The new 13-inch and 15-inch MacBook Pros from Apple feature faster internals than their predecessors, with the 15-inch MacBook Pro also being offered with Intel’s quad-core Skylake CPUs and AMD’s Radeon Pro GPU. The extra graphical horsepower and the extra bandwidth offered by the Thunderbolt 3.0 ports on the new MacBook Pros allow them to drive displays with insanely high resolutions.
The 15-inch MacBook Pro, thanks to its powerful Radeon Pro GPU, is able to simultaneously drive up to four 4K displays at the same time. This is in addition to the laptop’s built-in Retina Display. Alternatively, the laptop can drive two external 5K displays simultaneously. And all the displays will run at their native resolution at 60Hz, unlike the 12-inch MacBook that could only drive 4K displays at 30Hz due to bandwidth restrictions.
Since the 13-inch MacBook Pro does not come with an external AMD GPU and relies on Intel’s Iris GPU, it does not have the same graphical prowess as its bigger brother. It can drive two 4K displays at 60Hz or one 5K display at its native resolution and at 60Hz. Again, remember that the laptop is able to drive all these displays while already running its built-in Retina Display.
Since the new MacBook Pros come with four USB Type-C ports with Thunderbolt 3.0 support, you can plug the display cables in any of the ports. And if your monitor does not feature a USB Type-C port, you can use the HDMI/VGA adapter to connect the new MacBook Pro to them.
