Can AMD Radeon PRO W7900 run Qwen 2.5 32B?
32B parameter LLM model on 48GB GDDR6 ECC
VRAM Requirements
Qwen 2.5 32B is a 32B parameter model. At full precision (FP16), it requires 64GB of VRAM. Your AMD Radeon PRO W7900 has 48GB, so you'll need to quantize it to 8-bit (Q8) to fit.
Maximum quality, no quantization
Near-lossless, ~50% size reduction
Good quality, ~75% size reduction
Recommended system RAM: 96GB DDR5 (2x GPU VRAM minimum for model overflow)
What This Means in Practice
Running Qwen 2.5 32B at 8-bit quantization on AMD Radeon PRO W7900 gives you virtually identical quality to full precision while using roughly half the VRAM. Most users cannot distinguish Q8 output from FP16. This is the recommended precision for daily use — it's the best balance of quality and resource usage.
How to Set It Up
Step 1: Install Ollama
curl -fsSL https://ollama.com/install.sh | shOllama is the easiest way to run local LLMs. Works on Linux, macOS, and Windows.
