StarCoder Minimum System Requirements: A Complete Setup Guide

StarCoder is a powerful AI model for code generation, trained on massive amounts of open-source code. It’s widely used by developers for auto-completing code, generating scripts, debugging and assisting in software development.

But before you start using StarCoder locally, there’s a big question: Does your machine have enough power to run it smoothly?

Unlike some lighter models, StarCoder requires a strong GPU, plenty of RAM, and fast storage to handle code generation efficiently. This guide breaks down the hardware and software requirements you’ll need to run StarCoder locally without slowdowns.

StarCoder comes in different variants, and the system requirements depend on the model size you’re using.

Component: CPU

• Minimum (Basic Model): 8-core (Intel i7/Ryzen 7)
• Recommended (Mid-Sized Model): 12-core (Intel i9/Ryzen 9)
• Optimal (Full Model - 15.5B Parameters): 16-core (Intel Xeon/Threadripper)

Component: GPU

• Minimum (Basic Model): RTX 3060 (12GB VRAM)
• Recommended (Mid-Sized Model): RTX 3090 (24GB VRAM)
• Optimal (Full Model - 15.5B Parameters): 2x A100 (40GB VRAM each)

Component: RAM

• Minimum (Basic Model): 16GB DDR4
• Recommended (Mid-Sized Model): 32GB DDR4
• Optimal (Full Model - 15.5B Parameters): 64GB+ DDR5

Component: Storage

• Minimum (Basic Model): 250GB SSD
• Recommended (Mid-Sized Model): 1TB SSD (NVMe)
• Optimal (Full Model - 15.5B Parameters): 2TB SSD (NVMe RAID)

Component: OS

• Minimum (Basic Model): Ubuntu 20.04+, Windows 10
• Recommended (Mid-Sized Model): Ubuntu 22.04+, Windows 11
• Optimal (Full Model - 15.5B Parameters): Custom Linux OS (for multi-GPU setups)

While StarCoder is optimized for GPU acceleration, your CPU still plays a role in managing workloads and data transfers. If you’re running the basic StarCoder model, an 8 core CPU (Intel i7/Ryzen 7) is enough. However, if you plan to run larger models, you’ll need at least a 12 core Intel i9 or Ryzen 9 processor to keep up with the computational demands.

RAM Considerations

• 16GB RAM: Works for smaller models, but you might face slowdowns with large codebases.
• 32GB RAM: Recommended for most users enough to generate code smoothly.
• 64GB+ RAM: Required for multi tasking, handling larger prompts or running StarCoder at full scale.

GPU: The Most Critical Component

Since StarCoder is optimized for GPUs, having the right graphics card will make a huge difference in how fast and efficiently it runs.

StarCoder Variant: Small Model (1B-5B params)

• Minimum GPU (VRAM Required): RTX 3060 (12GB VRAM)
• Recommended GPU: RTX 3090 (24GB VRAM)
• Optimal Multi-GPU Setup: 2x RTX 4090 (48GB VRAM total)

StarCoder Variant: Mid-Sized Model (7B-10B params)

• Minimum GPU (VRAM Required): RTX 3090 (24GB VRAM)
• Recommended GPU: RTX 4090 (24GB VRAM)
• Optimal Multi-GPU Setup: 2x A100 (40GB VRAM each)

StarCoder Variant: Full Model (15B+ params)

• Minimum GPU (VRAM Required): 1x A100 (40GB VRAM)
• Recommended GPU: 2x A100 (80GB VRAM total)
• Optimal Multi-GPU Setup: 4x H100 (Enterprise-level)

• Recommended GPU: 2x A100 (80GB VRAM total)
• Optimal Multi-GPU Setup: 4x H100 (Enterprise-level)

The larger the model, the more VRAM you need. Running StarCoder’s full version (15B+ parameters) requires at least 40GB VRAM, meaning you’ll need an A100 GPU or a multi GPU setup.

If you only have a consumer GPU (RTX 3060/3090), consider running a smaller quantized version of StarCoder.

StarCoder’s model weights and cache files take up significant storage space, so a fast SSD (preferably NVMe) is crucial.

Storage Requirement & Recommended Disk Type:

• Basic Model (1B-5B parameters): 250GB SSD (SATA or NVMe)
• Mid-Sized Model (7B-10B parameters): 500GB SSD (NVMe)
• Full Model (15B+ parameters): 1TB+ SSD (NVMe or RAID setup)

Why SSDs? Loading large models from HDDs is painfully slow. NVMe SSDs significantly reduce model load times and improve inference speeds.

To run StarCoder, you’ll need to install some essential software and dependencies. Software & Required Versions:

• Python: 3.8+ (Python 3.10 recommended)
• CUDA (for NVIDIA GPUs): 11.2+
• PyTorch: 1.10+ (for GPU acceleration)
• Hugging Face Transformers: Latest version
• Git & Wget: Required for downloading model files

Wondering how fast StarCoder will run on your setup? Here’s what you can expect based on your GPU power. Task Performance Across GPUs:

• Small Code Snippets:

  • RTX 3060 (12GB VRAM): 5-10 sec response time
  • RTX 3090 (24GB VRAM): <3 sec response time
  • A100 (40GB VRAM): <1 sec response time

• Medium-Sized Code Blocks:

  • RTX 3060 (12GB VRAM): 15-20 sec
  • RTX 3090 (24GB VRAM): 5-7 sec
  • A100 (40GB VRAM): <2 sec

• Large Codebases & Debugging:

  • RTX 3060 (12GB VRAM): Slow (Not Recommended)
  • RTX 3090 (24GB VRAM): Usable (~10 sec per response)
  • A100 (40GB VRAM): Fast & Efficient

What This Means:

• If you’re working with short snippets or simple code, a RTX 3060 will work fine.

• For large-scale projects or real time inference, you’ll need a powerful GPU (RTX 3090, A100 or multi-GPU setup).
