I would like to find out what is the CPU speed (GHz) of A80 chip on Pcduino8 (beta).

Also, is the Pcduino8 board circuitry meant to operate at the same speed as the CPU speed ?

Thanks & best regards,

Nicholas Chua

yes,I have checkout board,I used commend "cat /proc/cpuinfo",I finded that:

It has 8 core,and every core has bogomips=4800,It means that the CPU frequency = 4800*25/50000 = 2.4G
