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.
