MacBook Pro Retina Mid-2015 15"

The MacBook Pro "Core i7" 2.5 15-Inch (Dual Graphics/Force Touch - Mid-2015 Retina Display) is powered by a 22 nm "Haswell/Crystalwell" 2.5 GHz Intel "Core i7" processor (4870HQ), containing four independent processor "cores" on one silicon chip, along with a 6 MB shared level 3 cache. It includes 16 GB of onboard 1600 MHz DDR3L SDRAM (not upgradable after purchase), 512 GB of PCIe-based flash storage, and dual graphics processors. These are an AMD Radeon R9 M370X with 2 GB of dedicated GDDR5 memory and an integrated Intel Iris 5200 Pro graphics processor with 128 MB of "Crystalwell" embedded DRAM. It also features an integrated 720p FaceTime HD webcam and a high-resolution 15.4" widescreen 2880x1800 (220 ppi) LED-backlit "Retina" display, all in a chassis weighing just under 4.5 pounds (2.04 kg). This model 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 also incorporates a backlit keyboard, an advanced "Force Touch" trackpad, a "MagSafe 2" power adapter, and an internal, sealed battery providing an Apple-estimated 9 hours of battery life.

When compared with its forerunner, this model is quite similar but boasts a faster graphics processor, quicker flash storage, a battery with higher capacity, and the more advanced "Force Touch" trackpad. It also has some different identifiers.

The Mid-2015 15-inch MacBook Pro with dual graphics is often regarded as a pinnacle of Apple's laptop design, representing the last model before the controversial shift to the Touch Bar and USB-C-only ports. It was lauded for its powerful combination of a quad-core i7 processor and the new AMD Radeon R9 M370X GPU, which offered a notable graphics performance boost. The two most significant upgrades were the much faster PCIe-based flash storage and the introduction of the innovative Force Touch trackpad. These enhancements, combined with its excellent Retina display and robust selection of legacy ports, made it an exceptionally well-rounded and reliable machine for professionals. For many, it struck the perfect balance of power, connectivity, and usability.
