"There are two parts to the new ThinkReality system -- the AR headset and a software platform. The ThinkReality A6 is a comfortable 380-gram headset with two fisheye cameras on the front, as well as depth sensors and a 13-megapixel RGB sensor. There's also microphones onboard for voice control, and the headset can also detect where you're gazing to optimize resolution or navigation. You'll also be able to interact with your virtual environments using an included 3DoF controller. Untethered, the A6 can last up to four hours with its 6,800mAh battery, and you can still use the device while it's plugged in and charging.Lenovo launches ThinkReality AR and VR headset for enterprises | Engadget
The headset connects to an SSD-sized compute box that contains a Snapdragon 845 CPU running an Android-based platform. There's also an Intel Movidius chips powering waveguide optics here, and each eye on the A6 offers a 40-degree diagonal field of view and 1080p resolution. By comparison, the HoloLens 2 uses a Snapdragon 850 CPU and packs two 2K MEMS displays. Microsoft also squeezes all the computing components into the headset rather than in a separate box like Lenovo does. While I'm not a fan of having to carry around an additional accessory to power a headset, this setup does make the ThinkReality A6 lighter, so it's a compromise I'm willing to make."
