Can AMD Radeon PRO W7900 run Mistral 7B?

7B parameter LLM model on 48GB GDDR6 ECC

Yes — runs at full precision
~24-29 tok/sUsable
SpeedFastest possible inference
QualityMaximum quality, no degradation
AMD GPUs lack CUDA. While Mistral 7B can technically run via llama.cpp/GGUF, the setup is more complex and less optimized than on NVIDIA hardware.

VRAM Requirements

Mistral 7B is a 7B parameter model. At full precision (FP16), it requires 14GB of VRAM. Your AMD Radeon PRO W7900 has 48GB — enough to run it without any quantization.

Maximum quality, no quantization

Q8 (8-bit)7GB (41GB free)

Near-lossless, ~50% size reduction

Q4 (4-bit)4.5GB (44GB free)

Good quality, ~75% size reduction

Your GPU VRAM: 48GB GDDR6 ECC at 864 GB/s bandwidth
Recommended system RAM: 96GB DDR5 (2x GPU VRAM minimum for model overflow)

What This Means in Practice

With AMD Radeon PRO W7900 running Mistral 7B at full precision, you get the highest quality responses with no quantization artifacts. This is ideal for tasks requiring nuanced reasoning, creative writing, and complex analysis. You'll have the best possible experience with this model.

How to Set It Up

Step 1: Install Ollama

curl -fsSL https://ollama.com/install.sh | sh

Ollama is the easiest way to run local LLMs. Works on Linux, macOS, and Windows.

Step 2: Download and run Mistral 7B

ollama run mistral:7b

This downloads the model (~14GB). First run takes a few minutes.

Step 3: Verify GPU is being used

rocm-smi

Check that VRAM usage increases when the model loads. You should see ~14GB used.
