Thankfully, the Edge's GPU is not only discreet, but also powerful and (thankfully) not fragmented between the two models: an NVIDIA GT640M LE powers thegraphics on both, while 4GB or 8GB (respectively) of DDR3 RAM keeps it all running smoothly.
The smaller models of the Digital Studio series use a built-in graphics adapter in the Intel 810 chipset, the circuitry that is normally used to control other components of the motherboard such as the PCI bus, and the serial and parallel ports.
