AMD 2012 - 2013 server roadmap

Last November AMD published server roadmap up to 2012. According to that roadmap, after current generation of "Interlagos" and "Valencia" processors the company plans to introduce "Terramar" and "Sepang" cores, built on 32nm technology. "Terramar" will be used in Opteron 6000-series products for single-, dual- and quad-processor servers, and it will have up to 20 CPU cores and require socket G2012. In addition to larger number of cores, the microprocessors will incorporate PCI-Express 3.0. Like upcoming "Interlagos" chips, Terrama will have quad-channel DDR3 memory controller. The second core, "Sepang", designated for Opteron 4000-series, will have up to 10 CPU cores, PCI-e 3.0, triple-channel DDR3 memory controller, and work in socket C2012 motherboards. In 2013, AMD will launch 6000-series "Dublin" core, and 4000-series "Macau" core:

Quad-processor "Dublin" will have up to 20 CPU cores, and will be manufactured on 28nm process, while maintaining compatibility with G2012 "Porto" platform. Single- and dual-processor "Macau", produced on 28nm technology, will have up to 10 CPU cores and will be compatible with C2012 "Luxembourg" platform. Unfortunately, it's not clear from the slide what other enhancements, besides 28nm manufacturing process, will be incorporated into new cores.
