z990 was a z/Architecture-based microarchitecture designed by IBM and introduced in 2003 for their z990 processors and 2084-series mainframes. The z990 microarchitecture replaced the z900.
Process Technology[edit]
The z990 microprocessors were manufactured on IBM's 0.13 µm process with copper interconnections. This technology include silicon-on-insulator (SOI) transistors.
