A bit random question, one which qualifies as "I'm here too long and I'm afraid to ask now" territory: what's the difference between i686 and x86_64?

How those two architectures differ?

[piinbinary]

short version: i686 is a 32bit architecture, and x86_64 is a 64 bit architecture. It adds things like larger registers (and more of them).
