The Apple eMac G4/1.25 (USB 2.0) features a 1.25* GHz PowerPC 7447a (G4) processor with the AltiVec "Velocity Engine" vector processing unit and a 512k on chip level 2 cache, 256 MB of PC2700 DDR SDRAM, a 40 GB or 80 GB Ultra ATA/100 hard drive, a tray-loading "Combo" or "SuperDrive" optical drive, ATI Radeon 9200 graphics with 32 MB of dedicated DDR SDRAM, as well as support for AirPort Extreme and Bluetooth (neither pre-installed) in an all-in-one case with a 17.0" (16.0" viewable area) CRT display (resolution support up to 1280x960 in 24-bit color).

The eMac G4/1.25 (USB 2.0) shipped with an ice white Apple "Pro" keyboard and mouse, and boots into MacOS X 10.3 "Panther" or later (it cannot boot into MacOS 9, although it is capable of running MacOS 9 applications within the MacOS X "Classic" environment provided by MacOS X 10.4.11 and earlier).

Compared to the eMac ATI Graphics, the USB 2.0 models have USB 2.0 ports, as the name implies, but also faster processors with larger level 2 cache, a faster system bus, faster RAM, a faster ATA bus, superior graphics, and Bluetooth support.

*Please note that there also is a 1.0 GHz variant of this model that was released exclusively to education.
