dp 1.4 is 25.92 Gbit/s
pci-e 3.0 x4 is 31,504 Gbit/s
25.92 x 2 + 31,504 = 83,344 Gbit/s
2 x 40 Gbit/s Thunderbolt is almost enough for the incomming max bandwidth.

From ASUS' own site:
"40 Gbps bi-directional bandwidth for superfast data transfers and video output"
Not sure how "bi-directional bandwidth" relates to video OUTPUT....

PCI-E 3.0 (x4) is saturating just under 4 gigabytes of bandwidth
ASUS's card can handle about 5 gigabytes approx total
It requires an ASUS-specific motherboard to achieve this
To qualify that it utilizes the USB 2.0 headers for additional data flow and an ASUS-specific TB header cable.
This fills in that additional leftover 1 gigabyte of data "gap" if you want to call it that.
Bi-directional doesn't mean 10 gigabytes of data transfer total
I'd assume if using both TB4 ports there'd be load balancing involved
I'm using bytes not bits
Bear in mind the 3.0 bus can handle more than the previously known theoretical limit but those locks were maintained by most vendors given timing issues with the lanes and that also is dependant on the CPU - that could also have to do with that TB header/cable being needed for timing - possible something here maybe not - who knows. Maybe they're overclocking the bus and using dedicated hardware for timing. Either way, I think it seems ... shoddy & find it unusual it's advertised as "Intel certified" it looks like "suspect" advertising to me. If anything a component that may be "Intel certified" combined with a series of ones that possibly aren't...

Isn't 3.0 x 4 a bandwidth of 32Gbps? how does it support 2 port of 40Gbps each?
What am i missing here?
