Mobile Graphics Hierarchy with i3 and i5?

Hey everyone,

Has anyone seen an evaluation of the integrated graphics on the new Intel line of mobile i3 and i5 processors? Is there a good mobile graphics hierarchy chart anywhere that I can consult? I'd like to see just how they stack up to the older products/what I am familiar with.

Thanks!

(I'll be buying someone a non-gaming laptop soon and have to decide is discrete graphics are worth it...)
