The maximum result in this parameter is 100 percent, which is the performance of the most powerful processor at the moment. 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. 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 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 tested computers not only did they have different video cards and different amounts of RAM. But users also tested them at different screen resolutions: FullHD, 2K 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 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 i7-1265U is more energy efficient than the Core i9-9900K since it has less power consumption: 15W vs. 95W. 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

For example you plan to use the processor not only for gaming, but also for programming, video rendering or video editing, streaming, machine learning, then the main parameter for you is its performance in multi-threaded mode. In this mode, the processor includes all threads and cores that it has to the maximum to reach maximum performance. You will find out this data from the benchmark tables below. Before using 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. Because there are still many programs that can use only one core to work, and all the advantages of multi-core mode turns out to be unnecessary.

Comparison of specifications

In the specification comparison table, the most helpful will be the the possibility of overclocking it and release date of the processor. The newer the processor, the longer it will last you. And the easier it will be to upgrade the system in the future. The same benefits from the presence of overclocking. When the processor can be overclocked, thereby increasing its performance, then it will still be able to produce maximum FPS even in the newest games. The savings 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. Here Core i9-9900K is 50% better than Core i7-1265U in terms of CPU frequency. Another difference is that Core i7-1265U has 2 more core than Core i9-9900K. 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 i7-1265U is better: 13
The number of parameters for which Intel Core i9-9900K is better: 20
However, it should be understood that all the figures that you have looked at here do not mean that you should be guided entirely by them and trust a simple quantitative comparison. Better to watch the video tests and read the reviews of real owners of Intel Core i7-1265U and Intel Core i9-9900K before making a selection which of the CPUs to buy for gaming.
