|||Just look at a laptop and a new high end desktop graphics card together...you will note the video card is bigger than the laptop!!! other than physical size, and in an effort to keep the overall size and weight of the laptop down, "built in" graphics are used. To make a laptop perform as well as a high end desktop (which can and is done) the expense is exorbitant at best! A laptops primary purpose is work related so the need for hi end graphics isn't there. Since the CPU and video are soldered onto the mother board and getting at a laptop mother board is so difficult and tricky..to "upgrade" almost anything outside the RAM and hard drive its simpler to just buy a new/better equipped laptop.|||Because it's attached, like your arm's attached to your torso.
To replace your arm, I'll have to cut off your original arm, keep all the connections intact, so I can attach a new arm with all the other connections, but then I'll still have to match all the other sizes and connections like nerves and muscles and blood vessels and tendons and whatnot.
Same in a laptop: the video module is a part of the mainboard, and you can't cut a mainboard: the connections are INSIDE the board (in multiple layers).
Desktops are different. The video card goes in an expansion slot, just remove and replace. Plenty of room inside to do the work. It's like you've already been bionic-ized and just unplug the old arm and put in an new one.
