Can RX 7800 XT 16GB run Qwen3-8B?

AMD · 16 GB GDDR6 · 624 GB/s bandwidth · Alibaba · 8.2B · model ctx up to 128K

Fit & speed by quant and context

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).
