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 play 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 small game result, just look at the FPS that it produces in real games in the summary 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 amounts of RAM and different video cards. But users also tested them at different screen resolutions: FullHD, 2K 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 compare it in one assembly with the video card that is installed in your computer.

To make a final 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 i5-1245UL is more energy efficient than the Core i7-1255U since it has less power consumption: 15W vs. 15W. Power consumption is especially important for laptops. Also, when choosing a processor cooling system, it will be useful to 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 benchmarks

For example you want to use the processor not only for gaming, but also for programming, machine learning, streaming, video rendering or video editing, then the main parameter for you is its performance in multi-threaded mode. In this mode, to reach maximum performance, the processor turns on all cores and threads that it has. You will find out this data from the benchmark tables below. Before using the data from these tests, be sure to check whether the program you are going to use on your computer supports multi-threaded mode. Since there are still many programs that use only one core to work, and all the advantages of multi-core mode turns out to be unnecessary.

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 in your computer. 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 in the newest games. Accordingly, there is no longer a need to buy a new CPU to enjoy the games any longer. The savings are obvious!

Also keep in mind that high CPU frequency affects battery life through power consumption (relevant for laptops).

Result:
The number of parameters for which Intel Core i5-1245UL is better: 18
The number of parameters for which Intel Core i7-1255U is better: 3
Although it should be realized that all the figures in the article above do not mean that you should be guided entirely by them and trust a simple comparison of these numbers. Better to watch benchmarks video and read the opinion of of people who bought Intel Core i5-1245UL and Intel Core i7-1255U before deciding which of the processors to buy for gaming.
