June 23, 2003: The Power Mac G5 goes on sale. Affectionately nicknamed the “cheese grater” due to its distinctive perforated exterior, it’s Apple’s fastest-ever machine — and the world’s first 64-bit personal computer.
“The 64-bit revolution has begun and the personal computer will never be the same again,” Apple CEO Steve Jobs said in a press release describing the beastly machine. “The new Power Mac G5 combines the world’s first 64-bit desktop processor, the industry’s first 1 GHz front-side bus, and up to 8GB of memory to beat the fastest Pentium 4 and dual Xeon-based systems in industry-standard benchmarks and real-world professional applications.”
