- ^ a b c Boost values (if available) are stated below the base value in italic.
- ^ Texture fillrate is calculated as the number of Texture Mapping Units multiplied by the base (or boost) core clock speed.
- ^ Pixel fillrate is calculated as the number of Render Output Units multiplied by the base (or boost) core clock speed.
- ^ Precision performance is calculated from the base (or boost) core clock speed based on a FMA operation.
- ^ Officially declared performance is twice the one shown here due to the use of sparsity.
- ^ Unified shaders : Texture mapping units : Render output units : Ray accelerators : AI accelerators and Compute Units (CU)
- ^ Officially declared half-precision performance is twice of the one shown here due to being based on different operation (a×b+c×d+e).
