Gaming performance
Summary result of all game benchmarks.| Core i5-1245U | 53% |
Core i7-1255U | 54% |
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 run games. Because the cost of this processor reaches several tens of thousands of dollars. And if it seems to you that the selected CPU has a little game result, look at the FPS that it produces in real games in the summary table below.
List of other games in which processors were compared: The Witcher 3: Wild Hunt, Half-Life: Alyx, Microsoft Flight Simulator, Forza Horizon 4, NBA 2K20, Horizon Zero Dawn, Battlefield V, Ghostrunner, Monster Hunter World, Metro Exodus, PlayerUnknown's Battlegrounds (PUBG), Hitman 3, Counter-Strike: Global Offensive (CS GO), Control, Shadow of the Tomb Raider, Resident Evil 7 Biohazard, League of Legends (LOL), DOTA 2A.
Gaming benchmark| Fortnite | 94.9 | 95.1 | | Valorant | 107.9 | 108.1 | | Cyberpunk 2077 | 60.4 | 60.5 | | Apex Legends | 101.4 | 101.6 | | Call of Duty Warzone | 80.9 | 81.0 | | Overwatch | 87.4 | 87.5 | | Red Dead Redemption 2 | 74.4 | 74.6 | | DOOM Eternal | 53.9 | 54.0 | | Warzone | 84.2 | 84.3 | | Assassin's Creed | 90.6 | 90.8 | | Valheim | 89.5 | 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 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. 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
| Core i5-1245U | 272% |
Core i7-1255U | 278% |
To make a final choice 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 Core i7-1255U is more energy efficient than the Core i5-1245U as it consumes less power: 15W vs. 15W. Power consumption is particularly important for laptops. Also, when choosing a processor cooling system, you must know its TDP. 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 benchmarksFor example you want to use the processor not only for gaming, but also for machine learning, video rendering or video editing, programming, streaming, then first of all you need to pay attention to the performance in multi-threaded mode. In this mode, the CPU uses all cores and threads that it has to the maximum to reach maximum performance. You will find out this data from the benchmark tables below. Before you take into account the data from these tests, be sure to find out whether the software that you are going to use on your computer can work in multi-threaded mode. Because 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 release date of the processor and the possibility of overclocking it. The later the processor is released, 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. If the processor can be overclocked, increasing its performance, then it will continue to maintain maximum FPS even in new games. The savings are obvious! It turns out that you do not need to buy a new CPU to enjoy the games any longer.
