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 the cost of this processor reaches several tens of thousands of dollars. And if it seems to you that the selected CPU has a low 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 tested computers 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 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. 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 G6405T as it consumes less power: 15W vs. 35W. 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

Let's say you plan to use the processor not only for gaming, but also for video rendering or video editing, programming, machine learning, streaming, then the main parameter for you is its performance in multi-threaded mode. In this mode, the CPU uses all threads and cores that it has to the maximum to achieve maximum efficiency. You will learn this data from the benchmark tables below. Before using the data from these tests, be sure to find out whether the program 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 benefit of multi-core mode turns out to be unnecessary.

Comparison of specifications

In the specification comparison table, the processor release date and overclocking capability will be the most helpful. The later the processor is released, the longer it will last in your computer. 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 in the newest games. Accordingly, there is no longer a 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 Pentium Gold G6405T is 31% better than Core i7-6660U in terms of CPU frequency. 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 i7-6660U is better: 7
The number of parameters for which Intel Pentium Gold G6405T is better: 23
However, it should be realized that all the figures in the text above do not mean that you should be guided entirely by them and trust a simple quantitative comparison. Better to watch the testing video and read the reviews of of people who bought Intel Core i7-6660U and Intel Pentium Gold G6405T before deciding which CPU to buy for gaming and which not.
