Intel P55 Ibex Peak Chipset Features
Intel P55 Express chipset codenamed Ibex Peak will be able to support mainstream LGA1160 quad-core Lynnfield and dual-core Havendale with integrated GPU in Q3 2009. It is a single chip solution known as Platform Controller Hub (PCH) that has all the I/O features of the ICH. Internally, Ibex Peak with Lynnfield/Havendale is known as Summitlake. It has the ability to support dual graphics like SLI and Crossfire in x8/x8 configuration. However, the P55 chipset interconnect is still on the DMI instead of the new QPI found on the X58 chipset. For the I/O aspect, it supports 14 USB 2.0 ports, 8 PCIe 2.0 x1 ports, 6 SATA 3.0Gb/s ports, Gigabit Ethernet and IMST 9.0 with FIS port multiplier.
