Does each Thunderbolt 4 (TB4) port have its own independent bandwidth? Is the bandwidth limited for Data?
Do the four (4) TB4 ports on my 2023 Mac mini M2 Pro share the same "total" 40Gb/s bandwidth with each other?
If each TB4 port does have its own 40Gb/s of bandwidth, would each individual TB4 port have some of its bandwidth "reserved" for DisplayPort thus limited the amount of bandwidth for Data on that TB4 port?
The following are some of the comments I have read.
TB3 is limited to 22 Gb/s, because of the overhead for DisplayPort (whether DisplayPort is being used or not).
Note: I could not have a specific example for TB4.
The amount of Data that can be transferred, over TB3 / TB4, is adjusted "on-the-fly", depending on its use.
Note: This sounds to me like the bandwidth for Data would not be limited, if DisplayPort is not being used.
The Minimum bandwidth available for Data transfer is:
(TB4) 32Gb/s (or 4000MB/s)
(TB3) 16Gb/s (or 2000MB/s)
Thank you, in advance, for your time and assistance.
