Game Server Hardware Selection Guide: Matching CPU, RAM, and Storage to Your Player Count

Selecting hardware for a game server is about matching specs to your specific player count and game type. What works for a 10-player Valheim server will not support a 100-player Rust server, and the hardware that handles a vanilla Minecraft server is different from what you need for a modded pack with 200+ mods. This guide provides concrete hardware recommendations based on player count, game engine, and workload type.

CPU: Cores vs Clock Speed by Game Type

Game servers fall into two categories when it comes to CPU requirements. Single-thread-bound games (Minecraft, Factorio, Valheim, Terraria, RimWorld) benefit most from high clock speed and strong IPC — a 6-core CPU with a 5.0 GHz boost clock will outperform a 16-core CPU at 3.0 GHz for these titles. Multi-threaded games (ARK, Palworld, Rust, 7 Days to Die, Enshrouded) can utilize multiple cores, especially for physics, AI pathfinding, and world simulation.

Player Count	Recommended CPU (Single-Thread Games)	Recommended CPU (Multi-Thread Games)
1–20 players	4 cores @ 4.5 GHz+ (Core i5 / Ryzen 5)	6 cores @ 4.0 GHz+ (Core i5 / Ryzen 5)
20–50 players	6 cores @ 5.0 GHz+ (Core i7 / Ryzen 7)	8 cores @ 4.5 GHz+ (Core i7 / Ryzen 7)
50–100 players	8 cores @ 5.0 GHz+ (Core i9 / Ryzen 9)	12–16 cores @ 4.5 GHz+ (Xeon / EPYC)
100+ players	8–12 cores @ 5.0 GHz+ (i9 / Xeon)	16–24 cores @ 4.0 GHz+ (EPYC / Xeon Gold)

RAM: How Much You Actually Need Per Game

RAM requirements vary dramatically by game. The table below shows baseline allocations for smooth gameplay, excluding operating system overhead (add 2–4 GB for the OS).

Game	10 Players	30 Players	50 Players	100 Players
Minecraft (Vanilla)	4 GB	8 GB	12 GB	16 GB
Minecraft (Modded)	8 GB	12 GB	16 GB	24 GB
Palworld	8 GB	12 GB	16 GB	32 GB
ARK: Survival Ascended	8 GB	16 GB	24 GB	48 GB
Rust	6 GB	10 GB	16 GB	32 GB
Valheim	4 GB	6 GB	8 GB	12 GB
7 Days to Die	6 GB	10 GB	16 GB	24 GB
Enshrouded	8 GB	12 GB	20 GB	32 GB

Storage: Matching Drive Type to Workload

Storage requirements depend on the game’s world save mechanics. Games that save the entire world state periodically (Minecraft, ARK, 7 Days to Die) benefit from NVMe with high random write IOPS. Games that save incrementally (Palworld, Valheim) are less demanding but still benefit from NVMe for chunk loading during gameplay.

Minimum storage recommendations:

• Minecraft: 100 GB base + 10 GB per 10 players for world files
• ARK: 200 GB base + 50 GB per map for save files
• Rust: 100 GB base + 20 GB per wipe cycle
• Palworld: 50 GB base + 5 GB per 10 players
• Valheim: 20 GB base (worlds are small)

Always allocate 20–30% extra storage for backups, mods, and log files. Enterprise NVMe with 1 DWPD endurance is recommended for any server with 30+ players or frequent auto-save intervals.

Network: Bandwidth and Port Speed

A single game server instance uses 50–200 Mbps depending on player count and game type. A 1 Gbps port is sufficient for most scenarios. Upgrade to 10 Gbps when running multiple game instances on the same machine (5+ servers) or when hosting a popular server that regularly hits 80+ concurrent players.

When evaluating game server hosting plans, use the tables above as a baseline and add 20% headroom for peak usage. Hardware that meets these thresholds will deliver stable performance, smooth tick rates, and a positive experience for your players.
