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: 2K, FullHD or 4K. Therefore, 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.

To make a finishing 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 Ryzen 5 7645HX is more energy efficient than the Ryzen 7 4800H as it consumes less power: 55W vs. 45W. Power consumption is particularly important for laptops. And TDP should be taken into account when choosing a processor cooling system. 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, video editing or video rendering, programming, machine learning, then first of all you need to pay attention to the performance in multi-threaded mode. In this mode, to achieve maximum performance, the processor uses all threads and cores 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. Because there are still many programs that can use only one core to work, 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 newer the processor, the longer it will last you. 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, thereby increasing its performance, then it will continue to maintain maximum FPS in the newest games. It turns out that there is no longer a need to buy a new CPU to enjoy the games any longer. The savings are obvious!

In this comparison block, you should pay attention to the differences in clock speed and the number of cores. Here Ryzen 5 7645HX is 27% better than Ryzen 7 4800H in terms of CPU frequency. Another difference is that Ryzen 7 4800H has 2 more core than Ryzen 5 7645HX. Also keep in mind that high CPU frequency affects battery life through power consumption (relevant for laptops).

Result:
The number of parameters for which AMD Ryzen 5 7645HX is better: 31
The number of parameters for which AMD Ryzen 7 4800H is better: 4
However, it should be understood that the summary data that you have looked at here do not mean that taking them into account you should undividedly trust a simple comparison of these numbers. Better to watch the video tests and read the reviews of of people who bought AMD Ryzen 5 7645HX and AMD Ryzen 7 4800H before making a choice which processor to buy for gaming and which not.
