Raspberry Pi 3 photos: A closer look at the new board

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

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

The Pi 3 retains the combined 3.5mm audio and composite video port found on the Pi 2.

USB hub

As with previous Pis, the board's USB and Ethernet connections are handled by this SMSC chip.

This shared bus limits the data that can be passed to and from the Pi and can bog down data transfer rates when a user attempts to simultaneously pass large amounts of data over Ethernet and to a USB-attached device.

Ports

The Pi 3 keeps the micro-USB port for power and the HDMI output found in the Pi 2.

Peripherals and networking

The four USB2 ports and 10/100 Ethernet remain the same as the Pi 3's predecessor.

Expandability

The Pi 3's 40 general purpose input-output pins expand the range of hardware that can be used with the board, as was the case with the Pi 2.

Display interface

The Pi 3 also keep the same display interface found on the Pi 2.

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.
