Qwen3 hits VRAM wall on RTX 5000 Ada

The RTX 5000 Ada laptop is being choked by its 16GB VRAM and mobile power limits, making flagship models like Qwen3 235B functionally unusable for real-time tasks. Results showing 13 t/s on a 4B model suggest power-steering or software bottlenecks, while the 1.5 t/s on the 235B model confirms a memory wall hit as weights overflow into system RAM. Despite Qwen3’s MoE architecture designed for efficiency, high-bandwidth memory remains a prerequisite that current laptop GPUs lack, making 32GB+ VRAM the necessary baseline for professional local inference.
