Intel this week quietly introduced four dual-core Xeon DP processors based on Dempsey architecture: 5050 (3 GHz), 5060 (3.2 GHz), 5063 (3.2 GHz) and 5080 (3.73 GHz). The 65-nm socket 771 chips run on a 1,066 MHz frontside bus, feature 4 MB of cache and dissipates 130 W (except the 95 W 5063). HyperThreading and Virtualization technologies are supported. The new Xeon DP should be eclipsed by the soon to be released Woodcrest chips based on Core architecture.
