Intel Core i5-8400H vs Intel Core i5-10400H

Processor comparisons   20-01-2022
   For example you can't decide which CPU to buy, you can make a choice after reading the comprehensive tests Intel Core i5-8400H vs Intel Core i5-10400H and decide which is better for games or normal use for machine learning, programming, streaming, rendering, video editing. Here is useful information from many benchmarks or real video editing and streaming tests. A thorough analysis of all the technical characteristics, to make it easier to understand, is summarized in the table.
   From the comparison video, you can get the results of parallel examination in synthetic type tests like GeekBench 6, 5.2, UserBenchmark, 3DMark, DaVinci Resolve Studio, VeraCrypt, PassMark, PCMark 10, Gears 5, Dolphin Emulator, World of Tanks enCore Benchmark, SuperPi, Blender, 7zip, RealBench, Furmark, AIDA64, Handbrake, Prime95, WPrime, Cinebench 23 (20, 15), MATLAB, Blender.
   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 at the moment. 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 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: 4K, 2K or FullHD. 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 compare it in one assembly with the 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 i5-8400H is more energy efficient than the Core i5-10400H since it has less power consumption: 45W vs. 45W. 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

For example you want to use the processor not only for gaming, but also for video editing or video rendering, programming, machine learning, streaming, then first of all you need to pay attention to the performance in multi-threaded mode. In this mode, the CPU includes all threads and cores that it has to the maximum to reach maximum efficiency. 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 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 helpful will be the release date of the processor and the possibility of overclocking it. The newer the processor, the longer it will last you. 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 the newest games. It turns out that there is no longer a need to buy a new CPU to enjoy the games any longer. The savings are obvious!

In this comparison block, you should pay attention to the differences in clock speed and the number of cores. Here Core i5-10400H is 3% better than Core i5-8400H in terms of CPU frequency. 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 i5-8400H is better: 1
The number of parameters for which Intel Core i5-10400H is better: 27
Although it should be understood that all the data in the table above do not mean that taking them into account you should completely trust a simple quantitative comparison. Be sure to watch the video tests and read the opinion of real owners of Intel Core i5-8400H and Intel Core i5-10400H before making a selection which processor to buy for gaming and which not.
