RTX 3080 Laptop GPU 16GB strengths and weaknesses

Strengths

  • Runs 35B MoE models: Qwen3.6 35B A3B at 108 tok/s in 15.7 GB
  • Low power draw: 150 W board power; a 300 W PSU is enough

Weaknesses

  • 70B models don't fit: Llama 3.3 70B Instruct needs 51.3 GB at Q4 vs 16 GB here
  • No FP8 or NVFP4: Ampere predates both; use GGUF, AWQ or GPTQ builds

RTX 3080 Laptop GPU 16GB FAQ

What is the largest model the RTX 3080 Laptop GPU 16GB can run?

Gemma 4 26B A4B IT (25.8B) is the largest at 4-bit or better: at Q4_K_S it uses 15.5 GB of 16 GB, and runs at about 95.1 tok/s. At 3-bit, a bigger model fits too: Gemma 2 27B IT (27.2B) at IQ3_M, 15.0 GB.

Can the RTX 3080 Laptop GPU 16GB run Qwen3.5 9B?

Yes. Qwen3.5 9B fits at Q4_K_M, using 6.6 GB of 16 GB, and it is the best model that runs well on this card.

Can the RTX 3080 Laptop GPU 16GB run 70B models?

No. Llama 3.3 70B Instruct needs 51.3 GB at Q4, more than the 16 GB on this card.

How many tokens per second does the RTX 3080 Laptop GPU 16GB give?

About 45.8 tok/s on Qwen3.5 9B at Q4_K_M, with the first token after 4.2 s on a 4K-token prompt.

What power supply does the RTX 3080 Laptop GPU 16GB need?

Plan a 300 W PSU (2× the 150 W TDP).

Is 16 GB enough for coding and agents?

Yes for coding: GPT OSS 20B, the best of the 2 coding models that fit, runs at about 98 tok/s. For agents, not yet: no agent-scored model fits in less than 96 GB.

Is renting cheaper than buying an RTX 3080 Laptop GPU 16GB?

An RTX 3090 (24 GB) rents from $0.18/hr. With regular daily use, owning pays off.
