Notes
  1 - All GPU vendors use a unified architecture for their DX11 chips - this means execution units are used to process all kinds of components (vertex, geometry and pixel).  Previous architectures had    pipelines of units dedicated for each type of component.
  2 - This model is composed of two GPUs.  The performance figures are calculated for when operating in AFR (alternate frame rendering) mode.
   3 - The GF1xx execution units contain a set of ALUs on two pipelines per unit.
  4 - The GF1xx texture units run at half shader clock speed and can filter 4 times the number of texels that can be addressed.
