One of the surprising specifics of the new fifteen-inch MacBooku Pro is that even the base model has an AMD graphics processor. Previously Apple it offered an integrated processor for basic models and reserved discrete graphics for "higher" models. The presence of AMD graphics was explained in a review by ArsTechnica. According to them, this was the only way to allow the machines to control two 5K monitors.

When to the new MacBooku Pro If you connect one of LG's 5K monitors, you may see the two images merge into one solid image. This is because DisplayPort, supported by Intel graphics, does not have enough bandwidth on its own to drive a 5K monitor at 60Hz. This could change with the arrival of DisplayPort 1.3. Apple now actually "sends" two DisplayPort 1.2 streams over a single Thunderbolt 3 cable. Intel graphics support a total of three streams. Since a single 5K monitor will use two of them, that means all of them could be used to drive the internal display and a single 5K monitor. AMD graphics, on the other hand, support six streams. This allows the XNUMX-inch MacBooku Pro use four of them to drive two 5K monitors, the fifth for the internal display, and the last remaining one theoretically for another 4K display.

A review from ArsTechnica states that Apple with this step he probably wanted to avoid confusion, with some MacBooky Pro support two 5K monitors, while others are limited to just one. Using Intel Iris graphics on the 13-inch models and AMD Radeon Pro For the 15-inch models, the whole thing has become simpler: the 13-inch models support one 5K display, while the 15-inch models without exception support two. This is also why Apple couldn't decide on faster Nvidia graphics. The laptop version of the GTX 1060, which is Nvidia's slowest laptop chip, has a thermal design power of 85W, while the AMD graphics at MacBooku  Pro 35W. And while Nvidia graphics support DisplayPort 1.3, Thunderbolt 3 drivers and most monitors only support DisplayPort 1.2.
