Qualcomm Snapdragon AR2 Announced for AR glasses  – 40% smaller PCB & 50% improved power efficiency

Sharing is caring!

One of the more exciting announcements from the Snapdragon Summit 2022, Qualcomm has announced the new Snapdragon AR2, which will complement the Snapdragon XR2+ Gen 1 chipset that is used to power VR headsets such as the Meta Quest Pro.

This is the world’s first purpose-built head-worn augmented reality platform. Qualcomm have focused on two of the main areas for this product class. The ground-breaking multi-chip architecture achieves 50% lower power consumption and 2.5x better AI performance to enable high-performance, sleek AR glasses.

The Company built Snapdragon AR2 from the ground up to revolutionise the head-worn glass form factor and usher in a new era of spatial computing experiences for the real-world/metaverse mix.

The main processor occupies a 40% smaller PCB area on glass, and the overall platform delivers 2.5x better AI performance while consuming 50% less power to help achieve AR glasses that consume.

To better balance the weight and decrease the arm width on either side of the glasses, Snapdragon AR2 uses a multi-chip architecture that includes an AR processor, AR co-processor and connectivity platform. Snapdragon AR2 dynamically works to distribute the processing of latency-sensitive perception data directly on the glasses and offloads more complex data processing requirements to a Snapdragon-powered smartphone, PC or to other compatible host devices.

The AR processor is optimised for low motion-to-photon latency while supporting up to nine (9) concurrent cameras for user and environmental understanding. Its enhanced perception capabilities include a dedicated hardware acceleration engine that improves user motion tracking and localisation, an AI accelerator to reduce latency for sensitive input interactions such as hand tracking or 6DoF, and a reprojection engine for a smoother experience.

The AR co-processor aggregates camera and sensor data and enables eye tracking and iris authentication for foveated rendering, to optimise workloads only where the user is looking. This helps reduce power consumption.

The connectivity platform utilises Qualcomm FastConnect 7800 connectivity system to unlock the world’s fastest Wi-Fi 7 technology available and reaches

Snapdragon AR2 is in various stages of development with OEMs including Lenovo, LG, Nreal, OPPO, Pico, QONOQ, Rokid, Sharp, TCL, Tencent, Vuzix and Xiaomi.
