Minecraft Server Requirements 2026: Exact RAM, CPU and Storage
Verdict: For a normal 10-player vanilla server, budget 6-8 GB RAM, a 3.5 GHz+ CPU, and NVMe storage. For modpacks like ATM10, start at 12-16 GB RAM.
Beginner Shortcut
If you are new and just want a safe answer, use this rule.
| What you are running | Start here |
|---|---|
| 2 to 5 friends, vanilla | 3 GB RAM |
| 5 to 15 friends, Paper | 4 to 6 GB RAM |
| 10 to 25 players, plugins | 6 to 8 GB RAM |
| Better MC or RLCraft | 8 to 12 GB RAM |
| ATM10 | 12 to 16 GB RAM |
| Public SMP with farms | 8 GB RAM or more |
RAM is only half the story. A slow CPU can lag with plenty of RAM left unused. For Minecraft, a faster core is usually better than many slow cores.
What Beginners Should Not Overthink
You do not need a giant server for a new world. Start with the right size for the next month, not the dream player count. You can upgrade when the Discord grows.
The things that matter first are:
- Enough RAM for the server type.
- A fast CPU core.
- NVMe storage.
- Backups before big changes.
- A location close to most players.
If your friends are in Europe, pick a Netherlands server. If most are in North America, pick Canada. Latency is simple: closer usually feels better.
If you are setting up a Minecraft server in 2026, the right hardware is not optional. Modern Minecraft (Java 21, Paper, NeoForge, big modpacks) is significantly more demanding than what worked even two years ago.
This guide gives you exact numbers for RAM, CPU, storage, and bandwidth based on what you actually plan to run, from a 5 player vanilla world to a 50 player ATM10 server. If your players are in Europe, compare Minecraft server hosting in the Netherlands.
Quick Answer: Minecraft Server Specs by Player Count
| Target server | Practical 2026 spec |
|---|---|
| 10-player vanilla or Paper | 3-4 GB RAM, fast 2-core CPU, NVMe preferred |
| 20-player Paper with plugins | 6-8 GB RAM, high-clock Ryzen/i7 class CPU, NVMe |
| 50-player Paper/Purpur | 10-16 GB RAM, strong single-core CPU, tuned view distance |
| ATM10 or large modpack | 12-18 GB RAM for most groups, Java 21, NVMe, backup headroom |
If you are unsure, buy for the next tier up instead of the current player count. Minecraft lag usually appears when chunks, entities, backups, and plugins spike at the same time.

2. RAM Requirements Explained
How Much RAM Does Minecraft Server Need?
RAM stores world data, player positions, loaded chunks, entities (mobs/items), and plugin/mod data. Insufficient RAM causes:
- Slow chunk loading
- TPS drops below 20
- Frequent garbage collection pauses
- Out of memory crashes
RAM by Player Count (Vanilla)
| Players | RAM Needed | Why |
|---|---|---|
| 1-5 | 1-2GB | Minimal loaded chunks, few entities |
| 5-10 | 2-4GB | Moderate chunk spread, plugin overhead |
| 10-20 | 4-6GB | Large render distances, multiple biomes |
| 20-50 | 6-10GB | Massive world exploration, many entities |
| 50-100 | 10-18GB | Requires optimization + Purpur/Paper |
| 100-200 | 18-32GB | Multiple worlds, extensive plugin ecosystem |
RAM Overhead (Plugins vs Mods)
Plugins (Spigot/Paper):
- 10-15 plugins: +1-2GB RAM
- 20-30 plugins: +2-4GB RAM
- 50+ plugins: +4-8GB RAM
Mods (Forge/Fabric):
- 50-100 mods: +2-4GB RAM
- 100-200 mods: +4-8GB RAM
- 200-400 mods (ATM10, Better MC): +8-16GB RAM
Example: Vanilla 10-player server = 4GB. Add 20 plugins = 6-8GB total.
How to Allocate RAM
Correct allocation (Java flags):
java -Xms8G -Xmx8G -jar server.jar nogui
-Xms8G: Minimum RAM (start)-Xmx8G: Maximum RAM (limit)
Set both to same value to prevent resizing lag.
Don't allocate all server RAM: Leave 1-2GB for OS/background processes.
Example: 16GB VPS → allocate 14GB to Minecraft, leave 2GB for system.
3. CPU Requirements (Single-Thread vs Multi-Thread)
Why CPU Speed Matters More Than Core Count
Minecraft's main game loop is single-threaded - runs on 1 CPU core. Fast single-core performance is critical.
