  1. ^abcBoost values (if available) are stated below the base value initalic.
  2. ^Texture fillrate is calculated as the number ofTexture Mapping Units multiplied by the base (or boost) core clock speed.
  3. ^Pixel fillrate is calculated as the number ofRender Output Units multiplied by the base (or boost) core clock speed.
  4. ^Precision performance is calculated from the base (or boost) core clock speed based on aFMA operation.
  5. ^Officially declared performance is twice the one shown here due to the use ofsparsity.
  6. ^Unified shaders :Texture mapping units :Render output units :Ray accelerators :AI accelerators andCompute units (CU)
  7. ^Officially declared half-precision performance is twice of the one shown here due to being based on different operation (a×b+c×d+e).
