As you would expect, the new socket 1155 processors are incompatible with socket 1156 motherboards. The new motherboards will come in H and P varieties, with the H series taking advantage of the graphics on the processor die, whereas the P series will utilize discrete graphics only. At launch, both P67 and H67 chipsets will be available, with the H61 chipset released during Q1 2011.

Despite losing the on-chip graphics with the P series, these boards will support dual PCIe lanes running at x8 speed. The PCIe lane bandwidth of the new chipset is double that of previous Intel chipsets, firstly to increase correlation with chipsets, but also to help support SATA 6 Gb/s which runs over PCIe 1x, and future movement into USB 3.0.

The P/H67 chipsets will natively support two SATA 6Gb/s ports, with the possibility of some manufacturers adding an NEC/Marvell/Etron chip to increase this to four. Four SATA 3Gb/s will be included as standard. No USB 3.0 native support is included, much to the disappointment of some consumers, but again manufacturers at their own discretion can add an chip to give a couple of ports in the back panel, or a few more through onboard headers. USB 2.0 is provided copiously, with at least 10 ports available across the range, through either the back panel or onboard headers.
