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 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 amounts of RAM and different video cards. 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 get acquainted with the benchmarks that are made with the same video card that is installed in your computer.

To make a finishing choice 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 i7-8500Y is more energy efficient than the Core i7-6660U as it consumes less power: 15W vs. 5W. Power consumption is particularly 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

For example you plan to use the processor not only for gaming, but also for programming, video editing or video rendering, machine learning, streaming, then the main parameter for you is its performance in multi-threaded mode. In this mode, to reach maximum efficiency, the processor uses 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 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 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 useful will be the the possibility of overclocking it and release date of the processor. The newer the processor, the longer it will last in your computer. And the easier it will be to upgrade the system in the future. The same can be said about overclocking. If the processor can be overclocked, thereby increasing its performance, then it will continue to maintain maximum FPS even in new games. The economy are obvious! Accordingly, there is no longer a need to buy a new CPU to enjoy the games any longer.

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 i7-6660U is better: 22
The number of parameters for which Intel Core i7-8500Y is better: 7
However, it should be understood that the summary 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 the testing video and read the reviews of real owners of Intel Core i7-6660U and Intel Core i7-8500Y before making a selection which processor to buy for gaming and which not.
