[comp.sys.ibm.pc.misc] vga speed

pasquale@sgl (Pasquale Leone) (01/07/91)

   I've seen many articles in the pc trade mags comparing the
   speed of various VGA cards and other articles comparing the
   speed of various 8514 cards and yet other articles comparing the
   speed of TMS34010 cards.

   As the owner of an ATI VGA1024 card who is thinking of buying
   a smart graphics card(8514, etc) I would like to know if
   it is worth the money. What I mean is how much faster is
   an 8514 going to be than my VGA. 10% ?  Twice as fast ? 10 times as fast?

   Can anybody out there who has access to both a VGA equiped machine
   and one with a graphics coprocessor board please tell how
   much faster one is than the other.

   As a test consider having a full screen window (say notepad) in
   windows 3.0 that you then iconize. All of the backgorund windows and icons
   must be redrawn. How fast is it? Or consider just moving a window
   diagonally across the screen.

   If this has already been done in some article somewhere please
   let me know.
