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 run games. Because the cost of this processor reaches 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 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 comparing not only were the equipped with different video cards and different amounts of RAM. But users also tested them at different screen resolutions: FullHD, 2K 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 get acquainted with the benchmarks that are made with the same 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. 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 Core i3-1115GRE is more energy efficient than the Core i5-7400 as it consumes less power: 15W 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 calculate so that the TDP data specified in the cooler specification is greater than the TDP of the compared processor.

Software benchmarks

For example you want to use the processor not only for gaming, but also for programming, streaming, video rendering or video editing, machine learning, then the main parameter for you is its performance in multi-threaded mode. In this mode, to achieve maximum efficiency, the processor uses all threads and cores 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. Since there are still many programs that use only one core to run, and all the benefit of multi-core mode turns out to be unnecessary.

Comparison of specifications

In the specification comparison table, the most useful 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 in your computer. And the easier it will be to upgrade the system later. The same can be said about overclocking. If the processor can be overclocked, thereby increasing its performance, then it will continue to maintain maximum FPS even 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!
