The Register heeft een nieuwsposting over de release van de PowerMac G4. In dit artikel claimt ome Steve dat de G4 bijna drie keer zo snel is als een PIII-600:
Jobs claimed the machine is 2.94 times faster than a 600MHz Pentium III according to data found on an Intel Web site, but Apple's product spec. more modestly credits it with being 100-200 per cent faster than the fastest PIIIs in CPU and Adobe Photoshop tests. [break] Verder nog wat specs van de G4 doos: [/break] The Power Mac G4 has 1MB of backside L2 cache running at half the speed of the processor, with a 100MHz system bus that allows a 800MBps throughput.
The built-in network is 10/100Base-T Ethernet. All three G4s have 128-bit internal memory data paths. Sensibly, the hard disks are either 10GB, 20GB or 27GB, and up to a total of 100GB is possible. The optical drives may be a 32x CD-ROM, DVD-ROM or DVD-RAM (both with video playback). There is a 100MB Zip drive, and support for two internal Ultra ATA-66 drives or three external SCSI drives (with an optional SCSI card). The graphics support consists of the ATI Rage 128 card with 16MB of SDRAM. There is support for 1600 x 1200 pixels at 32 bits per pixel and an 85Hz refresh rate.
