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 run 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 little game result, look at the FPS that it produces in real games in the summary table below.

Valheim	135.3	106.9

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 compare it in one assembly with the 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 EPYC 7443 is more energy efficient than the EPYC 9454 as it consumes less power: 290W vs. 200W. Power consumption is particularly 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

Let's say you want to use the processor not only for gaming, but also for programming, machine learning, 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, to achieve maximum efficiency, the processor 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 find out whether the program 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 benefit of multi-core mode are unused.

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 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 in new games. It turns out that 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. Here EPYC 7443 is 3% better than EPYC 9454 in terms of CPU frequency. Another difference is that EPYC 9454 has 24 more core than EPYC 7443. 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 EPYC 9454 is better: 32
The number of parameters for which AMD EPYC 7443 is better: 3
Although it should be understood that the summary data that you have looked at here do not mean that taking them into account you should totally trust a simple comparison of these figures. Better to watch benchmarks video and read the opinion of of people who bought AMD EPYC 9454 and AMD EPYC 7443 before making a selection which processor to buy for gaming and which not.
