<br/>
On a 32 bit computer, 2147483648 (2^31) is the max signed integer size.<br/>
Binary: &nbsp;&nbsp;10000000000000000000000000000000<br/>
Unsigned: 11111111111111111111111111111111<br/>
On a 64 bit computer, 9223372036854775807 (2^63) is the max signed integer size<br/>
Binary: &nbsp;&nbsp;1000000000000000000000000000000000000000000000000000000000000000<br/>

<br/>
Therefor, (dec)9223372036854775807 vs 2147483648.<br/>
Meaning, 32-bit architectures can allocate maximum: 4294.9673MBs RAM. (In Precision)<br/>
Meaning, 64-bit architectures can allocate maximum: 8589934592MBs RAM. (In Precision)<br/>
<br/>
This means on a 64-bit operating system, you will be able to allocate much more memory, <br/>
assign more registers to CPU and userland software. What does this mean for performance?<br/>
<br/>
The simple answer: It doesn't. Atleast for the average user, or heavy gamer it will mean<br/>
they are sacrificing portability and compatibility for, extra registers. 16-bit software<br/>
will not be able to run.</font></small>
