Can RX 7700 XT 12GB run NVIDIA-Nemotron-3-Nano-4B-BF16?

AMD · 12 GB GDDR6 · 432 GB/s bandwidth · NVIDIA · 4.0B · model ctx up to 256K

Yes — the RX 7700 XT 12GB (12 GB GDDR6) can run NVIDIA-Nemotron-3-Nano-4B-BF16. At Q4 with the default 8K context it needs ≈ 4.0 GB VRAM (weights 2.2 GB + KV cache 0.8 GB + 1 GB runtime overhead), which fits within 12 GB. Decode at Q4/8K: ≈ 68.7 tok/s (estimated, batch 1). FP16 (≈ 9.8 GB) also fits, at ≈ 18.9 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	3.6 GB	Yes	68.7 est.
Q4	8K default	4.0 GB	Yes	68.7 est.
Q4	32K	6.4 GB	Yes	68.7 est.
FP16	4K	9.4 GB	Yes	18.9 est.
FP16	8K default	9.8 GB	Yes	18.9 est.
FP16	32K	12.2 GB	No	52.2 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).
