RDNA 4 is a GPU microarchitecture designed by AMD, released with the Radeon RX 9000 series on February 28, 2025.

Architecture

Packaging

Unlike its predecessor RDNA 3, AMD went back to monolithic dies with RDNA 4.

Ray tracing

RDNA 4 features the third generation of the ray tracing accelerator, doubling the number of ray-box and ray-triangle intersections and adding several performance improvements.

  1. 1 2 3 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. ↑ Officially declared performance is twice the one shown here due to the use of sparsity.
  6. ↑ Unified shaders : Texture mapping units : Render output units : Ray accelerators : AI accelerators and Compute units (CU)
  7. ↑ Formerly officially declared performance is twice the one shown here due to the use of a different operation (a×b+c×d+e).
