The MacBook Pro “Core i7” 2.3 15-Inch (Mid-2012/USB 3.0) features a 22 nm “Ivy Bridge” 2.3 GHz Intel “Core i7” processor (3615QM), with four independent processor “cores” on a single silicon chip, a 6 MB shared level 3 cache, 416 GB of 1600 MHz DDR3L SDRAM (PC3-12800) installed in pairs (two 2 GB modules), a 480GB Solid State Drive, an 8X DL “SuperDrive”, dual graphics processors — a NVIDIA GeForce GT 650M with 512 MB of dedicated GDDR5 memory and an “integrated” Intel HD Graphics 4000 graphics processor that shares system memory, as well as an integrated 720p FaceTime HD webcam. The standard configuration of this model has an LED-backlit 15.4″ widescreen TFT active-matrix “glossy” display (1440×900 native resolution), but also was available via custom configuration with a “high-res” glossy or antiglare 1680×1050 display for an additional US$100. 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, separate audio in and out ports, 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 that provides an Apple estimated 7 hours of battery life. 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.
