Hi JoJo! There are three major differences between the TU7000 and the TU8000. First, the TU8000 features voice control capabilities using Bixby, Google, or Alexa. The TU8000 also features extra connections with 3 HDMI, instead of two, while adding a set of composite (Yellow, White, Red) connections. Finally, the TU8000 adds Ambient Mode taking your QLED TV screen from black to color like a screensaver, blending it in with your TV wall design when your TV isn’t in use. ^Tim
