Want it faster?
Speed comes from memory bandwidth: the card reads all 5.2 GB of active weights for every token. On the GTX 1080, Qwen3 4B runs at about 70 tok/s if you can trade some quality for speed. Cards that run Qwen3 8B faster:
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.
