Onyx2 uses the MIPS R10000 microprocessor clocked at 150, 175, 180, and 195 MHz, later increased to 250 MHz, due to a process shrink from 0.35 to 0.25 micrometers. Later 300 and 400 MHz R12000, and 500 MHz R14000 CPUs were released.
At the time of their introduction, the Onyx2 could be configured with the Reality, InfiniteReality, or InfiniteReality2 graphics subsystems. Later, the InfiniteReality2E was released and then the InfiniteReality3, in April 2000.
