iFixit got its hands on a brand new 15-inch MacBook and tore the machine down to its Tri-wing screws and heat sinks. The latest generation machine shares a lot of similarities with its aluminum unibody predecessors including the same case design and a similar layout of internal components. Most of the changes internally were made to the logic board components.
Besides the obvious processor and GPU differences, iFixit notes the wireless card now sports four antennas instead of a three which may improve performance. Other minor changes include the addition of a few extra heat sinks, including one for the GPU, a SuperDrive with a new model number and some modifications to the clips which hold things in place.
