The MacBook Pro "Core i7" 2.9 13-Inch (Mid-2012/USB 3.0) is powered by a 22 nm "Ivy Bridge" 2.9 GHz Intel "Core i7" processor (3520M), which has two independent processor cores on a single chip and a 4 MB shared level 3 cache. It includes 8 GB of 1600 MHz DDR3L SDRAM (PC3-12800) installed in two 4 GB modules, a 750 GB Serial ATA (5400 RPM) hard drive, an 8X DL "SuperDrive," an integrated Intel HD Graphics 4000 processor that shares system memory, an integrated 720p FaceTime HD webcam, and a 13.3-inch LED-backlit widescreen TFT active-matrix "glossy" display with a native resolution of 1280x800.
Connectivity features consist of AirPort Extreme (802.11a/b/g/n), Bluetooth 4.0, Gigabit Ethernet, a Firewire "800" port, two USB 3.0 ports, a "Thunderbolt" port, audio in/out, and an SDXC card slot.
This model utilizes a "Unibody" aluminum case design—milled from a single piece of aluminum—and comes with a backlit keyboard, a "no button" glass "inertial" multi-touch trackpad, and a non-removable battery design providing an Apple-estimated 7 hours of battery life.
Compared to the previous version, this model is externally almost identical except for the addition of USB 3.0 ports. Internally, however, it boasts a faster processor, architecture, graphics, and RAM.
