Processor comparisons 18-01-2022

   Let's say there are difficulties with the choice of a processor, you will solve them by reading the full tests Intel Core i5-9600T vs Intel Core i5-8400 and decide which is better for games or simple use for video editing, machine learning, programming, streaming, rendering. Here is all information from several benchmarks or real streaming and video editing tests. A careful analysis of all the technical characteristics, so that it can be easier to understand, is summarized in the table.
   From the comparison video, you can get the results of parallel examination in special test applications like 7zip, Furmark, Dolphin Emulator, RealBench, GeekBench 6, 5.2, WPrime, Cinebench 23 (20, 15), AIDA64, VeraCrypt, Blender, Handbrake, PassMark, SuperPi, DaVinci Resolve Studio, Prime95, MATLAB, 3DMark, Gears 5, Blender, PCMark 10, UserBenchmark, World of Tanks enCore Benchmark.

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 the cost of this processor reaches several tens of thousands of dollars. And if it seems to you 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: 4K, 2K or FullHD. 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 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 i5-9600T is more energy efficient than the Core i5-8400 as it consumes less power: 35W vs. 65W. Power consumption is particularly 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

If you plan to use the processor not only for gaming, but also for programming, streaming, machine learning, video rendering or video editing, then the main parameter for you is its performance in multi-threaded mode. In this mode, the processor turns on all threads and cores that it has to the maximum to achieve maximum performance. You will learn this data from the benchmark tables below. Before you take into account the data from these tests, be sure to check whether the program you are going to use on your computer supports multi-threaded mode. Because there are still many programs that use only one core to work, and all the benefit of multi-core mode are unused.

Comparison of specifications

In the specification comparison table, the most helpful 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 in the future. The same benefits from the presence of overclocking. When the processor can be overclocked, thereby increasing its performance, then it will continue to maintain 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!
