Raspberry Pi 4 has up to 4GB RAM, a faster quad-core CPU, support for dual displays at up to 4K resolution, Gigabit Ethernet, USB3.0, wireless LAN, Bluetooth 5.0, and USB-C power. That's desktop PC performance!
The overall form factor remains the same, so you'll still be able to use HATs and pHATs as before.
1.5GHz 64-bit quad-core ARM Cortex-A72 CPU ( ARM v8, BCM2711B0)
1GB, 2GB or 4GB RAM (LPDDR4)
Onboard wireless LAN - dual-band 802.11 b/g/n/ac
Onboard Bluetooth 5.0, low-energy (BLE)
2x USB 3.0 ports, 2x USB 2.0 ports
Power-over-Ethernet (requires additional Raspberry Pi PoE HAT)
40-pin GPIO header
2× micro-HDMI ports (up to 4Kp60 supported)
H.265 (4Kp60 decode)
H.264 (1080p60 decode, 1080p30 encode)
OpenGL ES, 3.0 graphics
DSI display port, CSI camera port
Combined 3.5mm analog audio and composite video jack
Micro-SD card slot
As always with new Raspberry Pi models, you'll need the latest version of NOOBS or Raspbian to run on your Raspberry Pi 4.
The faster 1.5GHz 64-bit quad-core CPU on the Raspberry Pi 4's Cortex A72 SoC, coupled with the up to 4GB LPDDR4 RAM gives performance comparable to entry-level x86 desktop PCs. You'll see significantly faster boot speeds, and much better performance for CPU-heavy tasks like emulation and media center usage; much snappier all round!
The Raspberry Pi 4 moves to USB-C power meaning that you'll need a new USB-C power supply that can supply 5V at 3A. We've got a couple of different options: a worldwide USB-C power supply, and the official Raspberry Pi power supply.
The Raspberry Pi 4 has two USB 3.0 ports, for up to 10x faster transfer speeds than USB 2.0, perfect for connecting fast peripherals like SSDs and flash drives. There are also two USB 2.0 ports for connecting less speed-dependent peripherals like keyboards and mice.
The ethernet jack on the Raspberry Pi 4 moves to true gigabit speed, for super-speedy wired networking and, as with the Raspberry Pi 3 B+, there's Power-over-Ethernet capability too (requires additional Raspberry Pi PoE HAT).
There are dual micro-HDMI ports that support up to 4Kp60, to use your Raspberry Pi 4 with much larger displays with crisp, sharp, high resolution. Use the H.265 4Kp60 hardware decoding to watch 4K movies in your favorite media center distro.
For the first time, you'll be able to use dual HDMI displays with the Raspberry Pi. This is great for working on a bunch of different tasks at the same time without having to work in tiny windows.
If you need a micro-HDMI adapter to use your existing HDMI cable with the Raspberry Pi 4 then we've got you covered!
The shift to Bluetooth 5.0 (from 4.2 on the Raspberry Pi 3 B+) means you'll get twice the speed (2 Mbit/s) and four times the range (50m outdoors, 10m indoors) that you did with the previous generation. You'll get better power efficiency compared with Bluetooth 4.2 also.
There's dual-band 802.11 b/g/n/ac wireless LAN, like the previous generation Raspberry Pi, for quick wireless networking with less interference and better reception.
