The new machines also feature Xserve architecture with support for up to 2GB of Double Data Rate (DDR) memory at up to 333 MHz, the industry’s first ATI Radeon 9000 Pro graphics card and an enhanced enclosure with increased storage up to nearly half a terabyte, according to Apple.
Mac OS X 10.2 “Jaguar” will come pre-installed on all of the machines — taking advantage of “Jaguar’s” advanced UNIX-based architecture and symmetric multiprocessing capabilities, the Power Mac G4 line delivers over 18 gigaflops (18 billion floating point operations per second), and runs applications like Adobe Photoshop up to 90 percent faster than a 2.53 GHz Pentium 4-based PC, Apple said in a statement this morning.

“These new Power Macs run Adobe Photoshop faster than any PC we’ve seen,” said Bruce Chizen, president and CEO of Adobe.
Each Power Mac system has two 400Mbps FireWire ports and four 12Mbps USB ports (two on system, two on keyboard). In addition, the systems have a front headphone jack; Stereo audio line in and line out minijacks; Built-in 56K v.92 modem; and an Apple speaker minijack. Currently the v.92 modem is available on the PowerMac and the eMac — the iMac is still equppied with the v.90 modem.
Using graphics cards from Nvidia and ATI, Apple’s desktop systems feature dual display support across the product line. A single AGP 4x graphics card has both the Apple Display Connector (ADC) and a DVI connector.
