  1. ^ Texture fillrate is calculated as the number of Texture Mapping Units multiplied by the base (or boost) core clock speed.
  2. ^ Pixel fillrate is calculated as the number of Render Output Units multiplied by the base (or boost) core clock speed.
  3. ^ Precision performance is calculated from the base (or boost) core clock speed based on a FMA operation.
  4. ^ The effective data transfer rate of GDDR5 is quadruple its nominal clock, instead of double as it is with DDR memory.
  5. ^ Unified Shaders : Texture Mapping Units : Render Output Units
