If you’ve ever wondered why some Minecraft servers run buttery smooth while others lag with just a few players, the answer often comes down to one thing: the CPU.
Let’s break down what that means, why it matters, and which CPUs actually perform best for Minecraft servers in 2025.
Minecraft (both Java & Bedrock) is famously CPU-intensive because the game world, redstone ticks, mob AI, physics, and chunk generation, is processed on the server’s main thread. This means your CPU’s speed, not just memory, directly controls how smooth your server runs.
What is a CPU?
The CPU (Central Processing Unit) is like the “brain” of your computer or server. It’s the part that does all the thinking, it takes instructions (from programs, Minecraft server software, or plugins) and processes them really, really fast.
Why CPU is Important For Minecraft Servers?
A better CPU makes a direct and noticeable difference in how a Minecraft server performs. Minecraft's server software is limited mostly by single-thread performance, meaning that one thread of your CPU is doing most of the important work, such as world ticking, entity updates, redstone logic, and chunk loading.
When you have a CPU with higher single-core speed and better efficiency (measured as instructions per clock, or IPC), the server can process those tasks faster and keep a stable tick rate.
What happens in Minecraft if you have a better CPU?
In practical terms, upgrading to a stronger CPU results in much faster startup and smoother gameplay. For example:
A Paper server might start in just 15 seconds on a AMD Ryzen 7 5800X, compared to 25–30 seconds on a AMD Ryzen 7 3800X. The difference comes from both the slightly higher clock speed and added efficiency of newer CPUs.

Chunk generation is also noticeably quicker (usually about 20 to 25 percent faster) which means fewer lag spikes when players explore new terrain.

A better CPU can also handle more players before the tick rate starts to drop. A 3800X might begin to lose TPS (ticks per second) with 18 to 20 players, while a 5800X can typically handle 25 to 30 players at a stable 20 TPS.

In short, a faster CPU doesn’t just look better on paper, it makes the server start quicker, run smoother, and support more players without lag.
Best CPUs For Minecraft Servers
So the big question: What are the best CPUs? Here's a quick table overview of everything we recommend going with:
Tier | CPU Models | Performance | Note |
---|---|---|---|
💎 Top-Tier | Ryzen 7 7800X3D, Ryzen 7 5800X3D | ⭐⭐⭐⭐⭐ | The best CPUs for Minecraft servers. |
✨ High-End | Ryzen 9 7950X3D, Ryzen 9 9950X3D | ⭐⭐⭐⭐ | More cores, same single-thread speed as the 7800X3D. Slightly higher power use and cost. |
🍀 Balanced / Cost-Efficient Tier | Ryzen 7 5800X, Ryzen 5 5600, Ryzen 7 7700 | ⭐⭐⭐⭐ | The best value options. |
🏡 Home / DIY Servers | Ryzen 5 5600, Ryzen 5 7600, Ryzen 7 5700X | ⭐⭐⭐ | Ideal entry-level CPUs |
In 2025, AMD CPUs are the clear choice for Minecraft servers. While Intel still produces solid consumer chips, they’ve fallen behind for Minecraft hosting due to:
- Weaker single-core efficiency
- Hardware instabilities and microcode issues that affect uptime.
- Higher platform cost (motherboards + power draw + cooling).
❌ Why We Don’t Recommend Intel or Xeon CPUs
You've probably seen a lot of Intel and Xeons being used by hosting providers and this question comes up often, so let’s be clear:
CPU Family | Why It’s Not Ideal for Minecraft |
---|---|
Intel Core (i5, i7, i9) | Strong on paper, but weaker in Minecraft’s single-threaded workloads. Runs hotter, draws more power, and costs more for similar tick performance. |
Intel Xeon (E, Silver, Gold) | Built for multi-core workloads like virtualization or databases. Minecraft barely uses extra cores, so performance per player drops fast as world complexity increases. |
Older Xeon E5 / v4 CPUs | Common in cheap hosts, but outdated and slow. Great for web servers, terrible for Minecraft. |
Always Optimize Your CPU Performance
Before you rush to upgrade your hardware, it’s worth knowing that you can get a huge performance boost just by optimizing your software and setup. Even the best CPUs, like the Ryzen 7 7800X3D, can struggle if the server software or environment isn’t tuned properly.
- Don't use the default Mojang server (Vanilla). Use an optimized server software such as Paper or Purpur.
- Use proper JVM Flags (Aikar's Flags). Using Aikar’s recommended startup flags helps Minecraft’s garbage collector work smarter, reducing lag spikes and keeping tick times stable.
- Keep your system, BIOS, and firmware updated.
- Remove unnecessary plugins and mods. Every plugin or mod you add increases the CPU’s tick workload.
- Use fast SSD storage and low-latency RAM.
Conclusion
If you take one thing away from this guide, let it be this:
Minecraft servers don’t need more cores, they need faster ones. AMD Ryzen X3D CPUs are the best processors for Minecraft servers.
That’s why hosts like WiseHosting build their systems around high-frequency AMD Ryzen CPUs, not around cheap or outdated hardware.
Whether you’re running a small SMP or a community server with hundreds of players, the Ryzen 7 5800X3D and 7800X3D deliver unmatched tick performance and reliability.
And if you’re buying your server from WiseHosting, you’re likely using them.
