Although the 1090FX will be the top tier 10-series chipset, replacing the 990FX, its North Bridge will support two PCI-Express X16 links.The 1070 provides one PCI-Express link for two graphics cards.
A leaked slide with the heading the “Chipset Competitive Landscape” has tipped up which shows that AMD wants its 10-series to go head to head against Intel’s new Ivy Bridge chipset.
AMD claims that it is better because it has more SATA connectivity and 2X16 XF. It admits that one of the disadvantages is the lack of PCI Express 3.0 and SRT. However the 10-series chipset will be compatible with current processors, which add more life to AM3+.
But the lack of PCI-Express 3.0 could be crippling for those who want to use AMD’s coming Radeon HD 7000 series graphics cards and goodness knows what else will be out next year. While PCI-Express 3.0 is probably not needed this year, it might be next year, and ironically to run a top of the range HD7000, [Oxford Comma, Ed.] you might have to buy an Intel chip.
Tom’s Hardware says that the the new SB1060 southbridge does provide an improvement over current generation motherboards and the fact that it will support an eight SATA 6 Gb/s RAID controller, all ports running at 6 Gb/s is a plus. Certainly this outpaces Intel’s 7-series in terms of SATA 6 Gb/s ports although the question is how many SATA ports you can actually eat. The SB1060 can also manage a native USB 3.0 SuperSpeed controller. Currently, the 990FX & 970 don’t support USB 3.0 but is offered through a third-party add-on.
