Frequently Asked Questions
- How much VRAM does Qwen2.5 Coder 32B need?
Qwen2.5 Coder 32B requires 20.5 GB of VRAM at Q4_K_M, or 33.6 GB at Q8_0. Full 33K context adds up to 8.1 GB (28.6 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 32.8B × 4.8 bits ÷ 8 = 19.7 GB
KV Cache + Overhead ≈ 0.8 GB (at 2K context + ~0.3 GB framework)
KV Cache + Overhead ≈ 8.9 GB (at full 33K context)
VRAM usage by quantization
Q4_K_M20.5 GBQ4_K_M + full context28.6 GB- Can NVIDIA GeForce RTX 4090 run Qwen2.5 Coder 32B?
Yes, at Q5_K_S (23.4 GB) or lower. Higher quantizations like Q5_K_M (24.2 GB) exceed the NVIDIA GeForce RTX 4090's 24 GB.
- What's the best quantization for Qwen2.5 Coder 32B?
For Qwen2.5 Coder 32B, Q4_K_M (20.5 GB) offers the best balance of quality and VRAM usage. Q4_K_L (20.9 GB) provides better quality if you have the VRAM. The smallest option is IQ2_XXS at 9.8 GB.

- Can I run Qwen2.5 Coder 32B on a Mac?
Qwen2.5 Coder 32B requires at least 9.8 GB at IQ2_XXS, which exceeds the unified memory of most consumer Macs. You would need a Mac Studio or Mac Pro with a high-memory configuration.
- Can I run Qwen2.5 Coder 32B locally?
Yes — Qwen2.5 Coder 32B can run locally on consumer hardware. At Q4_K_M quantization it needs 20.5 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.
- How fast is Qwen2.5 Coder 32B?
At Q4_K_M, Qwen2.5 Coder 32B can reach ~142 tok/s on AMD Instinct MI300X. On NVIDIA GeForce RTX 4090: ~32 tok/s. Speed depends mainly on GPU memory bandwidth. Real-world results typically within ±20%.
tok/s = (bandwidth GB/s ÷ model GB) × efficiency
Example: AMD Instinct MI300X → 5300 ÷ 20.5 × 0.55 = ~142 tok/s
Estimated speed at Q4_K_M (20.5 GB)
~142 tok/s~32 tok/s~106 tok/s~88 tok/sReal-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
- What's the download size of Qwen2.5 Coder 32B?
At Q4_K_M, the download is about 19.66 GB. The full-precision Q8_0 version is 32.76 GB. The smallest option (IQ2_XXS) is 9.01 GB.
- Which GPUs can run Qwen2.5 Coder 32B?
