The maximum result in this parameter is 100 percent, which is the performance of the most powerful processor at the moment. 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. Therefore, if you think that the selected CPU has a low game result, just look at the FPS that it produces in real games in the final table below.
List of other games in which processors were compared: Monster Hunter World, Ghostrunner, Hitman 3, Forza Horizon 4, Half-Life: Alyx, Shadow of the Tomb Raider, The Witcher 3: Wild Hunt, League of Legends (LOL), Battlefield V, Resident Evil 7 Biohazard, PlayerUnknown's Battlegrounds (PUBG), DOTA 2A, Counter-Strike: Global Offensive (CS GO), Horizon Zero Dawn, Microsoft Flight Simulator, Metro Exodus, Control, NBA 2K20.

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. 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
Core i7-1255U278% Core i9-9900KS35%
To make a finishing decision 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 i9-9900KS as it consumes less power: 15W vs. 127W. Power consumption is especially important for laptops. Also, when choosing a processor cooling system, you must know its TDP. It is necessary to calculate so that the TDP data specified in the cooler specification is greater than the TDP of the compared processor.

Software benchmarks

If you want to use the processor not only for gaming, but also for video rendering or video editing, programming, machine learning, streaming, then first of all you need to pay attention to the performance in multi-threaded mode. In this mode, the processor includes all threads and cores that it has to the maximum to reach 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 find out whether 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 most helpful will be the release date of the processor and the possibility of overclocking it. 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 continue to maintain maximum FPS 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 savings are obvious!
