NVIDIA GeForce RTX 4080 Laptop GPU for local LLMs
Written by Jakub Rusinowski · Last updated
With 12 GB of GDDR6 at 432 GB/s, the RTX 4080 Laptop GPU runs 76 catalogued models at Q4_K_M with 8K context. The largest that fits is Qwen 3 14B (~11.1 GB), and the top pick is Cosmos 3 Nano at 38–73 tok/s.
12 GB of GDDR6 on a 192-bit bus, 432 GB/s. Not the 16 GB desktop RTX 4080. Power depends on the chassis and is not stored.

Frequently asked questions
Can the NVIDIA GeForce RTX 4080 Laptop GPU run local LLMs?
Yes. With 12 GB (12 GB usable by a model) it runs 76 of the catalogued models at Q4_K_M with 8K context; the largest is Qwen 3 14B, needing about 11.1 GB.
How fast is the NVIDIA GeForce RTX 4080 Laptop GPU for AI inference?
It is estimated to run Llama 3.1 8B at 44–84 tok/s at Q4_K_M. Llama 3.3 70B does not fit: it needs about 44 GB against 12 GB usable. These are modelled estimates from memory bandwidth, not measurements; the methodology page shows the formula.
What LLMs can I run on 12 GB?
Among the best that fit: Cosmos 3 Nano, Ministral 3 14B, DeepSeek R1 Distill Qwen 14B, Mellum2.1 12B Thinking, Gemma 4 12B (Unified).
