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 this processor costs several tens of thousands of dollars. And if it seems to you that the selected CPU has a low 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 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, 4K or FullHD. 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 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. The newer the processor generation, the better its performance in games and benchmarks, as well as its energy efficiency. In this case the Core i9-11900KB is more energy efficient than the Xeon W-3275M as it consumes less power: 65W vs. 205W. 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

Let's say you plan to use the processor not only for gaming, but also for video rendering or video editing, machine learning, programming, streaming, then the main parameter for you is its performance in multi-threaded mode. In this mode, the CPU uses all cores and threads that it has to the maximum to reach maximum performance. You will learn this data from the benchmark tables below. Before using 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 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 most useful will be the release date of the processor and the possibility of overclocking it. The newer the processor, the longer it will last in your computer. And the easier it will be to upgrade the system later. 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 in the newest games. The savings are obvious! Accordingly, there is no longer a need to buy a new CPU to enjoy the games any longer.

Part number

In this comparison block, you should pay attention to the differences in clock speed and the number of cores. Here Core i9-11900KB is 24% better than Xeon W-3275M in terms of CPU frequency. Another difference is that Xeon W-3275M has 20 more core than Core i9-11900KB. 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 i9-11900KB is better: 16
The number of parameters for which Intel Xeon W-3275M is better: 20
However, it should be realized 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 comparison of these numbers. Better to watch the testing video and read the opinion of real owners of Intel Core i9-11900KB and Intel Xeon W-3275M before making a selection which of the CPUs to buy for gaming.
