The MacBook Pro “Core i7” 2.2 15-Inch (Integrated Graphics/Iris Only – Mid-2014 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), 500GB 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).

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.
