Raspberry Pi 3 model B Launch – 64-bit quad-core ARM Cortex A53

Raspberry Pi 3 model B launch is today’s big news. The new Pi sports a 64-bit quad-core ARM Cortex A53 CPU with VideoCore IV GPU packaged into the new BCM2837 chip. This 1.2GHz CPU offers ~50% speed improvement over the Pi 2’s BCM2836.

Now With Built-in WiFi & Bluetooth

The other major news is that the Raspberry Pi 3B now has built-in 802.11n WiFi and Bluetooth 4.0 courtesy of the very shiny (and very hard to photograph so you can actually see the writing) new BCM43438 chip on the underside of the board.

What About The Price?

It’s also the same traditional Raspberry Pi model B base price of $35 plus shipping and local taxes.

Full Specifications

Silicon

  • New BCM2837 chip
  • Quad-core 64-bit ARM cortex A53 CPU
  • Clocked at 1.2GHz
  • ~50% faster than Pi 2
  • 400MHz VideoCore IV GPU
  • 1GB LPDDR2-900 SDRAM
  • New BCM43438 chip for WiFi/BT
  • 802.11n Wireless LAN
  • Bluetooth 4.0

Connectivity

  • 26 GPIO ports in the standard 40-pin Pi configuration
  • 4 USB 2 ports
  • 100Base-T ethernet
  • DSI port
  • CSI port
  • 4-pole composite video/audio
  • HDMI 1.4

Power

  • Micro-usb power in
  • 2.5 Amp supply recommended

While we’re on the subject of power, I’ve done some preliminary measurements and will publish my findings in full with updated charts and some new tests in a day or two. The Pi3B uses virtually the same amount of power as the 2B until you start hammering those A53 CPU cores. The 4 cores appear to use 100-110 mA each when heavily loaded (compared with the Pi2B’s 40-50 mA per core).
