The IBM RS64 is a family of microprocessors introduced in the mid 1990s, and used in IBM's RS/6000 and AS/400 servers. These microprocessors implement the "Amazon", or "PowerPC-AS", instruction set architecture (ISA).

The IBM System p, code-named Regatta during development, [1] [2] is a high-end line of RISC /UNIX-based servers. It was the successor of the RS/6000 line, and predecessor of the IBM Power Systems server series.

The RISC System/6000 is a family of RISC-based (Reduced Instruction Set Computer-based) Unix servers, workstations and supercomputers made by IBM in the 1990s. The RS/6000 family replaced the IBM RT PC computer platform in February 1990 and is the first computer line to see the use of IBM's POWER and PowerPC based microprocessors.

Jan 24, 2011 · The RS64 line implemented the PowerPC-AS architecture and was initially released in 1997. RS64 designs were focused mainly on transaction processing and other integer intensive applications. Their floating point performance was …

The IBM RS64 family of processors is used in the RS/6000 and AS/400 server product lines. The family is optimized for commercial workloads (integer performance, large caches, branches) and does not feature the strong floating point performance of the IBM POWER family, its ancestor.

(RISC System 64) A family of RISC-based 64-bit CPUs from IBM based on the PowerPC chip family. Architected for commercial workloads rather than computation-intensive applications, the RS64...

On April 17 2001, IBM introduced the IBM pSeries 620 Model 6F1 and IBM pSeries 660 Model 6H1 to enhance the mid-range server lineup with products using many of the design elements that led to the success of the high-end pSeries Model 680.

The Power line of microprocessors has been used in IBM's RS/6000, AS/400, pSeries, iSeries, System p, System i, and Power Systems lines of servers and supercomputers. They have also been used in data storage devices and workstations by IBM and by other server manufacturers like Bull and Hitachi.

The following table compares key aspects of different IBM microprocessors.
