The Raspberry Pi 2 Model B is a 900MHz quad-core ARM Cortex-A7 Pi with 1GB RAM. This is a dramatically enhanced raspberry pi which provides a very responsive desktop experience.
It also retains a lot of features of the Model B plus as well.
4 USB ports
40 GPIO pins
Full HDMI port
Combined 3.5mm audio jack and composite video
Camera interface (CSI)
Display interface (DSI)
Micro SD card slot
VideoCore IV 3D graphics core
Externally the new Raspberry Pi 2 Model B looks a lot like the B+.
The New Raspberry Pi 2 is significantly faster than any previous raspberry pi. This is very evident when you get into applications that perform complex arithmetic like wolfram alpha or mathematica.
Calculating the first million digits of Pi is quite a simple task.
If you are following along the command is
Now how about big primes… Now i realize that this is not a really big prime but it is a hefty computation for a computer the size of a credit card. How about the five trillionth prime? That would be five with twelve zeros.
Again if you are trying this the command is
The result is 158,308,642,985,671
If you happen to have an existing raspberry pi and want to get your image up to date for the new hardware its as simple as
sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade
Then you can put your existing SD card in your new raspberry pi 2 model b and boot it up.
You may be wondering how it stacks up in the world of microcontrollers. Here it is with small group of arm based microcontrollers. Currently the Raspberry Pi 2 Model B leading the pack when it comes to desktop performance with the Pcduino 3 running a close second.
