The max network speed in thunderbolt 4 net?

[Jia_lao]

Can I get real  40Gbps network speed ?

If I link directly by thunderbolt4 port with two NUCs , just file share or ip communication, don't use other device like display , USB, etc...

Jia_lao, Thank you for posting in the Intel® Communities Support.

In reference to your question, according to the link below, you should be able to reach 40Gbps of network speed when using Intel® Thunderbolt 3 or 4:

You will find further details about Intel® Thunderbolt here as well:

Still, we will do further research on this subject to confirm that information. As soon as I get any updates I will post tall the details on this thread.

Jia_lao, I just received an update on this matter.

After checking the case we can confirm that yes, the Intel® NUC should be able to reach 40Gbps network speed if the adapter being used supports that speed.

Here you have the link for the Intel® Compatibility Tool where you might find different cables that support that speed, tested and validated by Intel®:
