It’s No Longer A Rumor: The Aluminum-Clad Power Mac G5 Is Here - [Updated]

Rumors and speculation have abounded for months, but itis finally here. At todayis Worldwide Developers Conference keynote, Steve Jobs announced what weid all been waiting for: The PowerMac G5. Sporting one or two 64-bit G5 processors running at 1.6-2.0 GHz on up to a 1GHz bus, support for up to 8GB of 400MHz DDR SDRAM, an 8X AGP Pro slot filled with a GeForceFX 5200 or a Radeon 9600 Pro, Serial ATA technology, a 4X SuperDrive and three PCI or PCI-X slots all in an all-new aluminum enclosure, the new model is a large step up from its predecessor. From Appleis press release:

Apple today unleashed the worldis fastest* personal computer ? the Power Mac G5 ? featuring the worldis first 64-bit desktop processor and the industryis first 1 GHz front-side bus. Powered by the revolutionary PowerPC G5 processor designed by IBM and Apple, the Power Mac G5 is the first personal computer to utilize 64-bit processing technology for unprecedented memory expansion (up to 8GB) and advanced 64-bit computation, while running existing 32-bit applications natively.

Delivering the industryis highest system bandwidth, the Power Mac G5 line offers dual 2.0 GHz PowerPC G5 processors, each with an independent 1 GHz front-side bus, for an astounding 16 GBps of bandwidth. The line also features the industryis highest bandwidth memory (400 MHz 128-bit DDR SDRAM with throughput up to 6.4 GBps); the industryis fastest PCI interface available on a desktop (133 MHz PCI-X); and cutting-edge AGP 8X Pro graphics capabilities, all within a stunning new professional aluminum enclosure featuring innovative computer-controlled cooling for quiet operation.

The PowerPC G5 processor is a result of the strategic relationship between Apple and IBM. At frequencies up to 2 GHz, the PowerPC G5 introduces 64-bit processing technology to desktop computing, while also running 32-bit applications natively. The PowerPC G5 processor architecture is based on a completely new execution core that features massively parallel computation for an unprecedented 215 in-flight instructions, full symmetric multi-processing, two double precision floating point units and an optimized Velocity Engine. The PowerPC G5 chips are fabricated in IBMis $3 billion state-of-the-art semiconductor facility in East Fishkill, N.Y.

The new Power Mac G5 is the worldis fastest personal computer based on SPEC CPU 2000 benchmark results and leading professional application performance tests when compared against 3.0 GHz Pentium 4-based systems and 3.06 GHz Dual Xeon-based systems:

  • In the SPEC CPU 2000 independent testing comparing the Power Mac G5 against leading 3.0 GHz Pentium 4-based systems and 3.06 GHz Dual Xeon-based systems, the Power Mac G5 won three out of four key benchmark tests. All tests were run with the same industry standard GCC 3.3 compiler to insure a fair comparison;
  • Single processor tests results show the Power Mac G5 an impressive 21 percent faster than the 3.0 GHz Pentium 4-based PC on SPECfp_base2000, which measures single processor floating point performance, and 10 percent slower on SPECint_base2000, which measures single processor integer performance; and
  • Dual processor tests results, which determine the fastest personal computer since dual processor systems are faster than single processor systems, are a clean sweep with the Power Mac G5 beating the 3.06 GHz Dual Xeon workstations by an incredible 41 percent on SPECfp_rate_base2000, which measures the total floating point throughput of the system, and edging out the same system by three percent on SPECint_rate_base2000, which measures total integer computation throughput.

In addition to outperforming Pentium 4- and Dual Xeon-based systems in industry-standard benchmarks, the Power Mac G5 ran significantly faster than Pentium 4 and Dual Xeon-based systems on performance tests of the most popular applications for creative professionals:

  • On a test of 45 commonly used actions, Adobe Photoshop ran twice as fast on the Power Mac G5 than on 3.06 GHz Dual Xeon workstations;
  • Logic Audio on the Power Mac G5 can play nearly 40 percent more tracks with reverbs applied than Cubase SX running on a 3.06 GHz Dual Xeon workstation; and
  • Genentech Blast runs up to five times faster on a Power Mac G5 than on a 3.06 GHz Dual Xeon workstation.

Complementing its computational power, the Power Mac G5 provides leading-edge expansion with dual 1.5 Gbps serial ATA interfaces; the industryis fastest PCI interface available on a desktop with a 133 MHz and two 100 MHz, 64-bit PCI-X slots; and AGP 8X Pro graphics capable of supporting the power and thermal demands of high-end professional graphics cards. The Power Mac G5 comes standard with either the NVIDIA GeForceFX 5200 or the ATI Radeon 9600 Pro graphics card. As a build-to-order option for unprecedented 3D design, visualization and gaming, the Power Mac G5 line also features the ATI Radeon 9800 Pro ? a workstation-class graphics card featuring per pixel and vertex shaders, and providing an astonishing fill rate of 3 billion textured pixels/second.

The Power Mac G5 delivers industry-leading connectivity and high-performance I/O for creative professionals with Gigabit Ethernet, FireWire 800, two FireWire 400 ports, three USB 2.0 ports, dual display support, optical digital audio input and output, analog audio input and output and a headphone jack. The system also supports 54 Mbps AirPort Extreme wireless networking and is Bluetooth ready for wireless connections to a host of Bluetooth-enabled peripherals.

The Power Mac G5 features a stunning new anodized aluminum alloy enclosure, designed to meet the needs of the most demanding professionals. The new enclosure is built around four independently controlled thermal zones for advanced airflow management, with fans in each zone that are individually controlled based on a sophisticated combination of thermal and power monitoring, resulting in the Power Mac G5 running two times quieter than the previous Power Mac G4. The G5 enclosure also features an easy-to-open access panel allowing quick access to internal components for tool-less installation of memory, hard drives, optical drives or an AirPort Extreme card. Front and rear handles allow professionals to rapidly and safely move Power Mac G5s when and where they need them, and front-mounted FireWire, USB2, and headphone ports provide convenient access for popular peripherals.

The new Power Macs will begin shipping in August, with prices ranging from $1,999 for a single 1.6 GHz G5 to $2,999 for a dual 2.0 GHz G5. You can find more information about the new systems at Appleis Web site. The systems are available for order now through the Apple Store.

Also note that the previous US$1499 OS X only 1GHz Power Mac G4 has been replaced by a US1299 OS 9/X 1.25GHz Power Mac G4, with a dual 1.25GHz at $1599.
