The maximum result in this parameter is 100 percent, which is the performance of the most powerful processor currently available. 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 little game result, look at the FPS that it produces in real games in the final 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 amounts of RAM and different video cards. But users also tested them at different screen resolutions: 2K, FullHD or 4K. So 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 final 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 Core i5-1145G7 is more energy efficient than the Core i5-8400 as it consumes less power: 28W vs. 65W. Power consumption is especially important for laptops. Also, when choosing a processor cooling system, you need to 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

For example you plan to use the processor not only for gaming, but also for streaming, machine learning, programming, video editing or video rendering, then the main parameter for you is its performance in multi-threaded mode. In this mode, to achieve maximum efficiency, the CPU includes all cores and threads that it has. You will find out this data from the benchmark tables below. Before you take into account the data from these tests, be sure to check whether the software 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 processor release date and overclocking capability will be the most helpful. The later the processor is released, the longer it will last in your computer. And the easier it will be to upgrade the system later. The same benefits from the presence of overclocking. When the processor can be overclocked, increasing its performance, then it will still be able to produce maximum FPS even in new games. The savings are obvious! Accordingly, you do not need to buy a new CPU to enjoy the games any longer.

In this comparison block, you should pay attention to the differences in clock speed and the number of cores. Here Core i5-8400 is 7% better than Core i5-1145G7 in terms of CPU frequency. Another difference is that Core i5-8400 has 2 more core than Core i5-1145G7. 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 i5-1145G7 is better: 28
The number of parameters for which Intel Core i5-8400 is better: 6
However, it should be understood that all the data in the table above do not mean that taking them into account you should undividedly trust a simple quantitative comparison. Better to watch benchmarks video and read the opinion of of people who bought Intel Core i5-1145G7 and Intel Core i5-8400 before making a choice which CPU to buy for gaming and which not.
