What is the difference between RAM and Cores

That's really how important the number of CPU cores is

Friedrich Stiemer

Many CPU cores also bring a lot of performance. What sounds so simple is actually more complicated. The tip explains when many cores are worthwhile and when they are not.

EnlargeUnder the hood: An 8-core CPU of the AMD Ryzen generation is currently less worthwhile for gaming, but more so for multimedia tasks.

In March 2017, AMD launched its new generation of CPUs called Ryzen. It starts with the Ryzen 7 generation, which now functions as the manufacturer's new upper class. This involves a total of three processors with a whopping eight physical computing cores and the possibility of processing a total of 16 threads in parallel. The cheapest model also costs only 360 euros. For comparison: At Intel, a similarly equipped chip costs over 1000 euros.

This currently unbeatable price-performance ratio has sparked a lively discussion about how many CPU cores actually make sense in practice. Because the opinion is widespread that the number of processor cores determines the performance of a CPU - the more cores, the faster. However, it cannot be defined in such a general way, because you actually have to differentiate from case to case, as we will clarify below.

In PC games, hardly more than four CPU cores are currently required, as the majority of current titles cannot support more cores. But gradually the development progresses and the majority of gaming studios are programming their upcoming games in such a way that they make optimal use of the resources of hexa- and octa-core processors. Thus, the statement can be made that buying models with more than four cores is an investment in the future.

CPU unleashed: overclocking made easy

As tests show, when it comes to gaming performance, the new Ryzen 7 CPUs only do almost as well as four-core models from Intel, because the latter offer much higher clock frequencies - currently still the decisive factor in games. However, gamers should not lose sight of the fact that the graphics card is the main factor in determining a high frame rate.

More CPU cores are also worthwhile for users who do a lot of multi-tasking, i.e. who have many applications open at the same time. A typical scenario would be a setting with two monitors: the game is running on the main screen, while the browser is open on the other screen, the voice chat tool is active and the game may even be recorded with another program or even streamed live . Here, too, more than four cores have an extremely positive effect.

Multimedia also speaks in favor of more than four CPU cores: Anyone who does a lot of 3D rendering and video processing (e.g. editing and coding) or who often deals with high-resolution audio files will benefit from more cores instead of high clock rates. Because these processes are multi-core-optimized and always distribute the load to all available computing cores.
