The revolutionary PowerPC G5 changes everything you know about personal computing. Suddenly, the next generation of high-performance applications for design and graphics, media production, and scientific research is possible and practical on the desktop. That’s because the PowerPC G5 brings a 64-bit architecture to the Mac platform—ushering in an exciting new era in personal computing.
The introduction of the PowerPC G5 is a product of Apple’s partnership with IBM, lever- aging the most advanced chip design and manufacturing expertise in the world. The results are phenomenal: 130-nanometer fabrication technology, 2GHz clock speeds, and an all-new PowerPC architecture. Together, they put enormous computing power within the reach of personal computer users:
•The ability to address huge amounts of memory provides ultrafast data access, boosting performance for 2D imaging, 3D design, and video rendering tasks.
•A high-bandwidth execution core with 12 functional units improves performance by executing multiple instructions per cycle in parallel.
•An optimized 128-bit Velocity Engine cranks through image editing tasks, high- definition video transitions, and complex scientific analysis.
•Two double-precision floating-point units accelerate 64-bit calculations for 3D visualization, research simulations, and multitrack audio creation.
The G5 processor is making its debut in the Power Mac G5, the world’s fastest personal computer according to industry-standard SPEC benchmarks.1 Now Power Mac users can tackle projects never before possible on a desktop system—and blaze through their work faster than ever. In fact, the Power Mac G5 runs Adobe Photoshop more than two times faster than the fastest Pentium 4–based system.2 Best of all, the PowerPC G5 runs 32-bit code—including existing Mac OS X applications—natively, so the transition to 64-bit power is absolutely seamless.
Welcome to the PowerPC G5, the world’s first 64-bit desktop processor and the heart of the new Power Mac.
