Radeon PRO W7900 Runs 70B Models at Full Precision
The Radeon PRO W7900 workstation GPU demonstrates capability to run 70 billion parameter AI models at full precision, offering professionals a powerful
Someone got a Radeon PRO W7900 running local AI models and the unified memory setup makes a huge difference for LLMs.
Real-world performance:
- DeepSeek 70B at 12 tokens/sec (full precision, no quantization)
- ComfyUI with LTX2 averaging 12 seconds per iteration
- Can allocate 96GB+ directly to GPU without PCIe bandwidth limits
The main advantage is skipping quantization completely - no quality loss from compressed models. Full weights just fit in memory and run.
For setup instructions and ComfyUI nodes optimized for AMD cards, there’s a walkthrough repo at: https://github.com/bkpaine1
Pretty solid option for running bigger models locally without dealing with 4-bit or 8-bit quants.
