Raspberry Pi 3
The latest version of the the Raspberry Pi, the $35 credit card-sized computer, launches today.
The big change is the move to a newer and faster quad-core processor – some 50 percent faster than that in the Raspberry Pi 2 – and the addition of wi-fi and Bluetooth for the first time.
Here you can see the new board. Step through the rest of the images to walk through what’s new with the Pi 3.
Read the full interview with Raspberry Pi co-creator Eben Upton about how the Pi 3 changes what’s possible with the Pi.
Faster CPU
One of the major changes from the Raspberry Pi 3’s predecessor – the Raspberry Pi 2 – is the move to upgrade the core Broadcom chip.
The Pi 3 sees the board move to a 1.2GHz quad-core 64-bit ARM cortex A53 CPU. Not only is the CPU faster than the Pi 2’s 900MHz quad-core ARM Cortex-A7 CPU, but it is based on an architecture that can do more in each processor cycle. A 400MHz VideoCore IV multimedia processor handles the Pi 3’s graphics.
The new CPU core in the Raspberry Pi 3 performs 50-60 percent faster in 32-bit mode compared to the Raspberry Pi 2 and roughly ten times better than the original single-core Raspberry Pi in a multi-threaded CPU benchmark like SysBench. Compared to the original Pi, real world applications will see a performance increase of between 2.5x – for single-threaded applications – and more than 20x – for NEON-enabled video codecs.
Wi-fi comes to the Pi
Wi-fi comes to the Pi
The biggest new addition to the board is support for wi-fi (802.11n Wireless LAN) and Bluetooth 4.1.
The chip antenna providing this wireless connectivity can be seen behind the ‘Made in the UK’ stamp. The Raspberry Pi Foundation manufactures boards out of a Sony factory in Pencoed in South Wales.
Audio and video

New power supply
New power supply
Peak power consumption of the Pi 3 is about 50 – 60 percent higher than the Pi 2, so a new power supply has launched for the board.
The new supply will be rated at 2.5A5.1V, compared to the 2A5V-rated supply used by earlier boards.
Pi case
The layout of the Pi 3 has stayed the same, apart from the LEDs moving. This move was necessary to make space for the antenna for the wireless LAN.
The change means some cases for older boards will not have holes in the right place to show the LEDs. The Raspberry Pi Foundation is launching a new official case for the Pi 3, seen here.
