Northbridge on the 1155s?

There is no northbridge on the 1155 mobos because the memory controller is in the CPU, right? And does it still have a southbridge, or are they using something else for I/O control?

For some reason Intel stopped using the term un-core, instead in Sandy Bridge it’s called the System Agent.

The System Agent houses the traditional North Bridge in the cpu.

Intel P67 chipset as south bridge.
