For the maximum in this test, the results of the most powerful processor in the site database are taken. And it is clear that 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 low 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 tested computers not only did they have different amounts of RAM and different video cards. But users also tested them at different screen resolutions: 2K, 4K or FullHD. 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. 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 i7-6660U is more energy efficient than the Pentium Gold G7400E as it consumes less power: 15W vs. 46W. Power consumption is especially important for laptops. Also, when choosing a processor cooling system, it will be useful to know its TDP. 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 plan to use the processor not only for gaming, but also for programming, streaming, machine learning, video editing or video rendering, then the main parameter for you is its performance in multi-threaded mode. In this mode, to achieve maximum performance, the processor includes all threads and cores that it has. You will learn this data from the benchmark tables below. Before using 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 advantages of multi-core mode are unused.

Comparison of specifications

In the specification comparison table, the most useful will be the the possibility of overclocking it and release date of the processor. The later the processor is released, the longer it will last in your computer. 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, thereby increasing its performance, then it will still be able to produce maximum FPS in new games. Accordingly, you do not need to buy a new CPU to enjoy the games any longer. The savings are obvious!
