[OpenGL] Interleaving Vertices and Texture Coords and Normals

My buddy read an OpenGL book that said interleaving your vertex pointers and the corresponding texture coords etc to be next to each other in a larger array gives a speed boost.

How much of a speed boost? On which chip sets?

A: 

It just increases the data locality for the driver, potentially speeding up geometry submission.

Yeah I asked a guy who works for NVIDIA. He said it's about getting the cache to work in your favor -- essentially the same answer.
