This is very simple and easy to understand the main difference between 32 and 64 Bit Processors....

On a 32-bit operating system, you are restricted to a maximum of 8 gigabytes of RAM. On a 64-bit operating system, you really do not have a limit. Let’s look at Wikipedia and find out the maximum amount of RAM for a 64-bit operating system:

264 addresses, equivalent to approximately 17.2 billion gigabytes, 16.3 million terabytes, or 16 exabytes of RAM.

More Simplified as:
Here's a simplified summary of the situation:

Almost all new servers sold within the last two years from AMD or Intel will have x64 capability.
Most mid- to high-end desktop processors from AMD or Intel within the last year have x64 capability.
Some higher-end Semprons have x64; lower-end Semprons do not.
No AMD Durons have x64.
All AMD Opteron processors have x64.
All AMD X2, FX, and Athlon64 chips have x64.
All Intel Pentium D and Celeron D chips have x64.
All AMD Turion notebook processors have x64.
All Intel Core 2 processors (mobile, desktop, and server) have x64.
No Intel Core Duo notebook processors have x64
No Intel Pentium M notebook processors have x64.

Now every new laptop which is been soled has a x64 Processor and can also run x86 OS too....so now you have choice that you run a x64 or x86...remember one thing that while running x64 you must have a x64 Software's Setup.
