This setup is broadly balanced for this model.
Very little memory headroom
You can run the model, but there is not much room left for longer context, bigger batches, extra apps, or future model updates.
Buy headroom, not only minimum fit
A slightly larger memory tier gives you safer context growth and makes the recommendation more future-proof.

Yes, RTX 5080 Laptop 16GB can run Qwen 3 30B A3B at Q2_K quantization (Runs with offload (needs ~0.1 GB host RAM)). The recommended Q4_K_M requires 22.9 GB which exceeds available memory, but at Q2_K it needs only 16.2 GB. Expected decode speed: 95.3 tok/s.
Qwen 3 30B A3B (30.5B parameters) requires approximately 22.9 GB at Q4_K_M quantization. On RTX 5080 Laptop 16GB, it fits at Q2_K using 16.2 GB.
The recommended quantization is Q4_K_M, but on RTX 5080 Laptop 16GB the best fitting quantization is Q2_K, which uses 16.2 GB.
On RTX 5080 Laptop 16GB, Qwen 3 30B A3B achieves approximately 95.3 tokens per second decode speed with a time-to-first-token of 2032ms using Q2_K quantization.
For coding workloads, Qwen 3 30B A3B on RTX 5080 Laptop 16GB receives a F grade with 34.5 tok/s and 4K context.
On RTX 5080 Laptop 16GB, Qwen 3 30B A3B can safely use up to 14K tokens of context at Q2_K quantization. The model's official context limit is 131K, but available memory constrains the safe maximum.
Buy headroom, not only minimum fit. A slightly larger memory tier gives you safer context growth and makes the recommendation more future-proof.
