Qualcomm S3 and S5 Gen 2 chips for augmented reality glasses have been unveiled

تراشه‌ های Qualcomm S3 و S5 Gen 2 برای عینک‌های واقعیت افزوده رونمایی شد

As you know, Qualcomm recently unveiled its Snapdragon 8 generation 2 chip, and among all the performance figures released from this chip, Bluetooth performance and its interaction with other devices were important. But in the meantime, other chips such as Qualcomm S3 and S5 Gen 2 were released for wireless headsets, which are not without grace. Qualcomm’s new chips have given rise to a new platform for wearable gadgets, specifically AR glasses, which the company itself discussed yesterday.

  • Snapdragon 8 generation 2, the most advanced 5G platform, was officially introduced by Qualcomm
  • Qualcomm’s 12-core desktop processor leaked and launched in 2024

What are the features of Qualcomm S3 and S5 Gen 2 chips?

With its new second-generation platform, Qualcomm has focused especially on Bluetooth LE Audio capability. The company’s new chips can work with Snapdragon 8 generation 2 and deliver lossless sound from the device’s phone.

Of course, this is not the only unique feature of this product. These chips support dynamic head tracking to enable spatial audio for a more immersive experience on your gadget. They also have improved active noise cancellation that comes with speech recognition and when your gadget detects that someone is talking to you, it turns it on so you can hear the voice without having to manually disable ANC. .

The S3 and S5 Gen 2 chips are also designed with a special focus on areas such as gaming. Latency on these chips has gone from 68ms on Gen 1 to 48ms (and an audio back channel for good quality in-game chat).

These chips also support the Auracast feature, which is the Bluetooth version of FM radio. A single transmitter can transmit to multiple receivers on different frequencies, and there is no need to pair the desired devices in advance, just set it up. This feature can be used to share music with friends, connect to TVs outside the home (for example at the club or airport), listen to public announcements in different places, etc. to be used.

Qualcomm S3 Gen 2 and S5 Gen 2 are designed for stereo headsets with support for lossless audio that can be used in wireless speakers.

Snapdragon AR2

Qualcomm’s new XR chip was announced alongside the Meta Quest Pro (the company has now unveiled the Snapdragon AR2 Gen 1 platform) and, as the name suggests, focuses on augmented reality glasses.

As thin and light designs for augmented reality glasses and gadgets are a priority for manufacturers as well as ordinary people, Qualcomm split its platform into multiple chips. In this way, the main processor occupies 40% less space on the PCB. The company has managed to keep the power consumption of its products under control (there was a problem with multi-chip designs) and has also claimed to be able to power AR glasses while consuming less than 1 watt of power. The system uses half as much power as the older XR2 that powered the Quest 2.

Latency-sensitive tasks are performed on the glasses, and heavy tasks are delegated to a Snapdragon-equipped phone or PC or other host device.

Part of the AR2 Gen 1 functions include 6DoF and hand tracking. This can be done with up to 9 cameras and an AI accelerator that helps reduce latency. There’s also an AR coprocessor that can handle eye tracking and iris authentication, which enables the Fovid rendering feature.

To connect it to other chips, Qualcomm used the FastConnect 7800 system, the same system inside the Snapdragon 8 Gen 2. It brings Wi-Fi 7 (802.11be) support with less than 2ms latency between the glasses and the host device.

Qualcomm worked closely with Microsoft during the development of the Snapdragon AR2 platform. The AR2 has caught the attention of several other companies that are developing glasses based on the new platform. Companies such as Lenovo, LG, Nreal, Oppo, Pco, QONOQ, Rokid, Sharp, TCL, Tencent, Vuzix and Xiaomi.
