The MacBook Pro “Core i7” 2.9 13-Inch (Mid-2012/USB 3.0) featured
a 22 nm “Ivy Bridge” 2.9 GHz Intel “Core i7” processor (3520M), with
two independent processor “cores” on a single silicon chip,
a 4 MB shared level 3 cache,
8 GB of 1600 MHz DDR3L SDRAM (PC3-12800) installed in pairs (two 4 GB modules),
a 128 GB Solid State Drive
an 8X DL “SuperDrive”,
an “integrated” Intel HD Graphics 4000 graphics processor that shares system memory,
an integrated 720p FaceTime HD webcam, and
an LED-backlit 13.3″ widescreen TFT active-matrix “glossy” display (1280×800 native resolution).

Connectivity includes
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 uses a “Unibody” aluminum case design
— milled from a single piece of aluminum
— and has a backlit keyboard,
a “no button” glass “inertial” multi-touch trackpad, and
a non-swappable battery design.

Compared to its predecessor, this model essentially is identical externally with the exception of the aforementioned USB 3.0 ports.

Internally, however, it has a faster processor, architecture, graphics, and RAM.
