The Raspberry Pi Foundation has officially launched its latest single-board computer, the Raspberry Pi 2 Model B+ 1G, which boasts an upgraded quad-core processor and double the memory of its predecessors.

The previous generation used a Broadcom BCM2835 system-on-chip processor  with a 700MHz ARMv6 CPU, this was already an outdated chip on release but the aim was to produce a single-board computer on the cheap for enthusiasts to mess with. It became hugely successful and one of the main uses people found was an ultra cheap XBMC computer.

The BCM2835 has been replaced with a BCM2836, which bumps the stock clock speed to 900MHz and packs four physical processing cores where its predecessor had but one. More importantly, it is also based around the ARMv7 microarchitecture – which means, in theory at least, wider compatibility with mainstream Linux distributions like Canonical's Ubuntu, especially when the more capacious 1GB of RAM is taken into account.

The chip upgrade could equate to a six fold increase in performance when running ARMv6 applications.

Amazingly the Raspberry Pi Foundation have set the price as the same as the original Pi at £30 so you are getting considerably more bang for your buck. Hopefully we will get to review the new Raspberry Pi 2 in the next few weeks.
