Processor comparisons 24-03-2021

   Let's say you are thinking about choosing a CPU, you will be able to make a choice by looking at the Intel Core i7-9800X vs Intel Core i5-11400 tests and see which is better for games or simple use for programming, video editing, streaming, machine learning, rendering. Here is all information from several benchmarks or real video editing and streaming tests. A careful analysis of all the technical characteristics, so that it can be easier to understand, is made by the table.
   From the video comparison, you can get the results of parallel examination in software tests such as Furmark, GeekBench 6, 5.2, Handbrake, UserBenchmark, Cinebench 23 (20, 15), PCMark 10, World of Tanks enCore Benchmark, RealBench, 3DMark, Prime95, Blender, 7zip, WPrime, MATLAB, DaVinci Resolve Studio, PassMark, VeraCrypt, SuperPi, Dolphin Emulator, Blender, AIDA64, Gears 5.
   And how good the CPUs are in games:

The maximum result in this parameter is 100 percent, which is the performance of the most powerful processor currently available. And it is clear that this is a server processor, on which no one will run games. Because this processor costs 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: 2K, FullHD or 4K. So 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 compare it in one assembly with the video card that is installed in your computer.

To make a final 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 i5-11400 is more energy efficient than the Core i7-9800X since it has less power consumption: 165W vs. 65W. Power consumption is especially important for laptops. And TDP should be taken into account when choosing a processor cooling system. 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 want to use the processor not only for gaming, but also for machine learning, streaming, programming, video rendering or video editing, then first of all you need to pay attention to the 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 using 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 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 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 you. And the easier it will be to upgrade the system in the future. The same can be said about overclocking. When the processor can be overclocked, thereby increasing its performance, then it will continue to maintain maximum FPS even in the newest games. The economy 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 i7-9800X is 31% better than Core i5-11400 in terms of CPU frequency. Another difference is that Core i7-9800X has 2 more core than Core i5-11400. 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 i7-9800X is better: 21
The number of parameters for which Intel Core i5-11400 is better: 11
Although it should be understood that the summary data that you have looked at here do not mean that taking them into account you should totally trust a simple comparison of these figures. Better to watch benchmarks video and read the opinion of of people who bought Intel Core i7-9800X and Intel Core i5-11400 before making a selection which processor to buy for gaming and which not.
