Peripheral Component Interconnect

(PCI) Technology

The Power Macintosh 4400 offers peripheral component interconnect (PCI) expansion. Because the PCI bus is an industry standard, most existing PCI 2.0-compliant cards (with the addition of a Macintosh OS-specific software driver) will work in these computers.

PCI offers significantly higher performance than the NuBus architecture used in previous Macintosh models. Running at 33 MHz, the PCI bus is up to three times faster than NuBus, offering overall enhanced system performance, particularly in the areas of video and networking.

PCI expansion cards are mounted horizontally in an adapter card.
