Can the RTX 4000 Ada run Qwen3 30B-A3B?
No. Qwen3 30B-A3B needs about 21 GB and the RTX 4000 Ada has at most 20 GB of VRAM. Ollama can still start it by putting part of the model in system RAM, but it runs several times slower. The most capable model it runs well is gpt-oss 20B, at about 63 tok/s.

How we estimate
Speed is roughly memory bandwidth divided by the weights read per token, calibrated on our own rack. Sizes are Ollama's default 4-bit downloads plus about 1.2 GB for context. Real results are usually within about a third. Measured it yourself? Send us the number.
