From Barcelona to Budapest - that's the path AMD is following on its processor roadmap as it prepares to unveil three new processors this week at Computex 2008. The new CPUs are quad-core Opterons targeted at the single-socket server market. While AMD has enjoyed good success in the multi-CPU server market, it has not been much of a threat to Intel in the single-socket arena. The Budapest chips give AMD a shot at the low-end server market for enterprises and small and medium-sized businesses. The 1300-series chips will be clocked at 2.1- to 2.3 GHz and support DDR2 memory using AMD's new HyperTransport 3 technology. Current Barcelona processors use the older HyperTransport 2. Initially the CPUs will be manufactured using a 65nm process with a transition to 45nm next year. Once that transition occurs, the processors will also migrate to a new socket, AM3, and support DDR3 memory.
