PowerMac and PowerBook Updates?

Updates to Apple's "pro" line of computers -- the PowerMac and PowerBook -- remain two of the most anticipated hardware updates.

IBM's new PowerPC 970FX provides hope for upcoming updates for both product lines. While information on the web related to the PowerPC 970FX was relatively sparse after IBM's presentations at ISSCC last week... this Japanese report provides some basic specs with speeds ranging from 1.3GHz - 2.5GHz, and this German report offers some details of the PowerTune technology from IBM. The PowerTune technology is reportedly capable of stepping down speed to 1/2 or 1/4 of the processor's top speed, thus reducing the power consumption.

The most recent hints have pointed that PowerMacs will not be updated in February... but the new processor suggests that the new machines will top out at 2.5GHz when they do arrive.

Meanwhile, whispers have suggested that Apple is continuing to investigate liquid-based cooling techniques for both PowerMac and PowerBook lines. Whether/When this technology will be delivered as a shipping product is unclear.
