Intel Core i3-8100 vs Intel Core i7-7700

Processor comparisons 04-02-2023

   For example you can't decide which CPU to buy, you can make a decision by looking at the Intel Core i3-8100 vs Intel Core i7-7700 tests and decide which is better for games or simple use for video editing, programming, machine learning, streaming, rendering. Here is useful information from real video editing and streaming tests or many benchmarks. A step-by-step 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 software tests like WPrime, GeekBench 6, 5.2, Prime95, 3DMark, 7zip, UserBenchmark, AIDA64, Furmark, DaVinci Resolve Studio, VeraCrypt, World of Tanks enCore Benchmark, Blender, PCMark 10, Blender, Cinebench 23 (20, 15), Handbrake, Gears 5, Dolphin Emulator, MATLAB, RealBench, SuperPi, PassMark.

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 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 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: 2K, FullHD or 4K. Therefore, 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 final 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 i7-7700 is more energy efficient than the Core i3-8100 since it has less power consumption: 65W vs. 65W. Power consumption is especially important for laptops. Also, when choosing a processor cooling system, you need to know its TDP. It is necessary to calculate so that the TDP data specified in the cooler specification is greater than the TDP of the compared processor.

Software benchmarks

If you want to use the processor not only for gaming, but also for video editing or video rendering, machine learning, streaming, programming, then the main parameter for you is its performance in multi-threaded mode. In this mode, the CPU includes 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 make sure that the software that you are going to use on your computer can work in multi-threaded mode. Since there are still many programs that use only one core to run, and all the benefit of multi-core mode turns out to be unnecessary.

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 in your computer. And the easier it will be to upgrade the system later. The same benefits from the presence of overclocking. When the processor can be overclocked, increasing its performance, then it will continue to maintain maximum FPS in the newest games. The economy are obvious! It turns out that 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. 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 i3-8100 is better: 4
The number of parameters for which Intel Core i7-7700 is better: 25
Although it should be realized that all the data in the article above do not mean that you should be guided entirely by them and trust a simple quantitative comparison. Better to watch benchmarks video and read the reviews of real owners of Intel Core i3-8100 and Intel Core i7-7700 before deciding which of the CPUs to buy for gaming.
