The chaps over at vrzone got their hands on a photo of what seems to be a motherboard with AMD's upcoming Socket FM1. The photo is a reference engineering board so do not see that at all as a final production sample.
Vrzone: "AMD's test board doesn't exactly look like a retail board and it has a lot of test points for oscilloscopes and other types of test equipment. However, what we can see is that the board has native USB 3.0 support thanks to the internal USB 3.0 header so this is most like an FCH A75 based board. As it should be, it's a single chipset board, although it appears that the FCH A75 requires active cooling which is somewhat disappointing. That said, hopefully a larger passive cooler will be enough on retail boards, or at least that's what we're hoping for.
The board clearly has an HDMI, DisplayPort and D-sub connector and it should also have a pair of rear USB 3.0 ports alongside what we'd guess are four USB 2.0 ports, a Gigabit Ethernet port, six audio jacks and what appears to be a vertical eSATA connector. The slots on the board appears to be a single x16 PCI Express slot, two open ended x4 PCI Express slots, a mini PCI Express slot and a PCI slot, as well as a x1 PCI Express slot located at the centre of the board".
