Frequently asked questions

Can the RTX 4060 Ti 8 GB run Qwen3 8B?
The model needs about 6.9 GB and fits in the 7.7 GB available (0.7 GB left).
Which quantization should I use on the RTX 4060 Ti 8 GB?
Q4_K_M is the highest-precision quantization that fits entirely in VRAM at 8K context. ~6.9 GB / 7.7 GB.
What is the largest context on the RTX 4060 Ti 8 GB?
At Q4_K_M, about 12K tokens fit entirely in VRAM with an f16 KV cache. A q8_0 KV cache roughly doubles that.
How fast is Qwen3 8B (RTX 4060 Ti 8 GB)?
We estimate 36–49 tok/s (estimate, confidence low). Based on: memory bandwidth (288 GB/s) and model size.
