At work, computers get handed down all the time. Little did I know that the computer under my desk wasn’t a Power mac G5, but a Mac Pro with 2 x 2.66 Ghz Dual-Core Intel Xeon processors. Having four processors makes everything silky smooth… especially for a 64-bit operating system like Leopard. Throwback 30 years ago, that’s when only supercomputers had this kind of juice!
1976: Cray Research delivered the first Cray-1 supercomputer. This was based on a 64-bit word architecture, which formed the basis for later Cray vector supercomputers.
2006: Dual-core Montecito Itanium 2 processors in production. Sony, IBM, and Toshiba begin manufacturing of the 64-bit Cell processor for use in the PlayStation 3, servers, workstations, and other appliances. Apple, Inc. features 64-bit EM64T Xeon processors in their new Mac Pro and Intel Xserve computers, and later updates the iMac, MacBook and MacBook Pro to use EM64T Core 2 processors.
