Can RTX 3090 Ti 24GB run NVIDIA-Nemotron-3-Super-120B-A12B-BF16?

NVIDIA · 24 GB GDDR6X · 1008 GB/s bandwidth · NVIDIA · 120.0B (active 12.0B) · MoE · model ctx up to 256K

No — NVIDIA-Nemotron-3-Super-120B-A12B-BF16 at Q4 needs ≈ 68.2 GB even at 4K context, beyond the RTX 3090 Ti 24GB's 24 GB GDDR6X. It would only run with heavy CPU/disk offload. Decode at Q4/8K: ≈ 18.3 tok/s (estimated, batch 1). FP16 needs ≈ 243.4 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	68.2 GB	No	18.9 est.
Q4	8K default	69.4 GB	No	18.3 est.
Q4	32K	76.6 GB	No	15.0 est.
FP16	4K	242.2 GB	No	—
FP16	8K default	243.4 GB	No	—
FP16	32K	250.6 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).
