Gigabyte GA-P55A-UD4
 Gigabyte GA-P55A-UD4 SATA 6Gbps portsGigabyte are preparing their first motherboard that will feature native support for the latest USB and SATA specifications - USB 3.0 and SATA 6Gbps. The GA-P55A-UD4 is based on the Intel P55 chipset and is extremely similar to their current mid-range GA-P55-UD4 motherboard. They are both P55 based, socket 1156 motherboards that support up to 16GB of dual channel DDR3 over 4 slots and SLI and CrossfireX technology through the pair of PCI express x16 slots.
The board provides two USB 3.0 slots, colour coded blue on the back panel, through an NEC controller and a pair of SATA 6Gbps slots, coloured white and located next to the standard SATA ports. These run off a Marvell controller, whilst the other SATA ports run from the standard P55 PCH. The only other major chance is an upgraded CPU VRM, now using a 12+2 phase design, compared to the 8+2 phase design of the P55-UD4.
Gigabyte GA-P55A-UD4 USB 3.0 PortsThe P55A-UD4 will not replace the P55-UD4, they will exist side by side, with the P55A costing slightly more, although we're not sure how much yet. No doubt other Gigabyte boards on both the P55 and X58 chipsets, as well as other manufacturers, will begin to support the new standards soon enough. You can expect the P55A-UD4 in November or December of 2009.
