The IBM POWER4 is a new microprocessor organized in a system structure that includes new technology to form systems. The name POWER4 as used in this context refers not only to a chip, but also to the structure used to interconnect chips to form systems. In this paper we describe the processor microarchitecture as well as the interconnection architecture(More)
POWER5 offers significantly increased performance over previous POWER designs by incorporating simultaneous multithreading, an enhanced memory subsystem, and extensive RAS and power management support. The 276M transistor processor is implemented in 130nm silicon-on-insulator technology with 8-level of Cu metallization and operates at >1.5 GHz.
