990- and 970-based
Careless distributors have leaked some info on upcoming AMD Bulldozer boards from MSI, but since we cannot verify the specs, take everything with a grain of salt.
The 990FXA-GD80 is based on the AMD 990FX chipset and SB950 southbridge. It features four DDR3 memory slots, four PCIe 2.0 x16 slots, two PCIe 2.0 slots and a lone PCI slot. It has two USB 3.0 ports, along with six USB 2.0 ports. Internally it offers two more USB 3.0 and four USB 2.0 ports, along with Firewire and six SATA 6Gbps connectors, with support for RADI 0/1/5/10.
In terms of features, the 990FXA-GD65 is quite similar, but it has just two PCIe 2.0 x16 slots, three PCIe 2.0 slots and two PCI slots.
The 970A-G45 is based on the 970 chipset and SB 950. It has two PCIe 2.0 x16 slots, two PCIe 2.0 slots and two PCI slots. Like the 990-series boards, it also packs two internal and two external USB 3.0 ports, along with a total of 12 USB 2.0 ports.
No word on pricing or availability yet, but AMD is expected to introduce Bulldozer CPUs in mid-2011.
