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