Is the iPhone 5's A6 Chipset a Quad Core?

I don't get it. Some bloggers are saying it is while other bloggers are saying it's a dual core. But then again, why would Apple release a dual core phone?

Apple won't say, its all speculation
they won't say how many cores, what the clock speed is, or anything.

Agreed with the previous answer.
It's correct that Apple won't be showing off the A6 Chip capacity but it is said that the graphics and apps performance will be improved drastically with this new little hardware.
Read that the A6 should be twice as fast as the previous versions.
