The maximum result in this parameter is 100 percent, which is the performance of the most powerful processor at the moment. And of course, this is a server processor, on which no one will play games. Because this processor costs several tens of thousands of dollars. Therefore, if you think that the selected CPU has a small 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 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. You will get more accurate information about how powerful 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 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 i3-10320 is more energy efficient than the Core i5-10400 since it has less power consumption: 65W vs. 65W. Power consumption is especially important for laptops. Also, when choosing a processor cooling system, you must 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

Let's say you plan to use the processor not only for gaming, but also for streaming, programming, video editing or video rendering, 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 turns on all threads and cores that it has. You will learn this data from the benchmark tables below. Before you take into account 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. Since there are still many programs that use only one core to work, and all the benefit of multi-core mode turns out to be unnecessary.

Comparison of specifications

In the specification comparison table, the processor release date and overclocking capability will be the most helpful. 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 can be said about overclocking. If the processor can be overclocked, increasing its performance, then it will continue to maintain maximum FPS in the newest games. The economy are obvious! It turns out that you do not need to buy a new CPU to enjoy the games any longer.

Part number

In this comparison block, you should pay attention to the differences in clock speed and the number of cores. Here Core i3-10320 is 23% better than Core i5-10400 in terms of CPU frequency. Another difference is that Core i5-10400 has 2 more core than Core i3-10320. 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 i3-10320 is better: 9
The number of parameters for which Intel Core i5-10400 is better: 19
However, it should be realized that all the data in the article above do not mean that taking them into account you should completely trust a simple comparison of these numbers. Better to watch the video tests and read the opinion of of people who bought Intel Core i3-10320 and Intel Core i5-10400 before deciding which of the CPUs to buy for gaming.
