What the Qwen3-1.7B numbers mean
The fastest verified result on our board is 198.1 output tok/s on an RTX 3060 x2 at Q4_K_M with a 512-token context. That is about 5.0 ms per generated token — 500 tokens takes roughly 2.5 seconds. Prompt processing on the same record runs at 7121.2 tok/s, so a 2,000-token prompt is read in about 0.3 seconds. Peak VRAM was measured at 6.7 GB.
How much VRAM does Qwen3-1.7B need?
Qwen3-1.7B has 2.0B 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) | 2.1 GB | 8 GB |
| Q8_0 (8-bit) | 3.2 GB | 8 GB |
| FP16 (16-bit) | 5.4 GB | 8 GB |
