Apple Announces 2.5 GHz Dual G5 Power Macs

Apple announced today a long-awaited and much anticipated update to the Power Mac G5 product line. The company has announced a new lineup that includes 1.8 GHz, 2.0 GHz, and 2.5 GHz units, all with dual processors. The dual 2.5 GHz unit includes two independent 1.25 GHz front-side busses that Apple says supports data throughput up to 20 GBps. The new systems also sport a new liquid cooling system, though that is not mentioned in the press release.


We have included most of Apple’s press release. For those who don’t want to read through all the details, skip to the bottom for The Mac Observer Spin. From Apple:



Apple today unveiled its new Power Mac G5 desktop line with every model featuring dual 64-bit PowerPC G5 processors. The top model, featuring two 2.5 GHz processors, the industry’s fastest front-side bus running at 1.25 GHz per processor, and advanced liquid cooling starts at $2,999. The entry model, featuring dual 1.8 GHz processors, starts at just $1,999.


Powered by the PowerPC G5 processor, the Power Mac G5 utilizes 64-bit processing technology for memory expansion up to 8GB, and advanced 64-bit computation while running existing 32-bit applications natively. The top of the line Power Mac G5 now offers dual 2.5 GHz PowerPC G5 processors, each with an independent 1.25 GHz front-side bus for an astounding bandwidth of up to 20 GBps. All Power Mac G5 systems ship with Mac OS X version 10.3 "Panther," which in combination with the Power Mac G5 provides creative professionals and scientists with computational power never before realized on a desktop system.


The Power Mac G5 outperforms competing desktops on the market today and ran significantly faster than 3.4 GHz Pentium 4 systems on performance tests of the most popular applications for creative professionals and scientists, including:



  • On a test of 45 commonly used actions, Adobe Photoshop ran almost twice as fast on a dual 2.5 GHz Power Mac G5 than on a 3.4 GHz Pentium 4-based PC;
  • Logic Pro 6 on the dual 2.5 GHz Power Mac G5 played up to 138 more tracks with reverbs (over four times more) than with Cubase SX on a 3.4 GHz Pentium 4-based PC; and
  • Final Cut Pro HD running on a 2.5 GHz Power Mac G5 can run eight streams of 8-bit SD video versus five streams on a dual 3.06 GHz Xeon-based Avid workstation.

The Power Mac G5 line offers leading-edge expansion with dual 1.5 Gbps serial ATA interfaces, the industry’s fastest PCI-X interface technology and AGP 8X Pro graphics. The Power Mac G5 comes standard with either the NVIDIA GeForceFX 5200 Ultra or the ATI Radeon 9600 XT graphics card; the ATI Radeon 9800 XT high-performance graphics card is available as a build-to-order option for incredible 3D design, visualization and gaming. All Power Mac G5 desktops deliver industry-leading connectivity and high-performance I/O, including Gigabit Ethernet, FireWire 800 and FireWire 400 ports, three USB 2.0 ports, optical digital audio input and output, built-in support for 54 Mbps AirPort Extreme wireless networking and an optional Bluetooth module.

The Mac Observer Spin:

When Steve Jobs announced the Power Mac G5 line at the WWDC 2003 keynote, he said that his company would have 3 GHz units in a year. A claim that was repeated during the Macworld CreativePro show in New York last July, and then reiterated at the London Apple Expo show in September.


Obviously, Apple isn’t going to hit that goal. There’s been speculation that problems at IBM’s G5 fab hindered advances, but the reality is that these new 2.5 GHz units with their 1.25 GHz front-side busses will scream, once they ship.


Speaking of screaming, we are excited about the new cooling system in that we hope they make the new G5s even quieter. Apple is claiming only that "the Power Mac G5 runs two times quieter than the previous Power Mac G4 enclosure," but that is definitely good news.


We would very much liked to have seen the prices on Apple’s G5 line come down. We believe that price has been one of the factors that has kept G5 sales far below what they could have been. This is especially true on the low end where Apple has actually jacked up the price a couple of hundred dollars. Yes, you’re getting a lot for your money, but the proof is in the pudding in that G5 sales have been stagnant. Perhaps the speed boost can fix that.


That said, we are otherwise delighted with these new machines.
