Product Description The MacBook Pro “Core i7” 2.2 15-Inch (Integrated Graphics/Iris Only/Force Touch – Mid-2015 Retina Display) features a 22 nm “Haswell/Crystalwell” 2.2 GHz Intel “Core i7” processor (4770HQ), 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 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 (2.04 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 new advanced “Force Touch” trackpad, a “MagSafe 2” power adapter, and an internal, sealed battery that provides an Apple estimated 9 hours of battery life. Compared to its predecessor, this model practically is identical, but it has faster flash storage, a higher capacity battery, and a more advanced “Force Touch” trackpad. It has some different identifiers, too. Intro Date: May 19, 2015 Standard Hard Drive: 256 GB SSD Int.
