Nemotron 3 Nano 30B A3B GGUF — Hardware Requirements & GPU Compatibility

Chat

This is a GGUF-quantized version of NVIDIA's Nemotron 3 Nano 30B A3B, repackaged by Unsloth. Nemotron 3 Nano is NVIDIA's efficient language model using a Mixture-of-Experts (MoE) architecture with 30 billion total parameters and approximately 3 billion active parameters per token, designed to deliver strong performance with minimal computational overhead. The sparse MoE design makes this model far more efficient than its total parameter count suggests, requiring VRAM closer to a dense 3B model while producing output quality that competes with much larger architectures. Unsloth's GGUF conversion enables compatibility with llama.cpp and popular local inference frontends, making it an appealing option for users who want high-quality local inference without the hardware demands of a full 30B dense model.

How fast is Nemotron 3 Nano 30B A3B GGUF?

At Q4_K_M, Nemotron 3 Nano 30B A3B GGUF can reach ~147 tok/s on AMD Instinct MI300X. On NVIDIA GeForce RTX 4090: ~33 tok/s. Speed depends mainly on GPU memory bandwidth. Real-world results typically within ±20%.

tok/s = (bandwidth GB/s ÷ model GB) × efficiency

Example: AMD Instinct MI300X5300 ÷ 19.8 × 0.55 = ~147 tok/s

Estimated speed at Q4_K_M (19.8 GB)

~147 tok/s
~33 tok/s
~110 tok/s
~91 tok/s

Real-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
