Mid 2015 macbook pro 15 dual graphics pro#
See here and here as references, as well as the official Tech Specs. I have a MacBook Pro (Retina, 15-inch, Mid 2015) - I want to run two external 24' DisplayPort Monitors. So unless the Tech Specs provided by the seller states the Model Identifier as MacBookPro11,5 or states it has both the Intel Iris Pro Graphics and AMD Radeon R9 M370X Graphics then you'll have to ascertain additional information from the seller to determine what Graphics Adapters it has. The Mid 2015 model has two USB 3.0 ports, an HDMI port, an SDXC card slot, a MagSafe 2 port, two Thunderbolt 2 ports, Bluetooth 4.0, and 802.11ac Wi-Fi. The MacBook Pro (Retina, 15-inch, Mid 2015) with a 2.8GHz CPU and both the Intel Iris Pro Graphics and AMD Radeon R9 M370X Graphics has the Model Identifier: MacBookPro11,5 Internally, the Mid 2015 Dual Graphics (DG) model has two graphics processors: an AMD Radeon R9 M370X and an Intel Iris Pro 5200 processor. The MacBook Pro (Retina, 15-inch, Mid 2015) with a 2.8GHz CPU and only the Intel Iris Pro Graphics​ has the Model Identifier: MacBookPro11,4 MacBook Pro 15-inch Retina 2.5GHz 1TB / 16GB Dual Graphics (Mid-2015) LED-backlit 15.4 widescreen 2880x1800 (220 ppi) Retina display 2.5 GHz Intel Quad. The MacBook Pro (Retina, 15-inch, Mid 2015) with a 2.8GHz CPU was available with either an Intel Iris Pro Graphics​ only, or with the Intel Iris Pro Graphics​ and AMD Radeon R9 M370X Graphics, so you can't go by just the CPU. To answer your question " Does the 2.8GHz model come with dual Intel/AMD graphics card or just Intel embedded graphics only?", the 2.8GHz model came both ways. The MacBook Pro (Retina, 15-inch, Mid 2015) with a 2.8GHz CPU and both the Intel Iris Pro Graphics and AMD Radeon R9 M370X Graphics has the Model Identifier: MacBookPro11,5.
