iray differs from mental ray in the following:

It is an unbiased renderer. It can use Nvidia GPUs to render, rather than just using the CPU. It uses a completely different system to mental ray to spread light through a scene. It provides near instant results, but can be slow to reduce the noise in an image to acceptable levels. With the fastest hardware, iray can produce very quick results.

mental ray and Vray are both hybrid renderers, which use a combination of tricks to produce renders, including ray tracing, final gathering, photon mapping, etc.

mental ray and Vray both have their own materials, with which they work best. iray pretty much only likes the Autodesk MIA materials.

from functional point of view - iray sets rather harsh limits to the lighting/material types you can use
vray is like mental ray only it costs you extra
