Compared to the Raspberry Pi 1 it has:
- A 900MHz quad-core ARM Cortex-A7 CPU ( vs single-core 700Mhz ARM1176 CPU on Pi 1)
- 1GB RAM (vs 512 MB on Pi 1)
Like the (Pi 1) Model B+, it also has:
- 4 USB ports
- 40 GPIO pins
- Full HDMI port
- Ethernet port
- Combined 3.5mm audio jack and composite video
- Camera interface (CSI)
- Display interface (DSI)
- Micro SD card slot
- VideoCore IV 3D graphics core
Price tag is the same, around $35. However, connectors are more easier to access, ie: located in a better way (see photos in this post), and the SD card has been replaced by a micro SD.
So it is worth getting a Pi 2 vs a Pi 1? Yes, definitely! Unless you have only SD card left and do not want to buy a micro SD you should really go for a Pi 2 for the same price of the Pi 1!
Various benchmarks over internet show that the Pi 2 is about 6 times faster than a Pi 1. However compared to “regular” small PCs such as NUC, the Pi 2 is much slower (and cheaper).
