I mean not only 6 Game Launcher but also GHub from Logitech, most Firefox with more than 5 tabs in 2 windows, the AMD Radeon software, GPU Tweak, Spotify, Oculus Tray Tool etc. are running in the background. They also need performance.

First of all … why does it all have to work?
And secondly … Yes, the required power, so should run as little as possible in order to have the best possible performance in games.Regardless of whether you have enough RAM for everything and your CPU still has reserves besides the game …. Everything that is running on the side can be a hindrance … Especially because the other programs keep bringing their own data into the CPU caches and with it Game data throws out …
As the title suggests, it’s about singelcore performance. I keep hearing that it is better in games when the single core performance is high. But what I’m wondering all the time is what is the rest of the system doing in the background?

I think this is a common generalization that confuses you.
More precisely, one had to say that the game performance (in the CPU limit) is often dominated by the processing power of the CPU core, which is currently processing the main thread of the game … And that is also a strong generalization.
Take a modern 8 core … and ignore that most of them have 16 threads.
Benchmarks such as cinebench can use it to full capacity, as they assign independent tasks to each thread, most of which fit into the CPU cache …. Each thread can work independently and hardly has to wait for the RAM or other threads.
The CPU gets particularly warm here, etc. and the modern boost variants lower the clock rate … You can find a “multicore performance” (for this program).I can also instruct Cinebench to only use one thread.
The boost will be higher here … And one core provides more than 1/8 of the mc performance …. We have found the single thread performance.It’s a lot more difficult with games … Others have already described it …. multithreading is problematic with the many dependencies ….. A thread must ensure that everything fits chronologically and that the work is distributed, merged and much more more.
In the meantime, 4-7 CPU cores are often actually used … The consumption is higher than with a thread in Cinebench … And with that, the clock rate and the performance of the CPU core, which is currently processing the main thread, also decrease.And communication also takes time … And there are a lot more RAM accesses than with Cinebench … etc.
So the situation is much more complex and actually cannot be compared with “single core performance”.
Nevertheless, many draw the comparison, since CPUs with more cores / threads increase the mc performance significantly and that does not help in games to the same extent.
The sc performance often correlates better with the game performance.In my opinion, this is not a generally valid connection … More like a farmer’s rule that applies more often.
