The Intel Core i7 has four processor cores inside of it, while the Core 2 Duo has only two cores. This means that the i7 can run multiple programs at once more efficiently than the dual core. Also, the i7 is hyper threaded, which means that the computer actually thinks it has eight cores, because two threads can be run on each core. So the i7 is even better than a Core 2 Quad, which has four cores but no hyperthreading.
