The MacBook Pro "Core i7" 2.3 15-Inch (Dual Graphics - Late 2013 Retina Display) features a 2.3 GHz Intel "Core i7" processor (4850HQ) with four independent processor cores on a single silicon chip, a 6 MB shared level 3 cache, and 16 GB of onboard 1600 MHz DDR3L SDRAM (which cannot be upgraded later). It includes 512 GB of PCIe-based flash storage and dual graphics processors: a NVIDIA GeForce GT 750M with 2 GB of dedicated GDDR5 memory and an integrated Intel Iris 5200 Pro graphics processor with 128 MB of embedded DRAM and shared system memory.

The device is equipped with an integrated 720p FaceTime HD webcam and a high-resolution LED-backlit 15.4" widescreen 2880x1800 "Retina" display, all in a case that weighs just less than 4.5 pounds (2.02 kg). Please note, it does not have an internal optical drive.

Connectivity includes 802.11ac Wi-Fi, Bluetooth 4.0, two USB 3.0 ports, two Thunderbolt 2 ports, an HDMI port, an audio in/out port, and an SDXC card slot.

Additionally, this model boasts a backlit keyboard, a "no button" glass multi-touch trackpad, a "MagSafe 2" power adapter, and an internal, sealed battery that provides an estimated battery life of 8 hours.

Compared to its predecessor, this model maintains the same external enclosure but features a more efficient processor and architecture, resulting in improved battery life, along with faster storage, Wi-Fi, and connectivity.
