Raspberry Pi 3: the credit card-sized 1.2GHz PC that costs $35

Raspberry Pi foundation launches new model as it announces 8m devices have been sold in four years, making it the UK's all-time bestselling computer

The Raspberry Pi foundation has launched the latest generation of its flagship credit card-sized computer as it announced sales have topped 8m, making it the UK's all-time bestselling computer.

The Raspberry Pi 3, released on Monday, costs $35 (25), the same as its predecessor (although still seven times more than the ultra-stripped-down Raspberry Pi Zero, which was launched as a free cover gift with a magazine). In its small-form factor is a 1.2GHz quad-core ARM processor (a boost from the Pi 2's 900MHz), as well as integrated Wi-Fi and bluetooth, a first for the series.
