Quest 3 Is The First Headset With Snapdragon XR2 Gen 2

Quest 3 is the primary headset to characteristic Qualcomm’s new Snapdragon XR2 Gen 2 chipset.

The unique XR2 Gen 1 is utilized in virtually all standalone headsets, corresponding to Quest 2, Pico 4, Vive XR Elite, and Lynx R1. A modified variant, XR2+ Gen 1, is utilized in Quest Professional.

XR2 Gen 1 was launched in 2020, constructed on a 7nm course of node. XR2 Gen 2 is constructed on a 4nm course of node, bringing vital enhancements in efficiency and energy effectivity.

The brand new GPU has as much as 2.5x peak efficiency and double the efficiency per watt. And the brand new NPU – neural processing unit – gives as much as 8x the AI efficiency per watt for INT8.

The CPU enchancment is lots much less spectacular although, simply 33% improved over the unique XR2.

The vastly improved AI efficiency might be utilized to allow new use circumstances, corresponding to dynamic object recognition and scene classification.

XR2 Gen 2 additionally provides full on-chip {hardware} acceleration for some important headset duties:

  • Positional monitoring, considerably decreasing its energy draw and latency
  • Digicam passthrough, decreasing end-to-end latency from round 50 miliseconds to round 12 miliseconds
  • SpaceWarp movement extrapolation
  • Tremendous Decision sharpening

Qualcomm demonstrated simply how low the passthrough latency enabled by XR2 Gen 2 is by enjoying ping-pong carrying reference design headsets:

Whereas Quest 3 is the primary headset to make use of XR2 Gen 2 and Meta is Qualcomm’s strategic accomplice, Qualcomm informed UploadVR that this partnership would not embody exclusivity. Put one other manner, headsets from different corporations will use the XR2 Gen 2 in future however Qualcomm would not say exactly when.
