2.3GHz Quad-core Intel Core i7, Turbo Boost up to 3.3GHz.This is by far the best computer I’ve ever owned, and the best Mac I’ve ever owned. It is only occasionally rebooted or switched off, usually every couple weeks. It is usually kept powered on and running (not in sleep mode) 24/7. Since July 2012, I have had absolutely no problems with this laptop at all. I bought mine in July 2012 from Apple, and then anxiously waited for it to arrive via UPS from China. The MacBook Pro without Retina Display is still one of the best laptops you can buy in this price range. They also added USB 3.0 connectivity, and both the 13 and 15 inch models can be configured with a 1TB hard drive or SSDs up to 512GB that are twice as fast as the previous generation MacBook Pro.
Apple updated the Intel processor and added powerful discrete graphics from NVIDIA. The latest MacBook Pro 15.4″ was released in June 2012 as an upgrade of the previous model, retaining the same design and main features.
