The Raspberry Pi 3 is available on sale at official partners and resellers online such as Amazon for $35. The new board is the first 64-bit Raspberry Pi, that comes with built-in Wi-Fi and Bluetooth.
This new Raspberry Pi 3 is powered by Quad-core 64-bit ARM Cortex A53 clocked at 1.2 GHz, 1GB LPDDR2-900 SDRAM (i.e. 900MHz), 802.11n Wireless LAN with Bluetooth 4.1 (including Bluetooth Low Energy) and 400MHz VideoCore IV multimedia. This Raspberry Pi 3 is Roughly 50% faster than Raspberry Pi 2. It has complete compatibility with Raspberry Pi 1 and 2.
The new Raspberry Pi 3 seems to have crossed a performance threshold. Despite not adding the 1GB of on-board RAM provided by the Raspberry Pi 2, this board seems to have become “good ” to replace a desktop PC for most people, most of the time.
Perhaps the biggest change is that the Raspberry Pi 3 comes with both built-in Wi-Fi and Bluetooth 4.1. Which means that the new board will also support Bluetooth “Classic” and, somewhat more usefully, Bluetooth LE. Which makes the Raspberry Pi 3 not just a desktop replacement, but it is a perfect hub for the emerging Internet of Things.
All of the connectors are in the same place and have the similar functionality, and the board can still be run from a 5V micro-USB power adapter. Apart from the position of the LEDs, and the radio chip and antenna — located between the display connector and the GPIO headers — the board looks very similar to the Raspberry Pi 2.
