Fastest and most efficient processor ever. Created by Apple and IBM, after Apple ditched Motorola (A cell phone company) and callaborated with IBM to form the G5. The only current mac to have the G5 processor is the Powermac G5, and most people often refer to the powermac as just the "G5." The G5 is not exactly the most liked Mac by other Mac users, but everyone knows that it is indeed the fastest. Several nicknames for the G5 exist, these include: Cheese grater, Refrig-o-mac, PC, ugly shit. These are usually due to the fact that its not the most pretty Mac around. And its big boxy nature. The term cheese grater was formed because the front of the Powermac G5 has tiny holes, which make it look like a cheese grater.
