Intel's latest Socket for a processor is Socket T, or, LGA 775. LGA stands for Land Grid Aray, which means that the pins are on the Motherboard, not the Processor. The Prescott is the only processor to use the LGA 775 socket type, for now. Intel changed from Socket 478 to LGA 775 because Intel plans to offer a Front side bus of 1066 MHZs. The 'T' in Socket T is derived from the Tejas core which was going to replace the Prescott. Tejas is no longer a replacement. Problems with the massive amount of heat that would come from this processor stopped development of the Tejas core.
