All laptops have "integrated" graphics by definition because the chip is soldered on to the motherboard. Before Intel started integrating graphics directly into CPU's, there was still a separate chip for graphics on the motherboard. This is what we now define as integrated and those "Intel HD" graphics are much, much better than they used to be.

Honestly the only difference between the graphics on the 2 laptops you picked is that the chip on the Asus has a 200 MHz faster clock speed and can do 3D, and has twice the memory.
You should also note that on some computers you can set up shared memory, which can allow the video card to use some of the system RAM in addition to the video card RAM.
As for how much memory you need, I'd read this article:
