Silent, energy-efficient
The fanless, energy-efficient Raspberry Pi runs silently and uses far less power than other computers.

Fast networking
Raspberry Pi 4 comes with Gigabit Ethernet, along with onboard wireless networking and Bluetooth.

USB 3
Your new Raspberry Pi 4 has upgraded USB capacity: along with two USB 2 ports you'll find two USB 3 ports, which can transfer data up to ten times faster.

Choice of RAM
We're making different variants of the Raspberry Pi 4 available, depending on how much RAM you need — 1GB, 2GB, 4GB, or 8GB.
