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 finishing choice 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 Ryzen 7 7840HS is more energy efficient than the Core i9-12900H as it consumes less power: 40W vs. 45W. 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

For example you plan to use the processor not only for gaming, but also for machine learning, programming, streaming, video rendering or video editing, then first of all you need to pay attention to the 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 you take into account the data from these tests, be sure to make sure that the program 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 benefit of multi-core mode turns out to be unnecessary.

Comparison of specifications

In the specification comparison table, the most useful will be the the possibility of overclocking it and release date of the processor. The later the processor is released, the longer it will last in your computer. 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, increasing its performance, then it will continue to maintain maximum FPS in the newest games. The savings are obvious! It turns out that there is no longer a need to buy a new CPU to enjoy the games any longer.
