The maximum result in this parameter is 100 percent, which is the performance of the most powerful processor at the moment. 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. Therefore, if you think that the selected CPU has a small game result, just 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 tested computers not only did they have different video cards and different amounts of RAM. But users also tested them at different screen resolutions: FullHD, 2K or 4K. 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 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 i7-1265UE is more energy efficient than the Core i7-1255U as it consumes less power: 15W vs. 15W. Power consumption is especially important for laptops. Also, when choosing a processor cooling system, you need 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 plan to use the processor not only for gaming, but also for machine learning, programming, video editing or video rendering, streaming, then first of all you need to pay attention to the performance in multi-threaded mode. In this mode, to achieve maximum efficiency, the CPU turns on all threads and cores 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 run, 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 helpful. 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. When the processor can be overclocked, increasing its performance, then it will still be able to produce maximum FPS in new games. Accordingly, there is no longer a need to buy a new CPU to enjoy the games any longer. The economy are obvious!
