DeepSeek Coder V2 33B needs 19.5 GB VRAM at Q4. The Radeon RX 7900 XTX 24GB has 24 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 Radeon RX 7900 XTX 24GB’s 24 GB of VRAM can hold it — here’s the exact math.
VRAM requirements
| Quantization | VRAM needed | Radeon RX 7900 XTX 24GB |
|---|---|---|
| Q4_K_M (recommended) | 19.5 GB | ✅ |
| Q8_0 (near-lossless) | 34 GB | ❌ |
Expected performance
Running DeepSeek Coder V2 33B at Q4 on the Radeon RX 7900 XTX 24GB, expect roughly ~19 tokens/sec in Ollama or llama.cpp — comfortably faster than reading speed, so chat feels responsive.
Headroom: 19.5 GB used of 24 GB leaves about 4.5 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.

Frequently asked questions
Can the Radeon RX 7900 XTX 24GB run DeepSeek Coder V2 33B?
Yes — runs great at Q4 (recommended). DeepSeek Coder V2 33B needs 19.5 GB VRAM at Q4_K_M; the Radeon RX 7900 XTX 24GB has 24 GB.
How much VRAM does DeepSeek Coder V2 33B need?
DeepSeek Coder V2 33B needs about 19.5 GB at Q4_K_M (recommended) and 34 GB at Q8_0.
How many tokens per second will the Radeon RX 7900 XTX 24GB get on DeepSeek Coder V2 33B?
Roughly ~19 tokens/sec at Q4 in Ollama or llama.cpp.
About the speed figure. The tokens/sec number above is an estimate, not a measured benchmark. Real throughput depends on your runtime and backend (Ollama, llama.cpp, vLLM), the exact quantization you download, context length, memory bandwidth, and whether any layers are offloaded to CPU. Treat it as a rough guide to the tier of performance, not a promised result.
