Automotive SoC Comparison 2026 - ADAS

Analyzed devices:

• Horizon Robotics Journey 6E
• Tesla FSD HW4
• Qualcomm SA8650P
• HiSillicon Ascend 610

 

In recent years, ADAS applications have increasingly relied on high-performance System-on-Chips (SoCs) to address the growing computational requirements of perception, sensor fusion, and decision-making functions, while meeting stringent automotive constraints.

This comparative report synthesizes the results of physical, technical, supply chain, and costing analyses of a selection of ADAS SoCs, including Horizon Robotics J6E, Tesla FSD HW4, Qualcomm SA850P, and HiSilicon Ascend 610. These components represent both merchant silicon solutions and vertically integrated designs developed for advanced driver assistance and automated driving systems.

The report compares the main technical choices at the system, device, and wafer levels, as well as the manufacturing processes, highlighting both common strategies and key differences across suppliers.

The analysis assesses how these technical and manufacturing choices impact product positioning and competitiveness, showing that ADAS SoC differentiation is driven by architectural decisions, integration strategy, and cost structure.

For each analyzed component, the report details the SoC architecture, manufacturing process, and key technical trade-offs, supported by a cost analysis estimating the manufacturing cost structure.
