Definitely a read for those who want to know the difference.
Sixty four bit computing, has been around since the beginning of computing, but it wasn’t in the mainstream consumer marketplace until just a few years ago, while AMD announced AMD64 almost adecade ago. Getting the rest of the market to join up was aided by Intel’s own implementation called Intel® 64. From there, you needed an operating system that supported the technology and applications that were compatible to take advantage of it. Before Windows® Vista and OS X 10.6, that was hard to come by. You’ve probably seen that Windows® 7 comes in 32 and 64-bit version and wondered what the difference is. Even now, I’m still surprised at how long it’s taken to convert everyone over.
