==RS64== [[File:IBM RS64 Apache.png|thumb|IBM RS64 Apache]] The '''RS64''' or '''Apache''' was introduced in 1997. It was developed from "Cobra" and "Muskie" but included a more complete PowerPC ISA and was therefore set to be used in [[RS/6000]] machines as well as in AS/400 systems. It featured 128 [[Kilobyte|KB]] total on-die [[L1 cache]], 4 [[Megabyte|MB]] full speed off-chip L2 on a 128-bit bus, and a clock of 125 MHz. It scaled to a 12-processor SMP configuration in IBM's machines. RS64 was called '''A35''' in AS/400 and was one time referred to as the '''PowerPC 625''', between the defunct [[PowerPC 600#PowerPC 620|PowerPC 620]] and the PowerPC 630 (later renamed [[POWER3]]).<!-- site blocked by Wikipedia <ref>[http://www.cbronline.com/news/somerset_takes_a_powerpc_road_trip Somerset Takes A PowerPC Road Trip]</ref>--> It was manufactured with a BiCMOS fabrication process.
