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 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 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 that were in the comparisons not only did they have different video cards and different amounts of RAM. But users also tested them at different screen resolutions: 4K, 2K or FullHD. So the game benchmark data is approximate. But all video cards met the average system requirements of games. To be sure exactly how much performance 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

Ryzen 7 5800U

244%

To make a finishing resolution 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 Ryzen 7 5800U is more energy efficient than the Ryzen 7 7840HS since it has less power consumption: 40W vs. 20W. Power consumption is especially important for laptops. And TDP should be taken into account when choosing a processor cooling system. 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 plan 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 achieve maximum performance, the CPU includes 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 make sure that the software that you are going to use on your computer can work in multi-threaded mode. Because there are still many programs that can use only one core to run, and all the advantages of multi-core mode turns out to be unnecessary.

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!
