    VR-Zone has just published a few details on the Intel X79 chipset. To recap, this chipset will be dedicated to the Intel socket 2011 platform which will replace the current and aging X58/socket 1366 platform.

    The Sandy Bridge-Es will introduce several innovations, starting with PCI Express 3.0 support on 40 lanes as well as a quadruple channel memory controller. VR-Zone details the specifications of three SKUs which should be on sale as of September:
    • Sandy Bridge EE: 6 cores, HT, 3.3 GHz, 15 MB of L3 cache
    • Sandy Bridge E2: 6 cores, HT, 3.2 GHz, 12 MB of L3 cache
    • Sandy Bridge E1: 4 cores, HT, 3.6 GHz, 10 MB of L3 cache
    Note that the Sandy Bridge E1 is likely to be more limited in terms of overclocking even if we’re still waiting for full details on this. Note that although these specs have been confirmed, Intel is once again operating heavy segmentation.

    Looking at the X79 chipset, VR-Zone say that there will be no fewer than ten SAS compatible Serial ATA 6 Gbps ports (to recap, the Patsburg chipset is a server chipset which the X79 is derived from) and four Serial ATA 4 Gbps ports. A PCI Express 3.0 4x uplink is also reported to be dedicated exclusively to Serial ATA transfers between the chipset and the processor. USB 3.0 still hasn’t been included and motherboards will still need a dedicated USB 3.0 controller. The first X79 motherboards should be unveiled at Computex at the beginning of June. This truly high end platform will come on stream in the autumn.
