Processor comparisons 11-09-2022

   For example you can't decide which CPU to buy, you can make a decision by looking at the Intel Core i7-1255UL vs Intel Core i9-9900KS tests and decide which is better for games or simple use for video editing, programming, streaming, rendering, machine learning. Here you can find all information from real streaming and video editing tests or many benchmarks. A careful analysis of all the technical characteristics, to make it easier to understand, is made by the table.
   From the comparison video, you can get the results of joint testing in synthetic type tests like World of Tanks enCore Benchmark, Cinebench 23 (20, 15), Furmark, RealBench, 3DMark, MATLAB, Blender, VeraCrypt, PassMark, UserBenchmark, Gears 5, WPrime, Handbrake, Dolphin Emulator, SuperPi, PCMark 10, AIDA64, 7zip, DaVinci Resolve Studio, Prime95, Blender, GeekBench 6, 5.2.

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 run 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, just 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 that were in the comparisons not only did they have 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. You will get more accurate information about how powerful 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 finishing resolution 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 i7-1255UL is more energy efficient than the Core i9-9900KS as it consumes less power: 15W vs. 127W. 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 plan to use the processor not only for gaming, but also for streaming, programming, machine learning, video rendering or video editing, then first of all you need to pay attention to the performance in multi-threaded mode. In this mode, the CPU uses all cores and threads 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 check whether the program 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 advantages of multi-core mode are unused.

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 newer the processor, 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. When the processor can be overclocked, increasing its performance, then it will continue to maintain maximum FPS in the newest games. The economy 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 i9-9900KS is 57% better than Core i7-1255UL in terms of CPU frequency. Another difference is that Core i7-1255UL has 2 more core than Core i9-9900KS. 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 i7-1255UL is better: 12
The number of parameters for which Intel Core i9-9900KS is better: 21
Although it should be understood that all the number in the table above do not mean that taking them into account you should totally trust a simple quantitative comparison. Better to watch benchmarks video and read the opinion of of people who bought Intel Core i7-1255UL and Intel Core i9-9900KS before making a choice which of the processors to buy for gaming.
