Can AMD Radeon PRO W7900 run DeepSeek R1 70B?
70B parameter LLM model on 48GB GDDR6 ECC
VRAM Requirements
DeepSeek R1 70B is a 70B parameter model. At full precision (FP16), it requires 140GB of VRAM. Your AMD Radeon PRO W7900 has 48GB, so you'll need to quantize it to 4-bit (Q4) 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
At 4-bit quantization, DeepSeek R1 70B fits in AMD Radeon PRO W7900's 48GB VRAM but with some quality trade-offs. Complex reasoning tasks and nuanced writing may show slight degradation. For casual chat, code assistance, and general queries, Q4 is perfectly usable. For critical work, consider a GPU with more VRAM to run at Q8.
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.
Step 2: Download and run DeepSeek R1 70B
ollama run deepseek-r1:70b:q4_K_MThis downloads the Q4_K_M quantized version (~40GB). First run takes a few minutes to download.
Step 3: Verify GPU is being used
rocm-smiCheck that VRAM usage increases when the model loads. You should see ~40GB used.
