AMD doesn’t work on USB 3.0 support for high end Bulldozer FX class platforms but it sure wants to make even better USB 3.0 supporting chipset for Fusion, Llano generation.
It currently ships A75 and A55 Llano chipsets, A-series chipsets, and in Q1 2012 it wants to introduce a new chipset simply called A85FX. There are two new things that will add up to A75 features. A85FX has RAID 5 and 8 SATA 6 Gb/s controllers while A75 has no RAID 5 and 6 SATA 6 Gb/s.
The rest of the spec is the same, both chipsets supports USB 3.0, four ports and as well as 10 USB 2.0 and two USB 1.1, if anyone still needs them, but they come in handy for keyboards and mice.
They also support RAID 0, 1, and 10, Displayport to VGA, PCIe X4 Gen 2 + Display Port including Crossfire support. The A85 is FM2 socket only and this socket should get introduced with Komodo platform and Trinity version of Fusion, in Q2 2012.
