The Apple Power Macintosh G4/450 (AGP Graphics), based on the Sawtooth architecture, features a 450 MHz PowerPC 7400 (G4) processor with the AltiVec "Velocity Engine" vector processing unit and 1 MB of backside cache. It shipped configured with either 128 MB or 256 MB of RAM, a 20 GB or 27 GB Ultra ATA/66 hard drive, a 5X DVD-ROM or DVD-RAM drive, and either a 2X AGP ATI Rage 128 or Rage 128 Pro graphics card with 16 MB of SDRAM. AirPort (802.11b) was available by custom configuration.
There effectively are four different versions of this model that shipped between August 31, 1999 and July 19, 2000.
It was introduced with model number M7232LL/A (EMC 1810) on August 31, 1999 with 128 MB of RAM, a 20 GB hard drive and ATI Rage 128 graphics for US$2499.
Due to a shortage of 450 MHz PowerPC 7400 (G4) processors, on October 13, 1999, Apple infamously "speed dumped" this model -- introducing the Power Macintosh G4/400 (AGP Graphics) with the model number M7824LL/A and the same configuration and price as the 450 MHz model (differing only in speed), and introduced the M7825LL/A (EMC 1843) configuration of this model -- equipped with 256 MB of RAM, a 27 GB hard drive, a 5X DVD-RAM drive, and a higher price tag -- US$3499.
On December 2, 1999, Apple upgraded the graphics card to an ATI Rage 128 Pro -- which added a DVI port and support for 1920x1200 -- and changed the model number to M7825LL/B.
Finally, on February 16, 2000, Apple dropped the configuration back to that used by the original model (with the exception of the graphics card) -- 128 MB of RAM and a 20 GB hard drive -- reduced the price to the original (US$2499), and assigned model number M7628LL/A.
