check whether the software you are going to use on your computer supports multi-threaded mode. Since there are still many programs that use only one core to run, and all the advantages 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 you. 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, increasing its performance, then it will continue to maintain maximum FPS even in the newest games. The savings are obvious! Accordingly, you do not need to buy a new CPU to enjoy the games any longer.
