Intel Xeon W-10855M vs Intel Core i7-6900K

Processor comparisons   27-07-2021
   For example you can't decide which processor to buy, you can make a choice by looking at the Intel Xeon W-10855M vs Intel Core i7-6900K tests and see which is better for games or normal use for streaming, programming, machine learning, rendering, video editing. Here is all information from many benchmarks or real streaming and video editing tests. A step-by-step analysis of all the technical characteristics, so that it can be easier to read, is presented in the form of the table.
   From the video comparison, you can get the results of joint testing in synthetic type tests like Cinebench 23 (20, 15), Dolphin Emulator, GeekBench 6, 5.2, Blender, SuperPi, PassMark, AIDA64, RealBench, MATLAB, Blender, WPrime, UserBenchmark, Furmark, VeraCrypt, 7zip, Prime95, DaVinci Resolve Studio, PCMark 10, 3DMark, World of Tanks enCore Benchmark, Gears 5, Handbrake.
   And how good the CPUs are in games:

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 play games. Because this processor costs several tens of thousands of dollars. And if it seems to you 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 participating in the comparing not only were the equipped with different video cards and different amounts of RAM. But users also tested them at different screen resolutions: 2K, FullHD 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 compare it in one assembly with the 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. 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-10855M is more energy efficient than the Core i7-6900K as it consumes less power: 45W vs. 140W. 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 machine learning, streaming, programming, video rendering or video editing, 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 achieve maximum performance. You will learn this data from the benchmark tables below. Before using the data from these tests, be sure to check whether the program you are going to use on your computer supports multi-threaded mode. Since 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 release date of the processor and the possibility of overclocking it. The later the processor is released, the longer it will last you. 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 even in new 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 i7-6900K is 12% better than Xeon W-10855M in terms of CPU frequency. Another difference is that Core i7-6900K has 2 more core than Xeon W-10855M. 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-10855M is better: 10
The number of parameters for which Intel Core i7-6900K is better: 23
Although it should be understood that the summary data in the article above do not mean that taking them into account you should fully trust a simple comparison of these numbers. Be sure to watch benchmarks video and read the opinion of of people who bought Intel Xeon W-10855M and Intel Core i7-6900K before making a selection which processor to buy for gaming and which not.
