AMD has changed many plans and it is now saying to its investors that the new APU, Accelerated processing unit that unified the graphics chipset and a CPU in a single chip won't be out until 2H 2009.
Back in 2006 AMD claimed that it can have Fusion out in late 2008, then in pushed it back to early 2008 and all of a sudden we are talking about second half of 2009.
It won’t be a new chip to begin with, AMD will take one of the existing Stars cores developed in 45nm and a GPU core based on existing high end discrete. AMD claims that this will be the second 45 nanometre product and it will be developed by the current Silicon on insulator rules.
Griffin based Northbridge will also be the part of this chip. The graphics core inside will support DirectX and UVD but AMD haven’t disclosed what generation is the graphics inside, R6xx or R7xx.
The chip has its own memory controller, cache and a PCIe interface. It doesn’t sounds that impressive as Fusion, but I guess that this is the best that they hope that AMD can do.
