When people hear “powerful server”, most imagine a CPU with as many cores as possible. That makes sense for web apps or databases. Game servers work differently – and that’s exactly why we chose the AMD Ryzen 9 7950X3D for our primary location in Poland.
A game server is a single-core race
Most game servers have a main loop (the game loop, or tick). Every few milliseconds it calculates everything happening in the game – player movement, entities, physics, redstone, scripts. This loop runs mostly on a single thread.
- Minecraft runs 20 ticks per second, which means a budget of 50 ms per tick. If the server can’t finish a tick in time, TPS drops and players see lag.
- FiveM servers handle entity synchronisation and hundreds of scripts – single-core speed matters here too.
- Rust tracks “server FPS”, which drops as buildings and entities pile up over a wipe.
- DayZ simulates a central economy, zombies and loot across a huge map.
Dozens of slow server-grade cores don’t help much here. What matters is single-core clock speed and how quickly the CPU can reach its data.
What 3D V-Cache is and why it matters
The Ryzen 9 7950X3D has 16 cores / 32 threads, a boost of up to 5.7 GHz and, most importantly, 128 MB of L3 cache. A large part of it is 3D V-Cache – an extra layer of cache stacked directly on top of the core chiplet.
Why does that matter? Game servers constantly touch huge amounts of small data – entities, chunks, player state. If that data doesn’t fit in cache, the CPU has to wait for main memory, which is orders of magnitude slower. A big L3 cache means less waiting and a steadier tick – even when the server is full.
In practice: steadier Minecraft TPS, a smoother FiveM city during the evening peak and higher server FPS on Rust wipe day.
Two chiplets, two strengths
The 7950X3D has two chiplets (CCDs). One carries the 3D V-Cache, the other runs at higher clocks. Game servers can benefit from both the huge cache and the high frequency. We tune our setup so game processes make the most of the CPU’s strengths.
What else matters for performance
The CPU is the foundation, but not everything:
- Fast DDR5 memory – lower latency and more bandwidth for big worlds.
- NVMe SSDs – fast chunk loading, backups and server starts.
- Sensible density – we don’t overload machines, so neighbours don’t steal your performance.
- Attack protection – the best CPU won’t help if a DDoS floods the server. That’s why we run our own anti-DDoS protection.
Summary
For game servers: a fast core + a big cache > many slow cores. The Ryzen 9 7950X3D is one of the best CPUs you can put into game hosting today. Check out our plans or the detailed hardware page.
