The POWER1 is a multi-chip CPU developed and fabricated by IBM that implemented the POWER instruction set architecture (ISA). It was originally known as the RISC System/6000 CPU or, when in an abbreviated form, the RS/6000 CPU, before introduction of successors required the original name to be replaced with one that used the same naming scheme (POWERn) as its successors in order to differentiate it from the newer designs.

== History == The POWER1 was introduced in 1990, with the introduction of the IBM RS/6000 POWERserver servers and POWERstation workstations, which featured the POWER1 clocked at 20, 25 or 30 MHz. The POWER1 received two upgrades, one in 1991, with the introduction of the POWER1+ and in 1992, with the introduction of POWER1++. These upgraded versions were clocked higher than the original POWER1, made possible by improved semiconductor processes. The POWER1+ was clocked slightly higher than the original POWER1, at frequencies of 25, 33 and 41 MHz, while the POWER1++ took the microarchitecture to its highest frequencies — 25, 33, 41.6, 45, 50 and 62.5 MHz. In September 1993, the POWER1 and its variants was succeeded by the POWER2 (known briefly as the "RIOS2"), an evolution of the POWER1 microarchitecture.
