Want it faster?
Speed comes from memory bandwidth: the card reads all 9.3 GB of active weights for every token. On the RTX 4080, gpt-oss 20B runs at about 130 tok/s if you can trade some quality for speed. Cards that run Qwen3 14B 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.
