NOVEMBER 16, 2005 (COMPUTERWORLD) – NEW YORK — Yesterday, I had an hour to work with Apple Computer Inc.’s new Power Mac Quad G5, and for anyone in the broadcast, sciences, music, print and photography industries, I have some advice: Place your orders now!

The latest Power Mac, unveiled last month and now shipping in limited quantities (see “Update: Apple unveils dual-core Power Mac, revised PowerBooks”), offers substantial architecture improvements over its predecessor that deliver exponential performance increases — depending on the application being used or function performed. In addition to the use of dual dual-core G5 processors, the underlying upgrades are numerous, so I’ll just list them here and then offer some commentary.

The dual-core technology now used in the $3,299 top-end Power Mac G5 puts two processors on one silicon wafer, with each processor allocated 1MB of L2 cache. The result is twice the computing power in the same space. In a dual-processor, dual-core, machine (Apple refers to it as a quad-processor machine, although others call it a dual-dual), you’ve got four processors, four 128-bit velocity engines and eight graphics processing units. The speed increase on any computing work that can be broken up into parallel processing is exponential.
