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
= First
