Raspberry Pi 3 Model B
The Raspberry Pi 3 Model B is the third generation Raspberry Pi with a 64-bit 1.2GHz quad-core processor, 1GB of RAM, WiFi (b/g/n), and Bluetooth 4.1!
- 1.2GHz 64-bit quad-core ARM Cortex-A53 CPU (BCM2837)
- 1GB RAM (LPDDR2 SDRAM)
- On-board Wireless LAN - 2.4 GHz 802.11 b/g/n (BCM43438)
- On-board Bluetooth 4.1 + HS Low-energy (BLE) (BCM43438)
- 4 x USB 2.0 ports
- 10/100 Ethernet
- 40 GPIO pins
- Full size HDMI 1.3a port
- Combined 3.5mm analog audio and composite video jack
- Camera interface (CSI)
- Display interface (DSI)
- microSD slot
- VideoCore IV multimedia/3D graphics core @ 400MHz/300MHz
With the ARMv8 processor it can run the full range of ARM GNU/Linux distributions, including Snappy Ubuntu Core, as well as Microsoft Windows 10 IoT edition.
You will need the latest NOOBS image (1.8.0) for the Wireless LAN and Bluetooth drivers to be installed.
Compared with the Raspberry Pi 2 the CPU is running at a 33% faster clock rate (1.2GHz vs 0.9GHz) the more modern core also means a more efficient instruction set, especially when performing operations on 64-bit values.
Video and 3D performance has also seen a bump with the VideoCore being clocked at 400MHz for video processing (up from 250MHz) and the 3D graphics processor running at 300MHz (up from 250MHz).
In general use you can expect the Raspberry Pi 3 to perform around 50% quicker than the Raspberry Pi 2 running the same software. In the future as software adds optimisations for the architecture the gap will widen further.
Wireless LAN, Bluetooth, and oh my!
The biggest change is the inclusion of integrated Wireless LAN and Bluetooth 4.1 on board adding two great connectivity options straight out of the box. The Wireless LAN should be compatible with all home network setups and is supported in the latest NOOBs image.
We've achieved speeds of around 40Mbit/sec using the new built in adaptor which is similar to the speeds we see with USB Wi-Fi dongles in the same setup.
Bluetooth will allow you to use a wireless keyboard/trackpad without extra dongles, keeping things nice and tidy.
GPIO and layout
The GPIO header and layout remains the same as before so all of your existing HATs and add-on boards will work fine with the Raspberry Pi 3.
