The original G5 used 400 MHz RAM, which sported twice the bandwidth of the memory in the outgoing G4. In practice, these numbers meant that the Power Mac G5 ran circles around the G4, but Apple took the opportunity to improve more than just CPU performance. The G5 processor was designed was to be put into multi-processor machines, which Apple sold at the upper end of its product range. Clocked up at 2 GHz, it was the fastest 64-bit processor ever shipped, and with a 1 GHz front-side bus and support for up to 8 GB of memory out of the box, it blew away the system built around the G4. Created in partnership with IBM, it was the first 64-bit processor to be put in a personal computer.
