How they compare
Qwen 3 30B-A3B comes from Alibaba and Qwen 3.6 27B from Alibaba. 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.
At 30B vs 27B parameters, Qwen 3 30B-A3B is the larger of the two. At Q4, Qwen 3.6 27B fits in about 16 GB of VRAM versus 19 GB for the other — a 3 GB difference that matters on consumer GPUs.
The two models target different sweet spots: Qwen 3 30B-A3B is tuned for chat, general, reasoning, multilingual, moe, while Qwen 3.6 27B leans toward chat, general, code, reasoning, vision, multilingual. Match the model to your dominant workload rather than to raw size.
On a typical mid-range GPU, Qwen 3 30B-A3B pushes roughly 40 tokens/sec versus 13, so it is the more responsive choice for interactive or high-volume use. For long-context work, Qwen 3.6 27B offers the bigger window (256k vs 128k tokens).
Memory, quantization & throughput
Across quantization levels, Qwen 3 30B-A3B requires Q4 ≈ 19 GB, Q5 ≈ 23 GB, Q8 ≈ 35 GB, FP16 ≈ 62 GB, while Qwen 3.6 27B requires Q4 ≈ 16 GB, Q5 ≈ 19 GB, Q8 ≈ 29 GB, FP16 ≈ 54 GB. In practice Qwen 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, Qwen 3 30B-A3B needs roughly 32 GB of system RAM to run on CPU and Qwen 3.6 27B about 28 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 Qwen 3 30B-A3B and 13 from Qwen 3.6 27B, scaling up to 100 and 32 tokens/sec on high-end hardware.
Which fits your GPU
