What’s New With The Raspberry Pi2 (Video) #piday #raspberrypi @Raspberry_Pi
The Raspberry Pi2 is out and includes some significant upgrades. via raspi.tv
It’s a quad-core A7 CPU with the same VC4 GPU as the original Pi. It currently runs at 800 MHz (but 900 MHz support is expected soon).
It has 1 Gb of RAM
It’s the same form-factor as the Raspberry Pi B+ (launched July 2014).
It’s fully backward-compatible with previous Raspberry Pis, so whatever you did on previous versions should work with this one.
Power use. It’s said to take similar power as the old model B. The quad-core processor makes it need a bit more juice than the B+, but the efficient B+ circuitry has been tweaked for the Pi 2. In my testing I could only make it draw 0.42A when hammering all four CPUs at once. But I suppose if you hammered the GPU at the same time you could make it draw as much as a model B.
Performance. It’s got at least 6 times more processing power than the previous Pis. Depending on how well your application can utilise a quad-core CPU, the performance gain can be much more impressive than this. For example in sorting and rearranging words in a huge text file I’ve had the Pi 2 running at 14 times the work rate of the B+.
