Rumor: AMD PCIe 3.0 chipsets will not be until 2013
According to SemiAccurate, these new chipsets from AMD, as well as current chipsets for Llano apu (A55 and A75) and Trinity (A55, A75 and A85X) will not support the PCI Express (PCIe) 3.0, so keep support the PCI Express 2.0.
Although on a practical level the lack of support pcie 3.0 bus is no problem, since in many tests the differences between the performance of PCIe 3.0 to PCIe 2.0/2.1 front are virtually nonexistent. But while the lack of PCIe 3.0 support does not affect performance, if it could affect negatively in terms of marketing at AMD platforms.
AMD has not revealed any of any APU roadmap, CPU or chipset with PCIe 3.0 support for this year, so it is presumed that probably future AMD chipsets A95X (successors of the current AMD A85X) for APU Kaveri are the first chipsets AMD PCIe 3.0 support, but come next year.
