History
The Ryzen AI 9 HX 475 emerged as part of AMD's strategy to capitalize on the AI PC revolution, pushing the performance envelope of mobile chips. Following the success of the Strix Point (300 series), the 475 refines the hybrid core concept, ensuring that even the most demanding AI and productivity workloads can be handled without a discrete GPU. It represents a shift where the NPU is no longer a co-processor but a first-class citizen in the compute hierarchy.
Improvements over Previous Generation
- Higher boost clock speeds
- Increased core count (12 vs 12, but optimized 5c cores)
- Refined power management for better sustained performance
- Updated RDNA 3.5 graphics drivers
