The computer maker has launched two systems: the four-processor PowerEdge 6950, for higher-end tasks such as housing databases, and the two-processor PowerEdge SC1435, for high-performance computing clusters or hosting Web sites. The 6950 will be sold alongside its Intel-based equivalent, the 6850, but the SC1435 replaces the Intel-based SC1425, said Jay Parker, Dell's director of worldwide marketing for PowerEdge servers.

With the move, Dell finally joins the other three major server makers in selling AMD-based x86 servers. The Round Rock, Texas-based company long had sold only Intel-based machines. However, it announced plans for AMD servers in May and began selling AMD-based PCs in September.
