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 this processor costs several tens of thousands of dollars. Therefore, if you think that the selected CPU has a little game result, just look at the FPS that it produces in real games in the final table below.

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 tested computers not only did they have different video cards and different amounts of RAM. But users also tested them at different screen resolutions: 2K, FullHD or 4K. So 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.

To make a final resolution 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 9 7940HS as it consumes less power: 40W vs. 15W. Power consumption is especially important for laptops. Also, when choosing a processor cooling system, you need 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 benchmarks

For example you plan to use the processor not only for gaming, but also for streaming, programming, video editing or video rendering, machine learning, then the main parameter for you is its performance in multi-threaded mode. In this mode, the CPU turns on 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 using the data from these tests, be sure to check whether the software you are going to use on your computer supports 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 later the processor is released, the longer it will last you. And the easier it will be to upgrade the system later. The same can be said about overclocking. If the processor can be overclocked, increasing its performance, then it will still be able to produce maximum FPS in new games. It turns out that you do not need to buy a new CPU to enjoy the games any longer. The economy are obvious!
