With third-generation Intel Core processors, Mac mini keeps up with computers twice its size. Hyper-Threading lets each core run two threads, so OS X multitasks even more efficiently. And an integrated memory controller connects fast 1600MHz memory directly to the processor, so it gets right to work on your data. In short, Mac mini is a little box of vroom. Intel HD Graphics 4000 delivers up to 65 percent more pixel-pushing performance than the previous generation of integrated graphics.
