The move toward 64-bit computing is often generalized behind the assumption that "more bits must be better," but that's not always true. In some cases, expanding support for more bits of memory addressing only results in requiring more RAM and computing overhead to do the same thing. However, Apple's progressive expansion of 64-bit support in Snow Leopard will bring performance enhancements across the board for users of new 64-bit Intel Macs. Here's a look at why, along with how it is that every version of Mac OS X since Tiger has advertised "64-bit support" as a key feature.
