XDNA is the name for AMD's neural processing unit microarchitecture. It is based on IP blocks from Xilinx, a company which was acquired by AMD in 2023.

As of 2024, XDNA is implemented in AMD's consumer PC processors (branded as Ryzen AI), as well as the AMD Alveo V70 AI accelerator.

Generations

This section needs expansion with: Architectural details, from the source(s). You can help by adding to it. (August 2024)

First

First-generation XDNA, initially implemented in the Ryzen 7040 series mobile processors, provides up to 10 TOPS of processing performance. The Ryzen 8040 series (codenamed "Hawk Point"), a refresh of the Ryzen 7040 series, features a higher-clocked XDNA NPU providing 16 TOPS of performance.

XDNA is also used in AMD's Alveo V70 datacenter AI inference processing card.

Second

XDNA 2 was introduced in the Strix Point Ryzen AI 300 series processors. The NPU provides up to 50 TOPS of processing power, and the implementation is labelled by AMD as the third generation of Ryzen AI.
