Core i3 has an integrated GPU that benchmarks just a bit faster than the GeForce 9400M in the previous Mini, but much slower than the GeForce 320M in the new Mini/MacBook/MacBook Pro 13-inch.
The MacBook Pro 15" and 17" include Core i5/i7 but have GeForce GT 330M in addition to the intel HD graphics to provide a graphics boost. It would increase the mini cost to have a second GPU.
