Actually it is neither of those. It's a technology comparison between the newest nVidia graphics card and the ATi HD series graphics cards, in which nVidia features a lot more things that the HD series don't. I don't know which features, though, since I don't speak korean/chinese/japanese, but I can guess:
DX11 features, SLI/crossfire, 3D gaming, mobile (for laptops and such) version, GPU calculated physics (physx), etc.
