Hi,
Great question! Processing & Picture: U8000F uses the Crystal Processor 4K with 4K upscaling and Color Booster, while Q8F steps up to the Q4 AI Gen1 Processor with Quantum Dot technology, Quantum HDR+, Dual LED, and Color Booster Pro for richer color, deeper contrast, and wider viewing angles.
Motion & Gaming: Both include Motion Xcelerator (60Hz), but Q8F adds Game Motion Plus, Game Bar, Mini Map Zoom, Super Ultra Wide Game View, and AI Auto Game Mode.
Audio: Each has 20W 2-channel speakers with Object Tracking Sound (OTS) Lite; Q8F enhances with Adaptive Sound and Active Voice Amplifier for more immersive audio that adapts to your space.
Smart Features: Q8F adds Multi View, Daily Board, Generative Wallpaper, Art Store, and built-in Google Cast.
Voice: U8000F supports Alexa via an external device, while Q8F offers hands-free Alexa and Bixby built-in for both hands-free and remote/push-to-talk activation.
Design & Connectivity: U8000F features a 3 Bezel-less MetalStream design with basic feet, while the Q8F uses a slimmer AirSlim build. Both models feature 3x HDMI ports, but Q8F adds 1x Optical and a second USB-A port (1x USB-A on U8000F).
I hope this helps!
