Intel's next platform for enthusiasts (successor to LGA1366, X58), will consist of a 2011-pin LGA socket, the Sandy Bridge-E (enthusiast) processor that features a massive quad-channel DDR3 memory controller and 32+ lane PCI-Express 2.0 hub, and the X79 chipset. Intel is looking to skip the 6-series chipset family with its next high-end platform chipset, and perhaps it makes sense since the platform is slated for Q4 2011. The X79 is a PCH (platform controller hub), like P55 and P67, since Intel has reorganized the platform. The beefy PCI-E hub housed in the X58 northbridge is relocated to the processor die, and the southbridge is given a much needed overhaul in terms of connectivity.

The X79 is much bigger than P67 in terms of connectivity and features. Differences start right at the interconnect. While P67 connects to the processor over DMI (physical PCI-Express 2.0 x4), X79 supplements this link with an additional PCI-Express 2.0 x4 link to the processor's PCI-E hub if the user chooses so, in the EFI setup program. The chipset bus hence ends up with 8 GB/s of bandwidth, and wait till you hear what will make use of it: a 10-port SATA 6 Gb/s RAID controller integrated to the PCH! That is a huge improvement in terms of storage connectivity, which is limping with 2-port SATA 6 Gb/s (next to four 3 Gb/s ports) on 6-series chipsets.
