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 play games. Because this processor costs several tens of thousands of dollars. And if it seems to you that the selected CPU has a low game result, 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 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: 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.

To make a final decision 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 i7-1355U is more energy efficient than the Core i7-12800H as it consumes less power: 15W vs. 45W. Power consumption is particularly important for laptops. Also, when choosing a processor cooling system, it will be useful 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

If you want to use the processor not only for gaming, but also for programming, video rendering or video editing, streaming, machine learning, then first of all you need to pay attention to the performance in multi-threaded mode. In this mode, the processor uses all threads and cores that it has to the maximum to achieve maximum efficiency. You will learn this data from the benchmark tables below. Before using 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. 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 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 can be said about overclocking. If the processor can be overclocked, increasing its performance, then it will still be able to produce maximum FPS even in the newest games. Accordingly, you do not need to buy a new CPU to enjoy the games any longer. The economy are obvious!

In this comparison block, you should pay attention to the differences in clock speed and the number of cores. Another difference is that Core i7-12800H has 4 more core than Core i7-1355U. 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 i7-1355U is better: 5
The number of parameters for which Intel Core i7-12800H is better: 26
However, it should be realized that the summary data that you have looked at here do not mean that taking them into account you should entirely trust a simple quantitative comparison. Better to watch the video tests and read the opinion of real owners of Intel Core i7-1355U and Intel Core i7-12800H before making a choice which of the processors to buy for gaming.
