Question 1

Can I run Qwen3 0.6B on a NVIDIA GeForce GTX 1660 Super?

Accepted Answer

Yes — NVIDIA GeForce GTX 1660 Super runs Qwen3 0.6B fully on GPU at the FP16 quantization. Full GPU inference — 6 GB VRAM meets the 1.6 GB recommendation.

Question 2

What quantization of Qwen3 0.6B should I use on a NVIDIA GeForce GTX 1660 Super?

Accepted Answer

For 6 GB VRAM on the NVIDIA GeForce GTX 1660 Super, the FP16 variant is the best fit. Estimated ~280 tokens/sec on the FP16 quantization.

Question 3

How fast does Qwen3 0.6B run on NVIDIA GeForce GTX 1660 Super?

Accepted Answer

Roughly 280 tokens/sec for FP16. Real speed depends on context length, backend (Ollama, llama.cpp, LM Studio), and KV cache size.

Question 4

What if NVIDIA GeForce GTX 1660 Super is not enough for Qwen3 0.6B?

Accepted Answer

Try a smaller quantization variant or run on CPU + RAM with the trade-off of slower generation.
