Review summary
Editors' note: Apple recently updated its Power Mac G5 line, which now has three dual-processor configurations with speeds up to 2.5GHz. We hope to bring you updated performance results for the new 2.5GHz dual-processor model and news about the other technology and features improvements. Check back here soon. (6/11/04)
Although Mac and PC camps will probably never resolve their claims of having the 'fastest personal computer,' the Power Mac G5 is nonetheless an epochal leap for Apple, as it addresses G4 shortcomings such as lack of CPU speed, choked bus architecture, and tired case design. The 1.6GHz, single-processor base model starts at $1,999 and ramps up to $2,999 for a 2GHz dual-processor model with plenty of extras. We tested the dual-processor G5 with added memory totaling 2GB, upgraded graphics in the form of ATI's Radeon 9800 Pro card, and Apple's stunning 20-inch Cinema Display, which, among other extras, brings the total system price to a whopping $5,926. For the quality, the included software, and the flexibility of a Unix-based desktop that can do much of what a $20,000 Sun workstation can do, however, the Power Mac G5 is worth every penny for power users and creative professionals. And iMac fans looking for a jolt will find lots to like in the single-processor G5 models.

As car design has moved from the jelly-bean Taurus to the sharp creases of the new Cadillacs, the Power Mac G5 changes from the molded plastic of the Power Mac G3 and G4 to the industrial and machined idioms of recent PowerBooks, with a squared-off, brushed-aluminum case. Some may not like its cold, serverlike appearance, but we appreciate its clean lines and functional design.

The face of the G5 looks relatively nondescript, with only an optical-drive door, a power switch, and (finally) headphone, USB 2.0, and FireWire 400 jacks interrupting an expanse of perforated metal. Holes on the front and back maximize the cooling airflow, as the G5 processor (IBM's PowerPC 970) runs hotter than Motorola's G4. Inside, the OS monitors nine fans according to temperatures in four thermal zones, minimizing fan activity to keep the G5 one of the quietest Macs in recent memory.

A side panel pops off at the flip of a latch on the G5's back. Under a clear plastic panel, most of the G5's internals are easily accessible, making swapping RAM and the video card a snap. There's no place for a second optical drive, however, and there are limited options for a second hard drive, with only one open internal drive bay.

The rear hosts the output for the AGP slot and three PCI-X slots, which offer faster speeds of 133MHz (one slot) and 100MHz (two slots) when compared with PCI's top speed of 66MHz. In addition, you'll find ports for FireWire 800, FireWire 400, USB 2.0 (two), Ethernet, RJ-11, analog audio in and out, optical digital audio in and out, as well as jacks for external Bluetooth and AirPort antennae.

This isn't your old Power Mac. In addition to its new processors, the Power Mac G5 sports an entirely new infrastructure that does almost as much to boost system performance as the processors themselves.

The G5's processors aren't chopped liver, make no mistake. Each 64-bit chip supports fully and has two double-precision , although you won't see the benefits of 64-bit capability until software developers recompile applications. Even then, the major benefit will be the ability to address larger memory spaces, not speed. Like the AMD's Athlon 64 chip (and unlike Intel's 64-bit Itanium, which requires a 32-bit emulator mode), the G5 processor runs all existing 32-bit applications natively. As a result, the G5 is well suited for heavy scientific and database work, which can make real use of all 64 bits.

And where narrow memory and system buses hampered the G4, the Power Mac G5 features a dedicated frontside bus for each chip, running up to 1GHz, and a 400MHz, 128-bit memory bus. Apple also chose to use to connect the input and output subsystems to the system controller. What this adds up to is a more efficient system with, Apple claims, a maximum bandwidth of 8GB per second.

Our test system came equipped with 2GB of DDR400 128-bit SDRAM (up from the standard 512MB allotment), a roomy 160GB Serial ATA hard drive, and ATI's 128MB Radeon 9800 Pro graphics card. With only one 5.25-inch drive bay, Apple chose wisely by including its SuperDrive--Apple's designation for a combination DVD-R/CD-RW drive. Both the slimline Apple Pro Keyboard and the one-button Pro Mouse that came bundled with our test system worked well and had a solid and sure feel, though touch typists may not like the function keys' close proximity to the rest of the keyboard.

Our system also came with Apple's 20-inch Cinema Display, which is one of the best on the market and is priced accordingly. Thankfully, our G5 test system's nearly $6,000 price includes a speaker set. Although we expected to see a 5.1 set, the bundled 2.1 JBL Creature speakers offer surprisingly full sound for such a small set. It's worth noting that the G5's internal speaker, while no match for an external set, is an improvement over past models in terms of volume and sound quality. Lastly, our G5 test system came equipped with added-cost wireless options: the 802.11g AirPort Extreme card and a Bluetooth module for any and all devices you may have based on that wireless standard.

Though the Power Mac line doesn't ship with the same productivity software that comes with the consumer iMac (AppleWorks and others), it does include full versions of Apple's own iApps, including iTunes, iCal, iMovie, iDVD, iChat, and iPhoto. You'll also get a number of powerful, Unix-based tools for network administration and programming. Our test model came with Mac OS X 10.2.7; Apple couldn't point to a specific date but did tell us that the Power Mac G5 will ship with Mac OS X 10.3 Panther very soon. If you bought a G5 prior to Panther's launch, you can upgrade to Panther for $19.95.

Application performance
Like AMD with its Athlon 64, Apple has introduced a 64-bit processor into its next-generation desktops. In fact, Apple was first on the scene with the PowerPC G5 that it jointly developed with IBM. We tested the high-end Power Mac G5, which boasts dual 2GHz G5 processors, a 1GHz frontside bus, and onboard Serial ATA. As with the Athlon 64, the Power Mac G5 will not reach its full potential until Apple releases a 64-bit OS. With native support for today's 32-bit apps, however, and the new frontside bus architecture, plus support for 400MHz DDR SDRAM, the Power Mac G5 turned in excellent benchmark scores, offering the dramatic boost in performance that audio, video, and graphics professionals have been craving.

The Apple Power Mac G5 has several multipurpose ports that can function as interfaces for a wide variety of computer peripherals. With a dual-core processor and space for an extra hard drive, these personal computers can meet your needs with an efficient and sleek design that features easy access to the internal components. These models come standard with version 10.2 of Mac OS X.

This product features a powerful dual-core 2 GHz PowerPC G5 processor, capable of handling several programs while maintaining high processing speed. Other features of this personal computer will include:

• This computer features a 160 GB 7200 rpm hard drive and includes space for another hard drive to be inserted into the machine.
• Ports. There are several different ports available for your use, including a FireWire 800 port and two FireWire 400 ports, as well as three USB 2.0 ports and two USB 1.1 ports that are stationed on the keyboard for your convenience.
• Mac OS X. These desktop computers run version 10.2 of Apple's OS X operating system, which is also nicknamed 'Jaguar.'
• An optical drive. In addition to the dual hard drive bays, these computers have a third bay with a SuperDrive optical drive that can read both CDs and DVDs and that can burn data onto CDs.

Replacing RAM in a computer is a simple process, which most people can do in a couple of minutes with little to no prior experience. The first step in the process is to make sure that the unit is completely powered off and unplugged. Let the casing cool down for at least 10 minutes. Release the side of the case to gain access to the internal components using the latch on the backside of the unit.

Remove the air deflector and the fan assembly, and then locate the memory module on the circuit board of the desktop. Push the ejector pins on the RAM module. This should release the memory chips so they can be removed safely. Take the new memory chips and click them into place in the module, making sure to line up the notch on the DIMM and the gap on the RAM module to enable functioning of the memory.
