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 play games. Because the cost of this processor reaches several tens of thousands of dollars. Therefore, if you think 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.
List of other games in which CPU comparisons were performed: Microsoft Flight Simulator, Shadow of the Tomb Raider, Monster Hunter World, Metro Exodus, The Witcher 3: Wild Hunt, Control, Hitman 3, Half-Life: Alyx, Counter-Strike: Global Offensive (CS GO), League of Legends (LOL), Forza Horizon 4, DOTA 2A, Resident Evil 7 Biohazard, Horizon Zero Dawn, PlayerUnknown's Battlegrounds (PUBG), Ghostrunner, NBA 2K20, Battlefield V.

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 amounts of RAM and different video cards. 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. 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 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 i7-8700 is more energy efficient than the Core i7-7700K as it consumes less power: 95W vs. 65W. Power consumption is particularly important for laptops. Also, when choosing a processor cooling system, it will be useful to know its TDP. It is necessary to count so that the TDP data specified in the cooler specification is 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 the main parameter for you is its performance in multi-threaded mode. In this mode, to reach maximum performance, the processor uses all threads and cores that it has. You will find out this data from the benchmark tables below. Before you take into account the data from these tests, be sure to find out whether the software that you are going to use on your computer can work in 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 processor release date and overclocking capability will be the most helpful. The later the processor is released, 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. If the processor can be overclocked, increasing its performance, then it will continue to maintain maximum FPS in the newest games. Accordingly, 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 i7-7700K is 23% better than Core i7-8700 in terms of CPU frequency. Another difference is that Core i7-8700 has 2 more core than Core i7-7700K. 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 i7-7700K is better: 5
The number of parameters for which Intel Core i7-8700 is better: 27
Although it should be understood that all the data in the text above do not mean that taking them into account you should fully trust a simple comparison of these figures. Better to watch benchmarks video and read the reviews of real owners of Intel Core i7-7700K and Intel Core i7-8700 before making a choice which of the processors to buy for gaming.
