I'm looking for a laptop that has dedicated video memory. I keep seeing discrete - is that the same thing?

What does Discrete Memory mean in respect to graphics cards?
Discrete memory means the video memory is not used from the computer's memory (RAM). It will come with its own memory.





Graphics card with discrete memory will perform better.





If you buy a laptop say 512MB RAM with shared graphics memory of 128 MB, this effectively means that the available RAM for other process will be 396 MB.
Reply:if you are looking for those types of vedio memory, then please get some big 512 or more of the vedeo ram, other wise it will create problems.
