AMD Pitches Unified Memory To Cut Physical AI Control Loop Overhead
At ECS 2026, held August 27 and 28 at a Tokyo hotel, AMD laid out its physical AI strategy and put a Unified Memory architecture at the center of it, with the NPU and CPU sharing one memory space and the GPU sharing the same pool. The company argues external NPUs and GPUs on small systems force repeated exchanges over PCI Express or slower interfaces, and that overhead limits how fast the sense, infer, decide, act loop can run.
