The banana clip that is standard issue with the AK-47 holds either 30 or 32 rounds, I can't remember which. 30 for sure; fine tuning of this answer welcomed by someone more in the know.
Cyclic rate of fire about 600 per minute.
The original AK-47 had a cyclic rate of fire of 700 rounds per minute. The "modernized" AKM (manufactured from 1959 onwards) had a cyclic rate of fire of 600 rounds per minute. Cyclic rate of fire meaning that, if you had a magazine with such a capacity loaded, and you just held down the trigger, and you could fire off as many rounds without the weapon overheating and becoming defective.
600 rounds per minute, (10 bullets in a second)
In which regard? The AK-47 has a rate of fire of about 700 rounds per minute - the more common AKM (often mistakenly referred to as an AK-47) has it reduced to 600 rounds per minute. The Browning M2 HBAR machine gun has a rate of fire of 450 to 575 rounds per minute, while the A/N M2 fires up to 850 rounds per minute, and the A/N M3 variant fires up to 1200 rounds per minute.
As fast as the firer is able to pull the trigger. They are semi-auto only.

You can buy armor piercing rounds for it, if you can find them.

An original AK-47 is a select-fire rifle which is capable of fully automatic fire. However, there are many semi-automatic AK variants out there, but they are not truly AK-47s. This may also be helpful: AK-47 stands for automatov kalashnikov 47, which translates to automatic kalashnikov and the 47 refers to the weapons date of Patton (1947).
