DeepSeek Coder V2 33B needs 19.5 GB VRAM at Q4. The RTX 5090 32GB has 32 GB.
🔍 DeepSeek Coder V2 33B (DeepSeek) is a 33B-parameter model for code generation and analysis. Top-tier code model, competitive with GPT-4 for programming. The question is whether the RTX 5090 32GB’s 32 GB of VRAM can hold it — here’s the exact math.
VRAM requirements
| Quantization | VRAM needed | RTX 5090 32GB |
|---|---|---|
| Q4_K_M (recommended) | 19.5 GB | ✅ |
| Q8_0 (near-lossless) | 34 GB | ❌ |
Expected performance
Running DeepSeek Coder V2 33B at Q4 on the RTX 5090 32GB, expect roughly ~31 tokens/sec in Ollama or llama.cpp — comfortably faster than reading speed, so chat feels responsive.
Headroom: 19.5 GB used of 32 GB leaves about 12.5 GB free for KV cache (context). That’s fine for 4-8K context; for 32K+ you may need a smaller batch or a lower quant.
