Can RTX A6000 48GB run Qwen3-Coder-Next?

NVIDIA · 48 GB GDDR6 · 768 GB/s bandwidth · Alibaba · 79.7B (active 3B) · MoE · model ctx up to 256K

Yes — the RTX A6000 48GB (48 GB GDDR6) can run Qwen3-Coder-Next. At Q4 with the default 8K context it needs ≈ 45.44 GB VRAM (weights 43.84 GB + KV cache 0.6 GB + 1 GB runtime overhead), which fits within 48 GB. Decode at Q4/8K: ≈ 162.9 tok/s (estimated, batch 1). FP16 needs ≈ 161.0 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. Methodology.

Fit & speed by quant and context

Quant	Context	VRAM needed	Fits?	tok/s (decode)
Q4	4K	45.14 GB	Yes	162.9 est.
Q4	8K default	45.44 GB	Yes	162.9 est.
Q4	32K	47.24 GB	No	480.6 est.
FP16	4K	160.7 GB	No	11.4 est.
FP16	8K default	161.0 GB	No	11.4 est.
FP16	32K	162.8 GB	No	11.1 est.

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).
