RTX A5000 Laptop GPU strengths and weaknesses
Strengths
- Runs 35B MoE models: Qwen3.6 35B A3B at 108 tok/s in 15.7 GB
- Reads long prompts fast: A 4K-token prompt on Qwen3.5 9B starts answering in 2.0 s
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
Output speed depends on memory bandwidth (448 GB/s). Grey rows need more than 16 GB.

RTX A5000 Laptop GPU FAQ
What is the largest model the RTX A5000 Laptop GPU 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 A5000 Laptop GPU 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 A5000 Laptop GPU 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 A5000 Laptop GPU give?
About 45.8 tok/s on Qwen3.5 9B at Q4_K_M, with the first token after 2.0 s on a 4K-token prompt.
What power supply does the RTX A5000 Laptop GPU need?
Plan a 350 W PSU (2× the 165 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.
