Generations
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.
