so i have beeen wondering for a while, i have see nnvidia having graphics cards, with (for example) the name GTX 780, for desktops, and GTX780M for laptops.

now, im wondering, do they perform the same, because, the same number would imply so, but on the other side, the desktop GPU is way bigger. so, is the desktop version superiour?
 
And why would you even be asking? Laptop cards are for laptops, desktop cards are for desktops. The question of choosing a laptop PC instead of a desktop PC is more about what you'll be using it for (i.e. PC will stay in the same place 24/7, vs. a PC you want to take to class) rather than which has better graphics (although desktop will usually beat laptop any day).
