===80960Rx===
The 80960Rx processors were labeled as I/O Processors and included an implementation of the [[PCI Local Bus|PCI]] Bus (2.1 or 2.2 depending on the variant) as well as a 80960Jx core. These could be used on motherboards to implement on-board PCI device as well as on PCI expansion cards. The RM/RN/RS variants used a JT core with a 3x bus to core multiplication to achieve 100&nbsp;MHz internal clock speeds, while the RD variant used a JF core with 2× multiplication to achieve 66&nbsp;MHz. The RP variant had a JF core that ran at the 33&nbsp;MHz bus speed.
