Raspberry Pi 2 unveiled with faster processor and more memory
http://www.bbc.com/news/technology-31088908A new budget-priced Raspberry Pi computer has been unveiled, offering child coders and others a faster processor and more memory than before, but at about the same price.

The Raspberry Pi 2 Model B is roughly six times more powerful than the prior version, the Model B+, according to the British charity behind it.

Previous versions of the kit have been widely adopted by schools and enthusiasts across the world.

But the Pi faces increased competition.

Another UK-based firm, Imagination, recently released a bare-bones computer of its own, and the Arduino, Intel Galileo, Gizmo 2, BeagleBone Black and Hummingboard also form part of a growing list of rivals.

The Raspberry Pi 2 makes two major changes to the previous version, while leaving other components unchanged:

The CPU (central processing unit) is now quad-core rather than single-core. That means it can be programmed to use more of its cores to offer extra computing power, or made to use fewer to help save power consumption - useful if running as part of a battery-powered contraption. In addition, the Cortex A7 processor now runs at 800MHz rather than 700MHz