Bad: 8-core Intel Xeon @ 2.4GHz (slow single-core)
Good: 4-core AMD Ryzen 5 @ 4.2GHz (fast single-core)
Best: 8-core AMD Ryzen 9 @ 5.4GHz boost (fastest single-core + multi-thread for Paper/Purpur)
Single-Thread Performance Ranking (2026)
| CPU | Boost Clock | Minecraft Performance |
|---|---|---|
| AMD Ryzen 9 7950X | 5.7GHz | Excellent (best) |
| Intel Core i9-14900K | 6.0GHz | Excellent |
| AMD Ryzen 7 7800X3D | 5.0GHz | Great (best price/perf) |
| AMD Ryzen 9 5950X | 4.9GHz | Great |
| Intel Core i7-13700K | 5.4GHz | Great |
| AMD Ryzen 5 5600X | 4.6GHz | Good (budget) |
| Intel Xeon E-2288G | 5.0GHz | Good (server-grade) |
| Intel Xeon Gold 6248R | 4.0GHz | Poor (enterprise, multi-core) |
Recommendation: AMD Ryzen 9 or Intel i9 for 50+ player servers. Ryzen 5/7 for 10-50 players.
Multi-Threading with Paper/Purpur
Paper and Purpur server software add multi-threading for:
- Async chunk loading
- Parallel entity processing
- Multi-threaded lighting updates
Result: 4-8 cores perform better than 2 cores when using Paper/Purpur.
Vanilla/Spigot: Cores beyond 2 provide minimal benefit.
Paper/Purpur: 4-8 cores improve performance 20-40%.
4. Storage: SSD vs NVMe vs HDD
Storage Impact on Performance
Storage speed affects:
- World loading time (server startup)
- Chunk generation speed
- Player login time (loading player data)
- Backup duration
Storage Type Comparison
| Type | Read Speed | Write Speed | Minecraft Impact |
|---|---|---|---|
| HDD | 80-160 MB/s | 80-160 MB/s | Slow chunk gen, 30-60s startup |
| SATA SSD | 500-550 MB/s | 500-520 MB/s | Fast chunk gen, 10-15s startup |
| NVMe SSD | 3,000-7,000 MB/s | 2,000-5,000 MB/s | Instant chunks, 3-5s startup |
Recommendation:
- Vanilla/small servers: SATA SSD sufficient
- Modpacks/large servers: NVMe SSD required (3-5x faster chunk loading)
- Never use HDD: Causes severe chunk gen lag
Storage Space Requirements
| Server Type | Initial Size | After 1 Month | After 6 Months |
|---|---|---|---|
| Vanilla (pre-gen 5k radius) | 3-5GB | 8-12GB | 15-25GB |
| Vanilla (pre-gen 10k radius) | 8-15GB | 20-30GB | 40-60GB |
| Light Plugins | 5-10GB | 15-25GB | 30-50GB |
| Modpack (ATM10) | 15-25GB | 40-70GB | 80-150GB |
| Large Server Network | 50-100GB | 200-400GB | 500GB-1TB |
Tip: Pre-generate world with Chunky plugin to control initial size.
5. Bandwidth and Network Requirements
Upload Bandwidth per Player
Minecraft uses 0.1-0.5 Mbps per player (avg 0.2 Mbps).
| Players | Bandwidth Needed | Recommended |
|---|---|---|
| 5-10 | 1-2 Mbps | 10 Mbps |
| 10-20 | 2-4 Mbps | 25 Mbps |
| 20-50 | 4-10 Mbps | 50 Mbps |
| 50-100 | 10-20 Mbps | 100 Mbps |
| 100-200 | 20-40 Mbps | 200 Mbps |
Home internet warning: Most residential ISPs limit upload to 10-50 Mbps (even with 500 Mbps download). Insufficient for 20+ player servers.
VPS/datacenter: 1 Gbps uplink standard (supports 500+ players bandwidth-wise).
Latency (Ping) Impact
| Latency | Player Experience | Suitable For |
|---|---|---|
| 0-30ms | Perfect, instant response | PvP, parkour, minigames |
| 30-60ms | Good, slight delay | SMP, creative, survival |
| 60-100ms | Noticeable lag | Casual play only |
| 100ms+ | Frustrating lag | Unplayable for PvP |
Server location matters: Amsterdam/Netherlands hosting = 5-30ms for 70% of Europe.
