9672
Launched in 1994 first as the "Parallel Transaction Server" (alongside the 9673 "Parallel Query Server"),[54] subsumed by the "Parallel Enterprise Server" launched later in the year,[55] the six generations of the IBM 9672 machines transitioned IBM's mainframes fully to CMOS microprocessors, as by a strategic decision no more ES/9000 (bipolar-based except the 9221) models would be released after 1994. The initial generations of 9672 were slower than the largest ES/9000 sold in parallel, but the fifth and sixth generations were the most powerful and capable ESA/390 machines built by IBM.[56]

In the course of the generations, CPUs added more instructions and increased performance. The first three generations (G1 to G3) focused on low cost.[58] The 4th generation was aimed at matching the performance of the last bipolar model, the 9021-9X2. It was decided to be accomplished by pursuing high clock frequencies. The G4 could reach 70% higher frequency than the G3 at silicon process parity, but it suffered a 23% IPC reduction from the G3.[58] The initial G4-based models became available in June 1997,[59] but it wasn't until the 370 MHz model RY5 (with a "Modular Cooling Unit") became available at the end of the year that a 9672 would almost match the 141 MHz model 9X2's performance.[62] At 370 MHz it was the second-highest clocked microprocessor at the time, after the Alpha 21164 of DEC. The execution units in each G4 processor are duplicated for the purpose of error detection and correction.[63] Arriving in late September 1998,[64] the G5 more than doubled the performance over any previous IBM mainframe,[60][61] and restored IBM's performance lead that had been lost to Hitachi's Skyline mainframes in 1995.[65][66] The G5 operated at up to 500 MHz, again second only to the DEC Alphas into early 1999. The G5 also added support for the IEEE 754 floating-point formats.[67][68] The thousandth G5 system shipped less than 100 days after the manufacturing began; the greatest ramping of production in S/390's history.[69] In late May 1999 the G6 arrived featuring copper interconnects, raising the frequency to 637 MHz, higher than the fastest DEC machines at the time.

In September 1996 IBM launched the S/390 Multiprise 2000, positioned below the 9672.[70][71][72] It used the same technology as the 9672 G3, but it fit half as many processors (up to five) and its off-chip caches were smaller. The 9672 G3 and the Multiprise 2000 were the last versions to support pre-XA System/370 mode. In October 1997 models of Multiprise 2000 with an 11% higher performance were launched.[73] The Multiprise 3000, based on the 9672 G5, became available in September 1999, featuring PCI buses.
