Mac rumour site Think Secret reports Apple will soon update its Power Mac G5 line, maybe even before the end of September. The reason for this revision are the poor sales of the current models, which were unveiled about six months ago. Maybe the new Power Mac G5 will be announced at next week's Apple Expo.
The April Power Mac G5 revision saw only an incremental boost in performance as the top-end model went from dual-2.5GHz processors to dual-2.7GHz. At the disappointment of many potential customers, Apple continued using the single-core PowerPC 970FX processors in the G5s and not the highly anticipated dual-core PowerPC 970MP chips, which were not ready at the time. The 970MP is said to deliver performance improvements of 50-80% in many tasks over the single-core 970FX.
According to their sources this will be the last Mac upgrade for this year. An upgrade to the Apple PowerBook lineup is expected at Macworld Expo San Francisco in January 2006, at earliest. More details at ThinkSecret.
