The new SoC is the BCM2837, a quad-core 1.2GHz 64-bit ARMv8-A Cortex-A53 (up from a quad-core 900 MHz ARMv7 in the Pi 2) which, at face value, should represent a jump of about a 33% in performance.
Video and 3D performance has also seen a bump with the VideoCore being clocked at 400MHz for video processing (up from 250MHz) and the 3D graphics processor running at 300MHz (up from 250MHz).
One of the most welcome changes will be the addition of onboard WiFi and Bluetooth. The WiFi is compatible with 2.4GHz 802.11 b/g/n networks and the Bluetooth 4.1 supports BLE (Bluetooth Low Energy) both are supplied by the BCM43438.
Elsewhere, everything is pretty much the same as the Pi 2. There's the 4 USB 2.0 ports, 10/100 ethernet, HDMI port, combined 3.5mm analog audio and composite video jack, CSI and DSI connectors for cameras and displays respectively, the microSD slot (which is now not spring-loaded), and the same 40 GPIO pins.
