RTX 4050 Laptop GPU FAQ

What is the largest model the RTX 4050 Laptop GPU can run?

Qwen2.5 7B Instruct (7.6B) is the largest at 4-bit or better: at Q4_K_M it uses 5.8 GB of 6 GB, and runs at about 25.0 tok/s. At 3-bit, a bigger model fits too: Gemma 2 9B IT (9.2B) at IQ3_M, 5.7 GB.

Can the RTX 4050 Laptop GPU run Qwen3.5 4B?

Yes. Qwen3.5 4B fits at Q4_K_M, using 3.4 GB of 6 GB, and it is the best model that runs well on this card.

Can the RTX 4050 Laptop GPU run 14B models?

No. Qwen3 14B needs 11.9 GB at Q4, more than the 6 GB on this card.

How many tokens per second does the RTX 4050 Laptop GPU give?

About 38.3 tok/s on Qwen3.5 4B at Q4_K_M, with the first token after 3.5 s on a 4K-token prompt.

What power supply does the RTX 4050 Laptop GPU need?

Plan a 250 W PSU (2× the 115 W TDP).

Is renting cheaper than buying an RTX 4050 Laptop GPU?

An RTX 3080 Ti (12 GB) rents from $0.13/hr. With regular daily use, owning pays off.
