The maximum result in this parameter is 100 percent, which is the performance of the most powerful processor currently available. 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. And if it seems to you 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 processors were compared: DOTA 2A, Battlefield V, NBA 2K20, Monster Hunter World, Metro Exodus, Half-Life: Alyx, Hitman 3, Counter-Strike: Global Offensive (CS GO), The Witcher 3: Wild Hunt, Horizon Zero Dawn, League of Legends (LOL), PlayerUnknown's Battlegrounds (PUBG), Control, Forza Horizon 4, Microsoft Flight Simulator, Shadow of the Tomb Raider, Ghostrunner, Resident Evil 7 Biohazard.

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 final 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 Xeon W-11855M is more energy efficient than the Core i7-7820X since it has less power consumption: 45W vs. 140W. Power consumption is especially important for laptops. And TDP should be taken into account when choosing a processor cooling system. 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

For example you plan to use the processor not only for gaming, but also for video rendering or video editing, streaming, machine learning, programming, then the main parameter for you is its performance in multi-threaded mode. In this mode, to reach maximum efficiency, the processor includes all cores and threads that it has. You will learn this data from the benchmark tables below. Before using the data from these tests, be sure to make sure that the program 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 work, 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 useful. 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 can be said about overclocking. If the processor can be overclocked, increasing its performance, then it will still be able to produce maximum FPS even in the newest games. Accordingly, you do not 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 i7-7820X is 11% better than Xeon W-11855M in terms of CPU frequency. Another difference is that Core i7-7820X has 2 more core than Xeon W-11855M. 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 Xeon W-11855M is better: 12
The number of parameters for which Intel Core i7-7820X is better: 21
However, it should be realized that the summary data in the table above do not mean that taking them into account you should entirely trust a simple comparison of these figures. Better to watch benchmarks video and read the reviews of real owners of Intel Xeon W-11855M and Intel Core i7-7820X before making a choice which processor to buy for gaming and which not.
