PHYSIX OBSERVATION

Arm is shifting from selling pure IP to providing turnkey system-level solutions to address on-device AI fragmentation. By positioning the CPU as an orchestration engine and embedding NPU capabilities into the GPU, Arm aims to open a new front beyond the NPU compute arms race. While this vertical integration of hardware and software may accelerate vendor differentiation, it risks deepening industry path dependency on Arm's underlying architecture; stakeholders should scrutinize whether its ecosystem openness truly matches marketing claims.
