The MacBook Pro's integrated graphics chipset used a portion of main memory as VRAM. Though reported as 1 GB, this was actually a minimum. Actual usage varied with graphics load, resulting in slightly less RAM available for system use. A 128 MB of "Crystalwell" embedded DRAM served as both a Level 4 cache for the CPU and a cache for the integrated graphics chipset. A single 3.5mm jack could be used for analog or optical audio out, or analog audio in.

Introduced in May 2015, the MacBook Pro (Retina, 15-inch, Mid 2015) replaced the MacBook Pro (Retina, 15-inch, Mid 2014). The only changes were a faster discrete graphics chipset in the high-end model, and the inclusion of a "Force Touch" trackpad, which used haptic feedback to simulate clicks rather than a using physical button and could measure and respond to click strength. It shipped in two configurations, both with 16 GB of RAM, of which the high-end model shipped with a discrete GPU:

  • 2.2 GHz Quad-Core Intel Core i7, 16 GB of RAM, 256 GB flash storage, integrated GPU, $1999
  • 2.5 GHz Quad-Core Intel Core i7, 16 GB of RAM, 512 GB flash storage, integrated & discrete GPUs, $2499

Built-to-order options included a 2.8 GHz Quad-Core Intel Core i7 processor and flash storage of up to 1 TB.
