Can RX 7700 XT 12GB run Nemotron-3-Nano-Omni-30B-A3B-Reasoning-BF16?

AMD · 12 GB GDDR6 · 432 GB/s bandwidth · NVIDIA · 30.0B (active 3.0B) · MoE · model ctx up to 256K

No — Nemotron-3-Nano-Omni-30B-A3B-Reasoning-BF16 at Q4 needs ≈ 17.8 GB even at 4K context, beyond the RX 7700 XT 12GB's 12 GB GDDR6. It would only run with heavy CPU/disk offload. Decode at Q4/8K: ≈ 115.1 tok/s (estimated, batch 1). FP16 needs ≈ 61.6 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	17.8 GB	No	119.0 est.
Q4	8K default	18.1 GB	No	115.1 est.
Q4	32K	19.9 GB	No	95.2 est.
FP16	4K	61.3 GB	No	—
FP16	8K default	61.6 GB	No	—
FP16	32K	63.4 GB	No	—

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).
