How they compare
Nemotron Nano 3 30B-A3B comes from NVIDIA and Qwen 3 30B-A3B from Alibaba, they belong to the Nemotron and Qwen families respectively. This comparison is built entirely from structured specs — parameter count, VRAM by quantization, context window, license, and published benchmark scores — so the verdict below reflects measurable differences rather than marketing claims.
Nemotron Nano 3 30B-A3B and Qwen 3 30B-A3B share the same 30B parameter class. Both need about 19 GB of VRAM at a Q4 quantization, so they fit the same GPU tier.
The two models target different sweet spots: Nemotron Nano 3 30B-A3B is tuned for chat, general, reasoning, moe, while Qwen 3 30B-A3B leans toward chat, general, reasoning, multilingual, moe. Match the model to your dominant workload rather than to raw size.
For long-context work, Nemotron Nano 3 30B-A3B offers the bigger window (976k vs 128k tokens).
Memory, quantization & throughput
Across quantization levels, Nemotron Nano 3 30B-A3B requires Q4 ≈ 19 GB, Q5 ≈ 23 GB, Q8 ≈ 35 GB, FP16 ≈ 62 GB, while Qwen 3 30B-A3B requires Q4 ≈ 19 GB, Q5 ≈ 23 GB, Q8 ≈ 35 GB, FP16 ≈ 62 GB. In practice Nemotron Nano 3 30B-A3B wants a 24 GB card at Q4, so plan your GPU around the Q4 or Q5 figure unless you specifically need the higher fidelity of Q8 or FP16.
Without a GPU, Nemotron Nano 3 30B-A3B needs roughly 32 GB of system RAM to run on CPU and Qwen 3 30B-A3B about 32 GB — workable for offline use but far slower than GPU inference. On a mid-range GPU you can expect on the order of 40 tokens/sec from Nemotron Nano 3 30B-A3B and 40 from Qwen 3 30B-A3B, scaling up to 100 and 100 tokens/sec on high-end hardware.
