This MacBook Pro is powered by dual graphics processors – an NVIDIA GeForce GT 650M and an “integrated” Intel HD Graphics that shares the same system memory.
By default, this model has a pre-installed MacOS X 10.7.3 (11D2097) 2.7 GHz Intel Core i7 3820QM (Ivy Bridge) processor. This system is ideal for multimedia and graphics performance. It is actually 20% better than its predecessor. This is perfect for high-definition video transcoding and gameplay.
