What the Qwen3-14B numbers mean
The fastest verified result on our board is 90.8 output tok/s on an RTX PRO 6000 Blackwell at FP8 with a 32768-token context. That is about 11.0 ms per generated token — 500 tokens takes roughly 5.5 seconds. Across the 3 records we hold for this model the range is 35.8–90.8 tok/s on 3 GPUs, because quantisation, context length and the engine build all move the number.
How much VRAM does Qwen3-14B need?
Qwen3-14B has 14.0B parameters. These estimates use the same formula as the VRAM calculator: weights, plus about 15% for a moderate-context KV cache and runtime overhead, plus a small engine floor.
| Quantisation | Estimated VRAM | Smallest card that fits |
|---|---|---|
| Q4_K_M (4-bit) | 9.9 GB | 12 GB |
| Q8_0 (8-bit) | 17.9 GB | 24 GB |
| FP16 (16-bit) | 33.0 GB | 48 GB |
