I believe many people do n’t have much purchasing power for the new Mac Pro design. The main reason is that the price is too high, but the Pro Display XDR launched at the same time is completely different, because the display is better than the computer Performance is more important. Imagine that you have the strongest computer, but only have a low color display, which is difficult to work, but there are professional displays, but the computer is slower, it can still complete the work, but it takes longer And now the latest news is that iMac Pro can't push 6K resolution when connected to Pro Display XDR.
Apple states that Pro Display XDR is compatible with the following Mac models running macOS Catalina 10.15.2 or later:
* Mac Pro with MPX module GPU (2019)
* 15-inch MacBook Pro (2018 or later)
* 16-inch MacBook Pro (2019)
* 21.5-inch iMac (2019)
* 27-inch iMac (2019)
* Any Mac model with Thunderbolt 3 port and Blackmagic eGPU or Blackmagic eGPU Pro
There is no iMac Pro, will it not work when iMac Pro is connected to Pro Display XDR? The answer is usable, but the resolution is only 5K, and the 6K resolution cannot be used, just like the wasted capacity. To promote 6K, you need the above products to cope.
So why does the 2018 version of the 15-inch MacBook Pro all promote 6K resolution, and the performance of the 21.5-inch iMac 2019 version is completely inferior to that of the iMac Pro, and both can promote 6K resolution, only the iMac Pro cannot? The reason is believed to be the CPU. Although the hardware performance is high, it is still using Intel's old "Alpine Ridge" Thunderbolt 3 controller, resulting in insufficient bandwidth for 6K resolution output.
