IBM announced the POWER6™ microprocessor chip on May 21, 2007. It is a 64-bit dual-core microprocessor with 790 million transistors. The microprocessor can operate at a speed of 4.7 GHz, and it is currently the fastest microprocessor chip available. It provides twice the performance of the IBM POWER5™ microprocessor without increasing energy consumption. It is designed to be energy efficient and has enhanced reliability and virtualization capabilities. Many of the features of the chip are described in the nine papers included in this issue of the Journal.
