The MacBook Pro “Core i7” 2.3 15-Inch (Integrated Graphics/Iris Only – Late 2013 Retina Display) technically is a “configure-to-order” configuration of the MacBook Pro “Core i7” 2.0 15-Inch (Integrated Graphics/Iris Only – Late 2013 Retina Display), but also is documented as a separate model for reader convenience. Other than the processor, these models are identical.
Please also note that this model should not be confused with the standard MacBook Pro “Core i7” 2.3 15-Inch (Dual Graphics – Late 2013 Retina Display), which has dual graphics processors rather than just one.
The MacBook Pro “Core i7” 2.3 15-Inch (Integrated Graphics/Iris Only – 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, 8 GB of onboard 1600 MHz DDR3L SDRAM (which could be upgraded to 16 GB at the time of purchase, but cannot be upgraded later), 256 GB of PCIe-based flash storage, 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 2880×1800 (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.
