Amlogic, which produces chips commonly used in Chromecast devices, has announced a brand new design that could bring a range of upgrades with it. 

The next-gen Amlogic chip, the S905X5, could mean features such as HDMI 2.1 and VRR might come to Chromecast devices in the future. 

The company’s newest version of the chip was revealed as part of a reference box shown by Sei Robotics at IBC 2023.

The reference box shown off by Sei Robotics supports HEVC, AV1, and VVC video decoding as well as HDMI 2.1 and its associated features. This includes VRR, eARC, and QMS functionality.
