Zusammenfassung:	The AMD Ryzen 7040 series is the first x86 processor with an integrated neural processing unit (NPU). The AMD XDNA technology in the NPU of Ryzen artificial intelligence (AI) processors provides optimized compute and memory resources for the needs for AI workloads and a specialized data movement architecture that allows to minimize bandwidth requirements leading to higher performance and efficiency. Across a selection of neural network benchmarks, XDNA provides between 4.3× and 33× better performance per watt, leading to extended battery life. The AI-optimized capabilities of the Ryzen 7040 NPU enable new AI experiences that are not possible without XDNA, making it a fundamental component in today’s Ryzen-AI-powered devices and setting the foundation for an exciting roadmap toward future AI capabilities in mobile PCs.
