Motorola’s G4 processor had a high-speed vector processing unit that sped certain tasks. But IBM and Motorola parted ways over the PowerPC. Adobe Photoshop pros, video editors, 3-D artists, and scientists will surely be first in line at their local Apple stores when these new Macs arrive in August.īack in the day, the PowerPC chip was a joint venture of Apple, IBM, and Motorola.

This is a changed Apple: the race to claim computer-speed supremacy is on.ĭreams of 2004’s dual-3GHz Power Mac G5s aside, this G5 crop will undoubtedly answer the prayers of professional Mac users who need to process massive amounts of data as fast as possible. Mac fans who have wondered whether Apple would ever again compete with Windows PCs can take heart. In the next 12 months, the fastest G5 chip powering a Mac will run at a mind-bending 3GHz - 50 percent faster than today’s top model. What’s more, when Steve Jobs unveiled the G5, he made a guarantee the likes of which Apple has never before offered:

The Bluetooth module’s features are built in to the system’s motherboard, so you’ve got to either opt for Bluetooth when you buy your system or use an external adapter later.

As with previous Power Macs, you can install an AirPort card later by sliding it in.
Both of them - the AirPort antenna is T-shaped, and the Bluetooth antenna is a cylinder - plug into the back of the Mac. The G5’s metallic case creates one noticeable quirk: it effectively blocks radio signals, so the G5’s optional $99 AirPort Extreme and $50 Bluetooth features are useless until you attach the included external antennas. (Apple updated the DVD Player application on these systems to support 5.1 playback.) There’s also an optical digital audio-in port for audio pros, as well as the old standby analog audio-in and -out ports.
You can now connect a stock Power Mac to a home theater system and hear 5.1-channel digital surround sound. If you think big, turn your attention to the optical digital audio-out port on the back. For people who think small, there’s a headphone jack on the front panel. In terms of audio, the G5 covers both ends of the spectrum. Again, the G5 delivers: two USB 2.0 ports live on the machine’s back side, and a third resides on the front. Our USB wish list included copious ports and the speed of USB 2.0, which is about 40 times faster than USB 1.1 (most Macs support USB 1.1).

FireWire 400? Double-check: one on the back, plus a welcome one on the front, just below the power button. Just about any port or plug we could think of has been included in the Power Mac G5. (To put those noise levels in context, a 70-square-foot office with lights, air conditioning, and a computer turned on registers at about 40 decibels.) Apple claims that the Power Mac G5 runs at 35 decibels, compared with the mirrored-drive-door G4’s 65 decibels, which created quite a ruckus. But in normal operation, this system should be acceptably quiet. If you’re doing a lot of processing work, or if you’re in a warm room, the inside of the G5 tower will definitely heat up faster, so the fans will crank up. The system is even smart enough to anticipate heat-generating work - it can increase cooling before components get a chance to warm up. The G5’s intelligent fan management varies the fans’ speed and cranks up the airflow in the appropriate zone only when things are heating up.
You might think that nine fans would make this Mac sound like a power blower (like the Xserve or the “Wind Tunnel” Power Mac G4s), but it’s much quieter. With a single thermal zone in a traditional machine, “everyone pays the price for cooling,” says Jon Rubinstein, Apple’s senior vice president of hardware engineering.
The reason? Apple knows that cooling components only while they’re in use is more efficient than cooling every component at once. Cooling is vital in the G5 - there are nine fans inside the box, which is split into four independent thermal zones.
