  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
