Apple MacBook Pro DG "Core i7" 2.3 15" Retina Late 2013 Specs
The MacBook Pro "Core i7" 2.3 15-Inch (Dual Graphics - Late 2013 Retina Display) features a 22 nm "Haswell/Crystalwell" 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, 16 GB of onboard 1600 MHz DDR3L SDRAM (which cannotbe upgraded later), 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 "Crystalwell" embedded DRAM (and shared system memory). It also has an integrated 720p FaceTime HD webcam and a high-resolution LED-backlit 15.4" widescreen 2880x1800 (220 ppi) "Retina" display in a case that weighs just less than 4.5 pounds (2.02 kg). 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.
In addition, this model has a backlit keyboard, a "no button" glass "inertial" multi-touch trackpad, a "MagSafe 2" power adapter, and an internal, sealed battery that provides an Apple estimated 8 hours of battery life.
Compared to its predecessor, this model has effectively the same external enclosure, but it has a more efficient processor and architecture -- which results in improved battery life -- as well as faster storage, Wi-Fi, and connectivity.
