The world's fastest personal computer. The new Power Mac G5 is here. It's the world's fastest*personal computer, and the first with a 64-bit processor. At its heart are two revolutionary PowerPC G5 processors, The PowerPCG chip. running at speeds up to 2GHz. And since these are The world's first64-bit processorfor personal 64-bit processors, they can access up to 8GB of computers. memory in the Power Mac G5, which is double the 4-gigabyte memory ceiling of every other PC in the world. The G5 processors also have the world's fastest frontside bus, running at 1gigahertz, which gets data to the processor almost twice as fast as the 533-megahertz SPECintrate 2000: integercalculations bus found in the next-fastest personal computer (a e dual 3.06GHz Xeon machine). In side-by-side speed tests using industry-standard SPECfp_rate 2000: Floating-point calculations DuWal llmiummalinG5 15. benchmarks,the dual 2.0-gigahertz Power Mac G5 is up to 41% faster than both the fastest Pentium 4 and dual-processor Xeon workstation. And the results Independenttests show the PowerMac G5 edges out the competition on integer get even better when using real-world applications: andblasts past them in floating-point. the new Power Mac G5 runs Photoshop more than twice as fast as the fastest PCs. Further tests reveal there are similar gains across a wide range of applications, from -- -- The PowerPCG5 chip isbased music and video to science and mathematics. Son IBM's highestperformance -' 64-bitsupercomputerprocessors. Impressed? We haven't even touched on the Power Mac G5's other features. Like its ultrahigh-bandwidth system architecture, featuring AGP 8X, PCI-X, FireWire' 800, Gigabit Ethernet, up to 500 gigabytes (yes, that's halfa terabyte) of internal Serial ATA storage and a SuperDrive" " for DVD authoring. All inside a stunning, professional-quality aluminum enclosure that features four discrete computer-controlled cooling zones for whisper-quiet operation. Together, they make the Power Mac G5 a true breakthrough in personal computing.
