P.A. Semi was founded in 2003 by veterans of a number of successful chip design projects, including DEC’s Alpha and StrongARM processor families. Correctly guessing that power use would become an increasingly significant factor due to rising energy prices and an increasingly mobile world, the company designed an impressively efficient chip, the PA6T-1682M. The dual-core chip has two 64-bit, out-of-order PowerPC processors, two memory controllers, and a host of system-on-a-chip features, including PCI-E and Ethernet controllers. Thanks to an ability to aggressively shut down different parts of the chip, the 2GHz version uses only 5-13 watts.
