Macbook Pro 15" Quad-Core i7 TURBO 3.7GHz GHz 16GB 512 GB SSD IG SPEC WARRANTY

Description

The MacBook Pro "Core i7" 2.5 15-Inch (Integrated Graphics/Iris Only/Force Touch - Mid-2015 Retina Display) technically is a "configure-to-order" configuration of the MacBook Pro "Core i7" 2.2 15-Inch (Integrated Graphics/Iris Only/Force Touch - Mid-2015 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 once standard MacBook Pro "Core i7" 2.5 15-Inch (Dual Graphics/Force Touch - Mid-2015 Retina Display) , which has dual graphics processors rather than just one. The MacBook Pro "Core i7" 2.5 15-Inch (Integrated Graphics/Iris Only/Force Touch - Mid-2015 Retina Display) features a 22 nm "Haswell/Crystalwell" 2.5 GHz Intel "Core i7" processor (4870HQ), 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 2880x1800 (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. This model is powered by a 22 nm, 64-bit "Fourth Generation" Intel Mobile Core i7 "Haswell/Crystalwell" (I7-4870HQ) processor which includes four independent processor "cores" on a single silicon chip. Each core has a dedicated 256k level 2 cache, shares 6 MB of level 3 cache, and has an integrated memory controller (dual channel). This system also supports "Turbo Boost 2.0" -- which "automatically increases the speed of the active cores" to improve performance when needed (up to 3.7 GHz for this model) -- and "Hyper Threading" -- which allows the system to recognize eight total "cores" or "threads" (four real and four virtual). 1 Year Warranty. Please check lid photo, it has W engraved on it permanently. However, it's fully functional and ready to serve. Battery hold charger very well despite battery service recommendation status. It's a community store, no profit intended. Original Charger and extension cable. Apple Macbook Pro Retina 15" Mid-2015 Intel i7 2.5GHz 16GB RAM 512GB SSD.
