Google says Chromecast Ultra is 1.8 times as fast as the last model, and it also includes Ethernet support through a dongle. Google Play Movies will also get 4K support soon to provide content to the new Chromecast, and it'll offer HDR with the Dolby Vision standard.

Chromecast Ultra will be available in November, where it's going to go head-to-head with Roku's new players, Amazon's 4K Fire TV devices and potentially a new Apple TV.
