What is the difference between the snapdragon 805 and the 64-bit?

Just asking for the difference and what you would suggest since upcoming phones like the galaxy s5 and iphone 6 are coming

The snapdragon 805 is a 32 bit chip mainly used in phones, while the 64 bit chips are used in computers but have recently been released in the iPhone 5s and iPad Air
A 64 bit chip can handle more tasks and will be faster. It isn't really necessary in mobile phonedms or tablets now though but might be in the future.
