Apple’s Web site has been updated with a graphic stating that the dual 1.42 GHz Power Mac G4 is “now shipping.” The high-end Power Mac (US$2,699), which was announced in January along with two others, is based on Apple’s Xserve architecture, including up to 2MB of Double Data Rate (DDR) Level 3 cache and 333 MHz DDR memory, and symmetric multiprocessing capabilities delivering 21 gigaflops (21 billion floating point operations per second) of performance. In addition, the new line features FireWire 800 and has internal support for both 54Mbps AirPort Extreme and Bluetooth wireless networking.
