This is how the new Raspberry Pi 4 looks like (also compared to the Rai 3B+ and the Pi Zero)! You need a new power supply and also a new monitor adapter: The one from the Pi Zero won't work!
What's new on the Raspberry Pi 4:
• Gigabit Ethernet
• 2 USB 3.0 ports
• 2 Micro HDMI ports
• Bluetooth 5 LE
• USB-C power supply
