Why the hell do high end laptop gpus have 4gb vram?

Go to xoticpc, sager, go to the last model and scroll down to gpu...2 4096mb 780ms in SLI. They only game at 1080p....so why?

I've wondered this myself and the only answer I've been able to come up with is more ram=more ram modules=more heat dissipation. That seems like too simplistic an explanation though so I doubt it's right.

Epic basement pwn. Nobody needs portability if they want to game.

If we're going to get serious here, SLI 780ms is more powerful than what most of us have in our desktops. One 780m? Maybe not. But SLI? Yeah. It's a heavily overclocked 780 in your lap. When you need to have the portability, it's there, and the 1080p isn't going to phase those GPUs. But get a good laptop cooling mat to disspate the heat, and when you don't need the portability, these things will play at 1440 or 1600p pretty damn well.

VRAM is still RAM, GDDR5 is just DDR3 set up in a special way and some (low end) video cards just use DDR3 anyway. If you look at the back of your card you can see where each RAM module is mounted unless you have a backplate like I do. The actual ram should be covered up by your heatsink though since they need cooling as well. In every card that I've compared the different versions of they don't use larger capacity modules, they just use more of them. That may not be true for every card though.

As for the 780m, it's an underclocked 680/770 (underclocked to about 660ti/760 performance), not a 780. It's a full GK104 chip, not 110.

playing re6 with 8x sparse grid ss with 32xs(2x2 ss + 8 ms)+ mixed sample x128 + 32 forced anisotropic then I hear ps4 is powerful than my pc
