In the second half of this year we can expect the 45nm Shanghai processor from AMD. This chip supports HyperTransport 3.0 and will have triple as much L3 cache (2MB to 6MB) and improvements to its IPC. A year later we can expect six-core Istanbul server processors, these chips will use the current Socket F1 (1207-pin) and will feature AMD's Direct Connect Architecture.
DigiTimes also has some more info about the firm's plans for 2010:
In 2010, AMD expects to introduce its third-generation AMD Opteron processor socket G34 platform, which will offer features including DDR3 memory capabilities and AMD's RD890 chipset for non-coherent HyperTransport 3.0, along with an additional HT link.
The company will also launch socket G34-based processor codenamed Sao Paolo in the first half of 2010, the processor will incorporate DDR3 memory, an additional HyperTransport 3.0 link and six-core design, while a 12-core processor codenamed Magny Cours will also leverage these features and launched in the first half of 2010.
