VR-Zone published a quick comparison between Intel Socket B and AMD Socket AM3

We take a look at two new sockets offerings from Intel and AMD in 2008. Socket B is LGA1366 due to the integrated memory controller and AM3 is most likely still be Socket 940. The first CPU offering from Intel to be on Socket B will be Bloomfield from the Nehalem family while the first 45nm processors from AMD will be based on Socket AM3. Both Socket B and AM3 will support DDR3 1066/1333/1600 memories and interconnect technology will be CSI (Common Serial Interconnect) and Hypertransport 3.0 respectively
