The "new" Raspberry Pi has remained the same from SoC and Ram, therefore he is not faster than the previous B-model. However, the USB ports have been improved: there are now 4 instead of 2 ports, and the power of the ports is better, that many things are going now, even without external USB hub: I, for example, a webcam drangehängt that the old model with stroke worked properly. Went even without using the B +. Very nice is the fact that the external connections are now only on 2 sides and not on all 4 as its predecessor. The SD card slot has been replaced by a micro SD slot with "sticky keys", which is really very pleasant. In addition, this is the card no longer.
