Picture and Audio Performance
Both devices support 4K HDR with Dolby Vision and Dolby Atmos. However, Apple TV goes further by offering:
Higher bitrate video playback
Frame matching and dynamic range switching
Support for lossless audio and Spatial Audio when paired with AirPods Pro/Max
Roku Ultra shines for casual users but is limited in fine-grained calibration. For those who obsess over video accuracy, Apple’s attention to detail wins.
Smart Home Ecosystem
Apple TV is a certified HomeKit hub that supports Matter and Thread, making it the most powerful streamer for Apple-centric smart homes.
Roku Ultra works well with Alexa and Google Assistant, but it lacks native Matter support.
Winner: Apple TV 4K for users with HomePods, iPhones, or other HomeKit devices.
Operating System & Interface
tvOS 17 brings a premium, ad-free experience:
Customizable Control Center
App switching like iOS
Multiview for sports
Native support for Apple Fitness+, Apple Arcade
Roku OS is simple and fast, but supported by ads and fewer advanced features. It appeals to budget-focused or less tech-savvy users.
Performance & Gaming
Apple TV 4K uses the A15 Bionic chip for ultra-fast app loading and streaming. It also supports:
Apple Arcade
Xbox and PS5 controller pairing
120Hz output with HDMI 2.1 TVs
Roku Ultra is responsive for streaming but lacks dedicated gaming features.
Winner: Apple TV 4K for gamers or performance enthusiasts.
Voice Control: Siri vs Alexa/Google

Roku Ultra: Voice control via remote supports Alexa and Google Home routines.
Pro Tip: Apple TV’s Siri Remote lets you use commands like “Play episode 2 of Ted Lasso” or “Turn on Movie Mode.”
