The Opteron A1100 will be the name born by AMD's first SoC, which we knew previously as Seattle and is the first chip which will contain ARM Cortex A57 architecture working in tandem with AMDs.  It will be a full 64bit chip and will sport up to 4MB of shared L2 cache and 8MB of shared L3 cache and it will support of to four DIMMs of either DDR3 or DDR4 in dual channel with ECC.  It will boot using UEFI into a Linux environment based on Fedora and will be optimized to handle web front ends and data centre tasks.  As far as connectivity it will have 8 lanes of PCIe 3.0 and 8 SATA 3 ports. You can follow links from The Register to see the AMD Press Release.
