Compared to a ODROID QuadCore the Raspi is unfortunately a lame duck.
I have all of those little ARM boards, in the field QuadCore is this Raspi the slowest.
The clock is set at 900MHz low, although there is an overclocking to 1.1 GHz, but while he was no longer stable at me.
Nevertheless, 3 stars for the competitive price, because this is really great!
