It's because it comes with a decent iGPU, not because of the NPU inside of that. The NPU portion is still the standard tiny 50 TOPS and could be filled with normal RAM bandwidth like on a much cheaper machine.

On the RAM bandwidth side it depends if you want to look at it as "glass is half full" or "glass is half empty". For "glass is half full" the GPU has access to a ton of RAM at ~2x-4x the bandwidth of normal system memory an iGPU would have and so you can load really big models. For "glass is half empty" that GPU memory bandwidth is still nearly 2x less than a even a 5060 dGPU (which doesn't have to share any of that bandwidth with the rest of the system), but you won't fit as large of a model on a dGPU and it won't be as power efficient.

Speaking of power efficiency - it is decently power efficient... but I wouldn't run AI on battery on mine unless I was plugged in anyways as it still eats through the battery pretty quick when doing so. Great general workstation laptop for the size and wattage though.
