Don’t be fooled by the fact that the 64bit system did the task in exactly half the time as the 32bit system. It’s not just because 64 is twice as much as 32. Remember that time on the 32bit system was with Virtual Memory turned on! It is however obvious that for large multimedia processing the 64bit system is better. But for everyday usage, consider this:

32 bits:
01010101010101010101010101010101

64 bits:
0101010101010101010101010101010101010101010101010101010101010101

The letter “a” in binary:
01100001

Granted this is an overly simplistic example, so nobody chime in and say, “That’s not exactly how it works!” I know, but it’s a good visual. If your are going to use your computer for normal “office” type stuff, letters, email, the Internet, etc. Which one is the most efficient way to store and manipulate data?
The letter “a” again:

32 bit:
00000000000000000000000001100001

64 bit:
0000000000000000000000000000000000000000000000000000000001100001

Lots of wasted space huh!
