Quad-Core G5 Processing
With two dual-core processors, at speeds up to 2.5GHz per core, the Power Mac G5 Quad doubles the punch of its dual-processor predecessor. Do the math: Quad-core processing means four Velocity Engines and eight double-precision floating-point units for blistering performance of up to 76.6 gigaflops. That means you can manipulate mountains of images or miles of footage. Crunch enormous data sets. Encode HD video or high-bit-rate audio. All at speeds you never imagined possible.
PCI Express Architecture
A modern PCI Express architecture opens up a world of high-performance expansion cards to the Mac platform. Two four-lane slots and one eight-lane slot are designed for the latest video I/O, audio DSP, and Fibre Channel expansion cards--so youll have tremendous power and productivity in a single system.(1) And with 533MHz DDR2 main memory and integrated dual Gigabit Ethernet, you can customize your Power Mac G5 for your professional workflow--even join an Xsan media network while connecting simultaneously to the Internet.
Graphics assume a new level of realism with the latest PCI Express graphics cards. Drive two Apple displays including a glorious 30-inch Apple Cinema HD Display from every Power Mac G5. Or upgrade to the NVIDIA Quadro FX 4500, the industrys fastest workstation graphics solution, for rapid-fire effects, 3D animation, and scientific stereo-in-a-window applications.(2) How much reality can you handle? Try adding up to eight all-digital Apple Cinema Displays to your Power Mac G5 and enjoy a veritable dreamscape of stunning visuals.(3)
Enormous Performance Gains
Quad-core processing dramatically accelerates performance in real-world applications. Take, for example, Adobe After Effects: The Power Mac G5 Quad renders 3D images up to 69 percent faster than the fastest dual-processor Power Mac G5 ever built.(3)
Scientists, researchers, and developers will benefit from similar performance gains. Building an Xcode project on a Power Mac G5 Quad, for example, runs 76 percent faster than on the fastest dual-2.7GHz Power Mac G5.(4)
(1) PCI Express slots are not compatible with PCI or PCI-X expansion cards.
(2) Stereo-in-a-window requires an NVIDIA Quadro FX 4500 graphics card, a CRT display, and stereo goggles (sold separately). The NVIDIA Quadro FX 4500 graphics card occupies the 16-lane PCI Express slot and adjacent PCI Express slot.
(3) To support up to eight 20-inch or 23-inch Apple Cinema Displays, install up to three additional NVIDIA GeForce 6600 graphics cards.
(4) Testing conducted by Apple in September 2005 using preproduction 2.5GHz Power Mac G5 Quad units; all other systems tested were shipping units.
The Power Mac G5 Quad is the ultimate creative platform. With two dual-core processors, at speeds up to 2.5GHz per core, the Power Mac G5 Quad doubles the punch of its dual-processor predecessor.
