Processor comparisons 12-06-2021

   If you can't decide which processor to buy, you can make a decision by looking at the Intel Core i9-11900H vs Intel Core i9-7940X tests and decide which is better for games or normal use for video editing, machine learning, programming, streaming, rendering. Here is useful information from real streaming and video editing tests or several benchmarks. A thorough review of all the specifications, to make it easier to understand, is summarized in the table.
   From the video comparison, you can get the results of parallel examination in synthetic type tests like Prime95, Cinebench 23 (20, 15), UserBenchmark, GeekBench 6, 5.2, DaVinci Resolve Studio, SuperPi, Gears 5, WPrime, Blender, Furmark, RealBench, World of Tanks enCore Benchmark, VeraCrypt, Blender, 7zip, Handbrake, PassMark, Dolphin Emulator, 3DMark, PCMark 10, AIDA64, MATLAB.
   And how good the processors 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 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 low 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 tested computers not only did they have different video cards and different amounts of RAM. But users also tested them at different screen resolutions: FullHD, 2K 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. 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 i9-11900H is more energy efficient than the Core i9-7940X since it has less power consumption: 125W vs. 165W. 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

For example you want to use the processor not only for gaming, but also for video rendering or video editing, streaming, programming, machine learning, then the main parameter for you is its performance in multi-threaded mode. In this mode, the CPU uses all threads and cores that it has to the maximum to achieve maximum efficiency. 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 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 benefit of multi-core mode are unused.

Comparison of specifications

In the specification comparison table, the most helpful will be the the possibility of overclocking it and release date of the processor. 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 still be able to produce maximum FPS even in the newest games. The savings are obvious! It turns out that you do not need to buy a new CPU to enjoy the games any longer.
