Does ram from graphic cards contribute to overall ram on computer?
RAM from graphic cards does not contribute to overall RAM on a
computer. A graphic card that has RAM will only use that RAM for
the use of the graphic card itself and no other parts of the
computer. This means that the RAM that is on the graphic card is
only used to store images that are being sent to the graphic card
itself. The RAM on the graphic card allows the card to handle much
more graphic intensive scenes, and puts a lot less stress on the
graphic card, because instead of the graphic card having to process
every bit of information for the scene that is sent to it. ( lets
say your graphic card as 1GB of RAM on it ) The graphic card can
store at least 1 GB of RAM in its memory to process later, allowing
the card to finish processing the information that it was
processing before the new information came in. Hope this helps.
