The IBM POWER6 processor is a dual-core, 341 mm (2); 790 million transistor chips fabricated using IBM's 65 nm partially-depleted SOI process. Capable of running at frequencies up to 5GHz in high performance applications, it can also operate under 100W for power-sensitive applications. Traditional power-intensive and deep-pipelining techniques used in high frequency design were abandoned in favor of more power efficient circuit design methodologies. The complexity and size of POWER6, together with its high operating frequency, presented a number of significant challenges for its multi-site team to complete the design on an aggressive schedule.
