First of all 720p * 9 = 4k.
Second of all that only has regard for rendering the exact pixels, there are more things that decides what it can render. For example we don't know how much gpgpu compute it can do, we don't know how much ram bandwith it will have, we don't know what types of bottlenecks it could have in general.
It really is too early to call.
