Can the RTX 3090 run NVIDIA Nemotron 3 Nano 4B?
Yes. NVIDIA Nemotron 3 Nano 4B fits the RTX 3090's 24 GB at Q4_K_M (about 3.8 GB needed), running at an estimated 274 tok/s. There's room for up to FP16 if you want higher quality.

| Quant | Weights | Needs | Fit | Est. speed |
|---|---|---|---|---|
| Q4_K_M | 2 GB | 3.8 GB | Fits easily | ~274 tok/s |
| Q5_K_M | 3 GB | 4.8 GB | Fits easily | ~183 tok/s |
| Q8_0 | 4 GB | 5.8 GB | Fits easily | ~137 tok/s |
| FP16 | 8 GB | 9.8 GB | Fits easily | ~68 tok/s |
Estimates. Needs = weights + 1.8 GB for KV cache and runtime at modest context. Speed is single-stream decode scaled from the RTX 3090's 936 GB/s bandwidth (XiongjieDai/GPU-Benchmarks-on-LLM-Inference). Long contexts need more memory and run slower.

Frequently asked
Quick answers
Can the NVIDIA RTX 3090 run NVIDIA Nemotron 3 Nano 4B?
Yes. NVIDIA Nemotron 3 Nano 4B fits the RTX 3090's 24 GB at Q4_K_M (about 3.8 GB needed), running at an estimated 274 tok/s. There's room for up to FP16 if you want higher quality.
How much VRAM does NVIDIA Nemotron 3 Nano 4B need?
About 2 GB of weights at Q4_K_M, 4 GB at Q8_0 and 8 GB at FP16. Add roughly 1.8 GB for the KV cache and runtime at modest context lengths.
How fast is NVIDIA Nemotron 3 Nano 4B on the RTX 3090?
Roughly 274 tokens per second at Q4_K_M (single user, llama.cpp-style decode). This is an estimate from the RTX 3090's 936 GB/s memory bandwidth.
