Intel Pentium Gold G6400 vs Intel Core i7-6660U

Processor comparisons   11-09-2022
   For example you can't decide which CPU to buy, you can make a choice after reading the comprehensive tests Intel Pentium Gold G6400 vs Intel Core i7-6660U and decide which is better for games or normal use for machine learning, programming, streaming, rendering, video editing. Here is useful information from many benchmarks or real video editing and streaming tests. A thorough analysis of all the technical characteristics, to make it easier to understand, is summarized in the table.
   From the comparison video, you can get the results of parallel examination in synthetic type tests like GeekBench 6, 5.2, UserBenchmark, 3DMark, DaVinci Resolve Studio, VeraCrypt, PassMark, PCMark 10, Gears 5, Dolphin Emulator, World of Tanks enCore Benchmark, SuperPi, Blender, 7zip, RealBench, Furmark, AIDA64, Handbrake, Prime95, WPrime, Cinebench 23 (20, 15), MATLAB, Blender.

For the maximum in this test, the results of the most powerful processor in the site database are taken. And it is clear that 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 small game result, 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 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 Core i7-6660U is more energy efficient than the Pentium Gold G6400 since it has less power consumption: 58W vs. 15W. Power consumption is especially 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

If you want to use the processor not only for gaming, but also for programming, video rendering or video editing, machine learning, streaming, then the main parameter for you is its performance in multi-threaded mode. In this mode, the processor 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 you take into account the data from these tests, be sure to check whether the software you are going to use on your computer supports multi-threaded mode. Because there are still many programs that can use only one core to run, and all the benefit of multi-core mode are unused.

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.
