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 this processor costs 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.

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: 4K, 2K or FullHD. 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 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 i5-6500 is more energy efficient than the Core i7-6700K since it has less power consumption: 65W vs. 95W. 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

Let's say you want to use the processor not only for gaming, but also for programming, streaming, machine learning, video editing or video rendering, then the main parameter for you is its performance in multi-threaded mode. In this mode, to reach maximum efficiency, the CPU turns on all threads and cores that it has. 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 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 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 i7-6700K is 19% better than Core i5-6500 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 i5-6500 is better: 2
The number of parameters for which Intel Core i7-6700K is better: 25
However, it should be realized that all the data in the text above do not mean that you should be guided entirely by them and trust a simple comparison of these figures. Be sure to watch benchmarks video and read the opinion of real owners of Intel Core i5-6500 and Intel Core i7-6700K before deciding which processor to buy for gaming and which not.
