Can RX 7700 XT 12GB run Qwen3-Coder-480B-A35B-Instruct?
AMD · 12 GB GDDR6 · 432 GB/s bandwidth ·
Alibaba · 480.2B (active 35B) · MoE · model ctx up to 256K
No — Qwen3-Coder-480B-A35B-Instruct at Q4 needs ≈ 268.61 GB even at 4K context, beyond the RX 7700 XT 12GB's 12 GB GDDR6. It would only run with heavy CPU/disk offload. FP16 needs ≈ 968.4 GB — does not fit on this card. Estimates come from memory-bandwidth math; rows tagged measured override estimates. Relative ranking is more reliable than absolute tok/s.

Fits = weights + KV(ctx) + 1 GB overhead ≤ 95% of VRAM. Measured
anchors are context-agnostic; the fit verdict is recomputed per context. A missing tok/s
means the model is far beyond this card (offload-only territory).
