For desktop APU Llano AMD propose two chip - A75 and A55. The budget motherboards for A-series processors will be based on A55 chipset. Actually, two such devices GIGABYTE - GA-A55M-S2H and GA-A55M-S2V use this chipset.
One of the main differences between AMD A55 and A75 is the absence of embedded controller interface, USB 3.0, which, of course, reduces the attractiveness of products on its base. Even less attractive GA-A55M-S2H and GA-A55M-S2V lack of SATA 6 Gb / sec ports.
In the configuration of GIGABYTE GA-A55M-S2H enter two slots for memory modules, as well as one PCI Express x16, x4, x1 and PCI. There are six slots SATA 3 Gb / s, and additional USB 2.0 ports. On the front panel there are six ports for USB 2.0, LAN port, RJ-45, S / PDIF, as well as video outputs D-Sub, HDMI and DVI.
A55M-S2V equipment roughly corresponds to GA-A55M-S2H with the only difference : the port is replaced by a PCI Express x4 PCI Express x1, and no HDMI output. Both motherboards are equipped with two BIOS and technology Ultra Durable.
