In May 2018, Qualcomm launched a devoted combined actuality chipset referred to as Snapdragon XR1, pitched at OEMs in search of “the minimum criteria for immersion” in combined actuality worlds. Today, the firm is taking a giant step ahead with Snapdragon XR2, a dramatically powered-up sequel that’s being billed as “the world’s first 5G XR platform,” and should nicely wind up powering a few of the first 5G combined actuality headsets.
Since Qualcomm presents a couple of platform for combined actuality units, it’s essential to know Snapdragon XR2’s positioning up entrance. While the XR1 was supposed to deliver the part costs down for fundamental XR headsets, it was in the end utilized in enterprise AR glasses similar to Google Glass Enterprise Edition 2 and the Vuzix M400. By distinction, the XR2 is being pitched as extra highly effective than each the XR1 and Qualcomm’s Snapdragon 835, which most notably powered the overachieving Oculus Quest headset.
According to the chipmaker, Snapdragon XR2 presents twice the CPU and GPU efficiency of the 835, over 11 occasions sooner AI processing, six occasions the video decision assist, and 4 occasions the video bandwidth, albeit with solely 4 Kryo cores — one Prime, one Gold, and two Silver — moderately than eight in the 835. Using XR2, every eye can have as much as a 3K by 3K show at 90 frames per second — a dramatic enchancment over most VR and AR headsets as we speak, and backed by quite a lot of processing energy to makes these screens helpful.
In addition to supporting foveated rendering and enhanced variable charge shading, XR2’s Adreno 650 GPU guarantees thrice the texel processing charge and 1.5 occasions the pixel processing charge of the 835, with a complete pixel throughput 2.5 occasions greater. Thanks to that throughput, XR2 helps streaming and playback of 8K movies — together with 360-degree immersive movies — at 60fps, or 4K movies at 120fps, with HDR10/HDR10+ assist. In the audio division, XR2 helps 3D spatial sound and features a customized low-power, always-on Qualcomm Hexagon DSP with voice activation and context detection talents.

XR2 additionally allows superior 3D monitoring, particularly in contrast with the fundamental 3DoF XR1. Qualcomm says it’s the first XR platform to assist seven concurrent cameras and a devoted laptop imaginative and prescient processor, enabling a standalone system to supply 26-point hand monitoring, eye and lip monitoring, and 3D room mapping, in addition to a photograph/video digital camera. It additionally features a low-latency digital camera pass-through mode, enabling clean real-time mergers of digital content material with what’s being seen by the digital camera — a key requirement for augmented actuality.
The XR2’s efficiency acquire multipliers range in comparison in opposition to the XR1, however the enhancements from technology to technology are nonetheless apparent. For occasion, the XR2’s AI engine delivers 15 trillion operations per second (TOPS) in contrast with 1.eight TOPS in the XR1 and 1.three TOPS in the Snapdragon 835. That’s an eight occasions enchancment over the XR1 in contrast with the 11 occasions acquire of the 835. On the different hand, the 835 supported 4 cameras without delay versus XR1’s three and XR2’s seven. And XR2 consists of each Wi-Fi 6 and 60GHz 802.11ay assist, whereas XR1 and the 835 have been restricted to Wi-Fi 5.
It’s price noting that XR2 clients may have the possibility of 5G assist, nevertheless it’s not a compulsory ingredient in the platform: The newest Snapdragon X55 modem will be built-in with the XR2 as wanted. Qualcomm expects some units will use it for “truly boundless XR,” splitting processing between the system and low-latency edge cloud streaming servers to supply photorealistic experiences.
Without naming particular firms, Qualcomm says that a number of OEMs have already dedicated to promoting units utilizing Snapdragon XR2, whereas others are evaluating the platform. Based on the Snapdragon 835 and XR1 experiences, the lead time between analysis and announcement could possibly be a yr, which is to say that we would start to see precise merchandise utilizing the new platform in late 2020 or early 2021. That stated, Qualcomm’s Advantage Network is now providing companions entry to each reference designs and software program packages that will assist new entrants stand up and working extra rapidly than earlier than.
