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
editThis section needs expansion with: Architectural details, from the source(s). You can help by adding to it. (August 2024) |
First
editFirst-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.[2]
XDNA is also used in AMD's Alveo V70 datacenter AI inference processing card.[3]
Second
editXDNA 2 was introduced in the Strix Point Ryzen AI 300 series processors. The NPU provides up to 50 TOPS of processing power,[4][5] and the implementation is labelled by AMD as the third generation of Ryzen AI.
