Processor comparisons 18-03-2021

   For example you can't decide which processor to buy, you can make a decision by looking at the AMD Ryzen 7 3800XT vs Intel Core i9-11900K tests and decide which is better for games or normal use for streaming, video editing, rendering, machine learning, programming. Here is useful information from several benchmarks or real video editing and streaming tests. A step-by-step analysis of all the specifications, so that it can be easier to understand, is presented in the form of the table.
   From the video comparison, you can get the results of parallel examination in special test applications such as Blender, 7zip, AIDA64, Blender, VeraCrypt, Gears 5, PassMark, WPrime, UserBenchmark, Furmark, Cinebench 23 (20, 15), Dolphin Emulator, PCMark 10, DaVinci Resolve Studio, GeekBench 6, 5.2, MATLAB, RealBench, 3DMark, SuperPi, Handbrake, Prime95, 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 of course, 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. And if it seems to you that the selected CPU has a little game result, 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 that were in the comparisons not only did they have 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. 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. The newer the processor generation, the better its performance in games and benchmarks, as well as its energy efficiency. In this case the Core i9-11900K is more energy efficient than the Ryzen 7 3800XT as it consumes less power: 105W vs. 125W. 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

Let's say you want to use the processor not only for gaming, but also for streaming, machine learning, programming, video editing or video rendering, then first of all you need to pay attention to the performance in multi-threaded mode. In this mode, the CPU includes all cores and threads 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 find out whether the program that you are going to use on your computer can work in multi-threaded mode. Because there are still many programs that can use only one core to run, and all the advantages of multi-core mode are unused.

Comparison of specifications

In the specification comparison table, the processor release date and overclocking capability will be the most helpful. The newer the processor, the longer it will last you. And the easier it will be to upgrade the system later. 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 even in new 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!
