目前大致歸類為三種插槽，四類處理器

Sockets
Socket 1366: 3xDDR3, External PCI Express, 1-2xQuickPath (Optional 2S?), Q408.
Socket 1160: 2xDDR3, 16xPCI Express Gen2, DMI (to southbridge, slower than FSB), 1H09.
Socket 715: No IMC, Optional PCI Express, 1xQuickPath to northbridge, 1H09.

Desktop CPUs
Bloomfield: Socket 1366, Quad-Core, Ultra-High-End.
Lynnfield: Socket 1160, Quad-Core, High-End.
Havendale: Socket 1160, MCM (CPU+GPU/IMC), Dual-Core, Mid-Range.
?Havendale?: Socket 715, Dual-Core, Low-End. Northbridges can use DDR2.

Chipsets
Socket 1366: Northbridge (PCI Express) + ICHx Southbridge (I/O).
Socket 1160: Single-Chip Southbridge (I/O) aka Ibexpeak PCH.
Socket 715: NVIDIA: Single-Chip, Intel/SiS: ???
