32bit and 64bit determines, what is the biggest number or longest word a computer can process in one step. 32bit represents big numbers, roughly all 10 digit numbers. 64bit represents very very very big numbers, roughly all 20 digit numbers.
If a computer needs to add two numbers that both have 15 digits, a 64bit computer can do it in one operation. 32bit computer needs two steps to do that. 64bit computer is twice as fast. Not all operations are twice as fast though. If you simply need to add mere millions, both will do it in one go.
To sum up – 64bit architecture allows the computer do perform some operations much faster.
