What GPU do I need to run nvidia/NVIDIA-Nemotron-3-Super-120B-A12B-BF16?
123.6B parameters, published in BF16. View on Hugging Face
Set up NVIDIA-Nemo…r-120B-A12B-BF16NVIDIA-Nemotron-3-Super-120B-A12B-BF16 is published by nvidia on Hugging Face, with 1,056,440 downloads and 423 likes to date. It's a NemotronHForCausalLM model built for text-generation, published natively in BF16.
VRAM required & cheapest live GPU fit
Required VRAM = weight size at each precision, plus a fixed overhead for KV-cache, activations, and fragmentation. Full formula and assumptions: methodology.
A GPU is only matched to a row if its hardware supports that precision, and the primary recommendation is always a single-GPU fit when one exists.
INT4 requires a quantized checkpoint actually published for this model, check its Hugging Face page before relying on this row.
Cheapest way to run NVIDIA-Nemotron-3-Super-120B-A12B-BF16 at its published (BF16) precision: 6× RTX A6000 on runpod, at $0.330/hr per GPU ($1.98/hr total). Quantizing to FP8 or INT4 (rows above) can cost less, but requires a compatible quantized checkpoint to exist for this model.
NVIDIA-Nemotron-3-Super-120B-A12B-BF16: common questions
Can NVIDIA-Nemotron-3-Super-120B-A12B-BF16 run on a single GPU?
No. At BF16 it needs 276.3 GB of VRAM, more than a single 32 GB desktop card holds. The cheapest capable card in the live feed is a 48.0 GB RTX A6000, and it takes 6 of them.
How many GPUs do I need to run NVIDIA-Nemotron-3-Super-120B-A12B-BF16?
6 at BF16. It needs 276.3 GB of VRAM and the cheapest capable live offer is a 48.0 GB RTX A6000 on runpod, so 6 of them come to $1.98/hr in total.
Does quantizing NVIDIA-Nemotron-3-Super-120B-A12B-BF16 lower the GPU bill?
Yes. At BF16 the cheapest live fit is 6 RTX A6000 cards on runpod at $1.98/hr. At INT4 (quantized) it drops to one RTX PRO 6000 on simplepod at $1.00/hr, provided a quantized checkpoint exists for it.
