Northbridge usually implies the chip that contains the memory controler. As Nehalem has an integrated memory controler, it can be said to have an integrated northbidge as well.
Wether X58 is deserving of the title of northbridge is debatable. It's essentially just a QPI-to-PCI-E bridge chip.

Simply integrating the memory controler is responsible for most of that.
SuperPI is very latency intensive.
