The maximum result in this parameter is 100 percent, which is the performance of the most powerful processor currently available. 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. Therefore, if you think that the selected CPU has a low 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 comparisons not only were the equipped with different amounts of RAM and different video cards. But users also tested them at different screen resolutions: 2K, FullHD 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 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. The newer the processor generation, the better its performance in games and benchmarks, as well as its energy efficiency. In this case the Core i5-12450HX is more energy efficient than the Core i9-7920X as it consumes less power: 55W vs. 140W. Power consumption is especially important for laptops. And TDP should be taken into account when choosing a processor cooling system. It is necessary to calculate so that the TDP data specified in the cooler specification is greater than the TDP of the compared processor.

Software benchmarks

For example you want to use the processor not only for gaming, but also for streaming, programming, machine learning, video editing or video rendering, then first of all you need to pay attention to the performance in multi-threaded mode. In this mode, the CPU includes all threads and cores that it has to the maximum to reach 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 software that you are going to use on your computer can work in multi-threaded mode. Because there are still many programs that 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 most useful will be the the possibility of overclocking it and release date of the processor. The later the processor is released, 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 still be able to produce maximum FPS in new games. Accordingly, you do not 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 Core i5-12450HX is 6% better than Core i9-7920X in terms of CPU frequency. Another difference is that Core i9-7920X has 4 more core than Core i5-12450HX. 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 i5-12450HX is better: 14
The number of parameters for which Intel Core i9-7920X is better: 18
However, it should be understood that all the figures in the table above do not mean that you should be guided entirely by them and trust a simple comparison of these figures. Better to watch the video tests and read the reviews of real owners of Intel Core i5-12450HX and Intel Core i9-7920X before making a selection which of the CPUs to buy for gaming.
