The Raspberry Pi 2 Model B is built around the ARMv7 processor, a 900MHz quad-core ARM Cortex-A7 CPU enabling the Raspberry Pi to run a vast range of ARM GNU/Linux distributions, including Snappy Ubuntu Core, as well as Microsoft Windows 10. The upgrade of processor in this platform, from BCM2835 (single core ARMv6) to BCM2836 (quad core ARMv7), means 2X increase in performance. The board also comes with a full gigabyte of RAM, which will greatly improve games and web-browser performance.
The board is powered through a USB Micro power supply. The power supply requires to provide at least 700mA at 5V. The Raspberry Pi 2 has an identical form factor to the previous (Pi 1) Model B+ and has complete compatibility with Raspberry Pi 1.
