I have done some reading and watched a lot of videos but none clearly answer my questions:
Does Thunderbolt 4 provide 40 Gbit of bandwidth to one or more storage devices while providing data to 2, 4k monitors at the same time? I understand that no single storage device will get more than 32Gbit.
I have noticed that some computers, such as the high end MSI Z590 boards, provide two Thunderbolt 4 ports with two DP inputs. Is it the case that one DP input will result in that signal appearing on both ports and 2 inputs will place both 4k data streams on both output ports?
Sometimes I see the word "port" being used and other times I see the word "bus". I am concerned that the 40 Gbit is a Bus limit and that this bandwidth is shared across these two ports. I presume that the 40 Gbit limit is for data on one cable leaving the host?
I am just generally interested, I do not have an application that requires these speeds. I was planning to add a Thunderbolt 3 card to an MSI Unify build and I noticed the add in card has two ports. I am now looking at the Z590 boards and noticed that some provide two ports on the rear IO panel. I just want to make sure that I understand its limitations. I do not anticipate a need for this capability but would rather have two TB4 ports than the single USB 3.2 Gen 2x2 that I see on the last generation of boards. If TB4 is operationally compatible there is nothing that I could plug into the USB 3.2 Gen 2x2 that would not work the same in the TB4 port, this enhances the attractiveness of the MSI Z590 boards. I would like to build a system that I can used for the next 5 years before my next upgrade.
Thank you for your considerations.
