Why CPU Frequency is Important ?

When it comes to Minecraft server hosting, having a low latency server is crucial to ensure smooth gameplay for all players. One important factor that affects latency is the CPU frequency, which refers to the speed at which the CPU processes data. In this guide, I'll explain why CPU frequency is important and why the AMD Ryzen 3900X is one of the best solutions for Minecraft server hosting.

Why CPU Frequency is Important for Low Latency Minecraft Server Hosting

CPU frequency plays a critical role in determining the performance of a Minecraft server. The faster the CPU can process data, the faster it can respond to requests from players, resulting in a lower latency gaming experience.

When players connect to a Minecraft server, the server has to process a lot of data, including player movements, interactions with the environment, and player-to-player interactions. If the CPU frequency is too slow, the server will struggle to keep up with the demands of all players, resulting in lag and high latency.

Frequency impact on Java Minecraft server process

Java is an object-oriented programming language that is used in many applications, including Minecraft servers. One of the reasons why Java likes high frequency is because of the way it handles memory management.

When a Java program runs, it uses a portion of the computer's memory to store and manipulate data. As the program runs, it creates new objects and data structures in memory, and these objects need to be moved around and cleaned up when they are no longer needed.

To manage this memory, Java uses a process called garbage collection. Garbage collection involves periodically scanning the memory to identify objects that are no longer needed and removing them from memory. This process can be resource-intensive and can cause delays in the program's execution.

When Java runs on a CPU with a high frequency, it can perform garbage collection more quickly and efficiently. This is because the CPU can process data more quickly, allowing Java to scan the memory and identify unnecessary objects more rapidly. As a result, the program can free up memory more quickly, which can improve overall performance and reduce latency.

In addition to garbage collection, Java also benefits from a high-frequency CPU because it can perform other tasks more quickly as well. For example, Java programs may need to perform complex calculations or manipulate large amounts of data. A high-frequency CPU can perform these tasks more quickly, resulting in faster program execution and improved overall performance.

Difference Between CPU Generations Before the AMD Ryzen 3900X

Before the AMD Ryzen 3900X, Intel was the go-to option for high-performance CPUs for Minecraft server hosting. However, Intel CPUs tended to have lower core counts and slower clock speeds than their AMD counterparts. This meant that Intel CPUs struggled to keep up with the demands of Minecraft servers with many players, resulting in higher latency.

The AMD Ryzen 3900X is one of the best solutions for low latency Minecraft server hosting. It features a 12-core, 24-thread design, which means it can handle a large number of players and processes data quickly. It also has a base clock speed of 3.8 GHz and can boost up to 4.6 GHz, providing plenty of CPU frequency to keep up with the demands of Minecraft servers.

In addition to its high core count and fast clock speeds, the AMD Ryzen 3900X also has a large amount of L3 cache. This cache helps the CPU to store frequently accessed data, which can significantly reduce latency and improve overall server performance.

CPU performance comparisons using the PassMark CPU benchmark

  1. Ryzen 9 3900X - PassMark score of 25,101
  2. Intel Core i9-10900K - PassMark score of 21,738
  3. Intel Core i9-9900K - PassMark score of 17,885
  4. Intel Xeon E5-2697 v2 - PassMark score of 17,176
  5. AMD Ryzen 7 2700X - PassMark score of 16,500
  6. Intel Core i7-9700K - PassMark score of 15,664

It's important to note that other factors such as clock speed, core count, cache size, and overall system configuration can also impact the performance of the CPU in a Minecraft server hosting environment.


In summary, CPU frequency is a crucial factor in providing low latency Minecraft server hosting. The AMD Ryzen 3900X is an excellent solution for this, thanks to its high core count, fast clock speeds, and large L3 cache. By choosing the right CPU, you can ensure that your Minecraft server delivers smooth and lag-free gameplay for all players.
