Can MI300X 192GB run Qwen3-Coder-Next?

AMD · 192 GB HBM3 · 5300 GB/s bandwidth · Alibaba · 79.7B (active 3B) · MoE · model ctx up to 256K

Yes — the MI300X 192GB (192 GB HBM3) 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 192 GB. Decode at Q4/8K: ≈ 1124.2 tok/s (estimated, batch 1). FP16 (≈ 161.0 GB) also fits, at ≈ 309.2 tok/s (estimated). 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	1124.2 est.
Q4	8K default	45.44 GB	Yes	1124.2 est.
Q4	32K	47.24 GB	Yes	1124.2 est.
FP16	4K	160.7 GB	Yes	309.2 est.
FP16	8K default	161.0 GB	Yes	309.2 est.
FP16	32K	162.8 GB	Yes	309.2 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).
