What it does well
The RTX 5070 Laptop GPU is the mainstream mobile-AI part most gaming/creator laptops actually ship with. The newer 12GB variant (up from the launch 8GB) is the one to seek for local AI — that extra 4GB is the difference between being stuck at 7-8B and comfortably running 13-14B models at Q4 on the go, with full CUDA support for Ollama, llama.cpp, and ComfyUI. At ~100W mobile it's a reasonable balance of capability and battery.
Where it struggles
The 8GB original variant is VRAM-starved and best avoided for local AI — and because both ship under the same '5070 Laptop' name, you must check the specific config. 384 GB/s bandwidth and mobile power limits keep it well behind the 5090 Mobile (24GB) for larger models, and like all gaming laptops, sustained inference means heat, fan noise, and throttling versus a desktop.
Bottom line
A solid mainstream laptop AI GPU if you get the 12GB version — capable of 13-14B local models with CUDA. Avoid the 8GB variant for serious local AI; step up to the 5090 Mobile if you need 24GB on a laptop.
