CPU Types

CPUs Used in Silicon Graphics Computer Systems

CPU Type	Processor	Clock Speed	System/Series
IP4	R2000	8/12.5MHz 33 MHz	4D/50, 4D/70, and 4D/80 systems (Originally known as Single-Board Computer or "SBC")
IP5	R2000	16.7 MHz	4D/100 series multiprocessor systems
IP6	R2000	12.5/20 MHz	Personal IRIS (4D/20, 4D/25) systems
IP7	R3000	25/33 MHz	4D/200 series multiprocessor systems
IP9	R3000	25MHz	4D/210 series systems
