AMD's chip supports 64-bit computing, ushering in a new era for desktops. But the best reason to buy the CPU is strong performance on familiar 32-bit apps.
Athlon 64 vs. Apple G5 Systems: Not Even Close (chart)
Apple Power Macs did well on Photoshop, but the 64-bit AMD-based systems won handily on most tests.

How We Test: In Adobe Premiere we timed the rendering of our workspace and timed the export of a 959-frame movie at 720 by 480 resolution and 30 frames per second into the QuickTime format. In Adobe Photoshop we timed the operation of ten filters on a 50MB image file and a 150MB file. In Microsoft Word we timed a search-and-replace of one word in a 1437-page document, and the execution of the auto summarize function on a 210-page document. We ran Quake III version 1.32's included "timedemo four" using high quality settings at two resolutions, and recorded the average frame rate. All machines were tested with 1GB of RAM and the ATI Radeon 9800 Pro graphics card; the Mac version of the graphics card has a maximum of 128MB of RAM, while the high end for PCs is 256MB. Most of the PCs used dual, RAID-striped hard drives; the Apple systems did not. We retested the Alienware Aurora with the 128MB Radeon 9800 Pro card and without RAID for more-direct comparison with the G5 systems. Tests on PCs performed by the PC World Test Center; tests on Apple systems performed by the Macworld Test Center. All rights reserved. Chart Notes: In Quake III, higher is better; elsewhere, lower is better. Best scores in bold.
