New MacBooks Pro in theory could support 8K monitors, but that's not possible yet

This week iFixit took apart the new MacBooks Pro and, among the few news, it was found that the doors Thunderbolt 3 Both 13 and 15 inch models are equipped with Intel's new generation chipset, called “Titan Ridge”, which was announced earlier this year.

Basically, the Titan Ridge family chips for Thunderbolt 3 connections bring, in addition to USB-C format compatibility, interface support DisplayPort 1.4, which in turn allows you to connect the notebook to an external 8K monitor (!) and display images at a rate of 60Hz (with image compression).

The series of this chipset family that equips the new MacBooks Pro is JHL7540, which according to Intel and as above, supports DisplayPort 1.4. However, in addition to getting a compatible Thunderbolt 3 port, support for this interface also depends on the graphics card installed, which varies with MacBook Pro and leaves the 13 inch model out of the picture.

As disclosed by MacRumors, the new 13-inch TouchBook MacBook Pro supports the standard High-Bit Rate 2 (HBR2)which corresponds to DisplayPort version 1.2 which allows you to connect the device to an external 4K display and display images at 60Hz due to a limitation of the integrated Intel Iris Plus 655 GPU.

On the other hand, the 15 inch Touch Bar model supports the new protocol. High-Bit Rate 3 (HBR3), the signal standard of both DisplayPort 1.3 and 1.4. Apple says the dedicated AMD Radeon Pro graphics let you connect up to two 5K monitors at a 60Hz rate to your notebook.

So the new 15-inch MacBook Pro theoretically supports DisplayPort's 1.4 interface, but still can't control an 8K display, contrary to the promise of the new Intel chipset. This may be enabled by a future software update, but nothing is certain at this time.

This is not the only indication that even working together, Intel and Apple have not thought of the best way to equip new components. Just this week, a controversy arose around the overheating of the 15-inch model equipped with the new generation Core i9 processor from the same manufacturer, and who is to blame for that.

Still related to Thunderbolt connections, yesterday we also commented that Apple has confirmed that all Thunderbolt 3 ports on the new 13 inch MacBook Pro are equal and offer a transmission speed that can reach 40Gbps, unlike previous models where only the left ports hit such a band.
