I love Apple computers. And, I love the apple power macintosh G4 computer tower. It has all the guts I need in a computer. The Apple computer Power Macintosh G4/400 (PCI Graphics), based on the Yikes! architecture, features a 400 MHz PowerPC 7400 (G4) processor with the AltiVec “Velocity Engine” vector processing unit and 1 MB of backside cache. It shipped configured with 64 MB of RAM, a 10 GB Ultra ATA/33 hard drive, a 32X CD-ROM drive, and an ATI Rage 128 graphics card with 16 MB of SDRAM. Apple computers are one of the best and hottest selling brands on the market today.

Apple took computers by storm in the 80’s then lagged. Now Apple computers are on top again. Whether it is with the Apple iphone, the apple ipod, or apple notebooks, one thing for sure, the Apple Computer Brand is here to stay.

On October 13, 1999, a mere two weeks after introduction — due to Motorola’s inability to provide sufficient numbers of PowerPC 7400 (G4) processors — Apple quickly, and infamously, “reconfigured” or “speed dumped” this model — replacing it with the Power Macintosh G4/350 (PCI Graphics), and introducing the Power Macintosh G4/400 (AGP Graphics) and a revised configuration of the Power Macintosh G4/450 (AGP Graphics).

The Power Macintosh G4/400 (PCI Graphics) uses a case design effectively the same as that introduced with the Power Macintosh G3 (Blue & White) — complete with a fold down door on the side that makes upgrading very easy — but is clad in a more conservative “graphite” and white color scheme. Custom configurations also were available.

The early 400 MHz (later 350 MHz) PCI-based version used a motherboard identical to the one used in Power Macintosh G3 (Blue & White) computers (minus the ADB port), in a “graphite” colored case and with the new Motorola PowerPC 7400 (G4) CPU. The higher-speed models, code name “Sawtooth”, used a significantly changed motherboard design with AGP 2x graphics (replacing the 66 MHz PCI slot). In December 1999, the entire Power Mac G4 line was updated to the AGP motherboard.

The machines featured DVD-ROM drives as standard. The 400 MHz and 450 MHz versions had 100 MB Zip devices as conventional gear, and as an option on the 350 MHz Sawtooth. This series had a 100 MHz system bus and four PC100 SDRAM slots for up to 2 GiB of RAM (1.5 GiB under Mac OS 9). The AGP Power Macs were the first to include an AirPort slot and DVI video port.

The 500 MHz version was reintroduced on February 16, 2000, accompanied by 400 MHz and 450 MHz models. DVD-RAM and Zip drives featured on these later 450 MHz and 500 MHz versions and were an option on the 400Mhz.

Apple’s marketing name for all these early AGP models is Power Mac AGP Graphics. The code name Sawtooth was used internally before release and became the popular designation among enthusiasts.

The design was updated at the Macworld Expo New York on July 19, 2000; the new revision included dual-processor 450 MHz and 500 MHz versions, and a low-end single CPU 400 MHz model. It was also the first personal computer to include gigabit Ethernet as standard. Most people saw this revision as a stopgap release, because higher clocked G4s were not available; the G4’s Motorola XPC107 “Grackle” PCI/Memory controller prevented the G4 from hitting speeds higher than 500 MHzThe dual 500 MHz models featured DVD-RAM optical drive. Zip drives were optional on all models. These models also introduced Apple’s proprietary Apple Display Connector video port.

Apple’s marketing name for this series is the Power Mac Gigabit Ethernet. The code name was Mystic.

The Power Macintosh G4 features PowerPC 74xx (G4) processors in the wonderfully easy-to-upgrade case design introduced with the Power Macintosh G3 (Blue). The Power Macintosh G4 Cube features a unique, compact design that was not financially successful, but inspired the Mac mini series. Complete technical specifications are below.

PowerPC G4 is truly a designation applied by Apple Personal laptop or computer to describe a fourth generation of 32-bit PowerPC microprocessors. The computer company uses this name for (though closely related) processor models from Freescale, a former part of Motorola.

Macintosh computers such as the PowerBook G4 and iBook G4 laptop computers and also the Power Mac G4 and Power Mac G4 Cube desktop computers all took their name from the model. A PowerPC G4 was also utilized within the eMac, first-generation Xserves, first-generation Mac Minis, as well as the flat-panel iMac prior to the intro from the PowerPC 970.

Apple completely phased out the G4 series for desktop designs after it selected the 64-bit IBM-produced PowerPC 970 processor as the foundation for its PowerPC G5 series. The last desktop model that utilised the G4 was the Mac Mini which now comes with an Intel processor. The last portable to use the G4 was the iBook G4 but now has been replaced by the Intel-based MacBook. The PowerBook G4 has been changed by the Intel-based MacBook Pro.

The PowerPC G4 processors are also well-liked in other individual personal computer systems, including Amiga clones, like the Pegasos from Genesi. Besides desktop computers the PowerPC G4 is well-liked in embedded environments, like routers, telecom switches, imaging, media developing, avionics and military applications, where one can take advantages in the AltiVec and its SMP capabilities.

There are many power pc g4 series processors. Here is an exhuastive list of powerpc g4 processors and models that go with the processor.
