The Nitty Gritty (Raspberry Pi 3 Specs, Benchmarks & More)


The Raspberry Pi 3 is here and it has already sold more than any other Pi! Not only is it more powerful and bluetooth capable, it also comes with USB 2.0 ports and wireless internet. This post will attempt to breakdown the hardware specifications and benchmarks to help you fall more deeply in love with the Pi 😊. Please feel free to watch the YouTube videos we've embedded and, as always, please subscribe!

Ports: HDMI, 3.5mm analogue audio-video jack, 4× USB 2.0, Ethernet, Camera Serial Interface (CSI), Display Serial Interface (DSI)

Wireless Signals

As mentioned before, this Raspberry Pi comes packed with WiFi antennas. The wireless chips markings can only really be seen through magnifying glass. However, the Broadcom BCM43438 chip provides 2.4GHz 802.11n wireless LAN, Bluetooth Low Energy, and Bluetooth 4.1 Classic radio support. This is in part due to the fact that these features are built directly onto the board to keep costs down. 
Like the wireless chip, the Pi's antennas are wired directly to the board and and are found near the side. Despite their size, they are more than capable of picking up signals through walls. This goes for WiFi as well as bluetooth.



SoC

The processor found in the Pi was built specifically for the Model 3b and includes four ARM Cortex-A53 processing cores running at 1.2GHz with 32kB Level 1 and 512kB Level 2 cache memory, a VideoCore IV graphics processor. All of these cores are then linked to a 1GB LPDDR2 memory module on the rear of the board. This will allow for multi-application processing as well as the ability to watch HD video.

Other hardware

There is also a 40 pin general purpose input-put panel found near the rear of the Pi. This could allow for more experienced programmers to connect hardware for projects. In addition to the GPIOs, there is an ethernet port, USB chips for the four USB inputs, and a an additional chip that allows USB to function as an ethernet port.

Benchmarks

The following graphs were found on the Raspberry Foundation's website and show the Pi's performance next to previous models as well as competitors.
