AMD Radeon PRO W7900
The AMD Radeon PRO W7900 has 48GB of VRAM and 864 GB/s of memory bandwidth. Its sweet spot tops out around Qwen3.6-35B-A3B — the largest model that loads cleanly at a quality quant with llama.cpp at 8K context.
AMD verdicts are beta: fit is physics and holds, but ROCm/Vulkan speed tiers aren't calibrated yet — treat tiers as provisional until real measurements land.

AMD Radeon PRO W7900 for local AI — common questions
- How much VRAM does the AMD Radeon PRO W7900 have?
- The AMD Radeon PRO W7900 has 48GB of VRAM with 864 GB/s of memory bandwidth. VRAM sets which models fit; bandwidth sets how fast they feel once they do.
- Is the AMD Radeon PRO W7900 good for running AI models locally?
- Yes. 48GB is enough headroom for the large open models most people want to run locally. The largest model it loads cleanly is Qwen3.6-35B-A3B, at a quality quant with llama.cpp at 8K context.
- What runtimes work with the AMD Radeon PRO W7900?
- It runs on ROCm · Vulkan, which covers Ollama, llama.cpp and LM Studio. Runtime choice affects speed and features, not whether a model fits.
