I have a Z790-E which has a usb 3.2 Gen 2 type-c port on the back. it is supposed
to be very fast. i have tested it and it has speed right in line with a usb2 port. the
front panel usb3 connectors are 10 time faster. i have the latest bios and all the
latest drivers. is this a hardware problem which needs an RMA or a driver issue?
Thanks.

Can you see UCMCLIENT listed in Device Manager?

If not, see this thread: https://rog.asus.com/forum/showthread.php?131960-Help-with-Device-Driver-missing-Occur-after-Z790-08...

Device Manager. where is it located? i Asussetup in the ucm folder.

Go to MoKiChu's drivers threads and grab the latest Thunderbolt drivers. They contain the UCM drivers, Asus drivers do not. It's explained in the thread link I suggested above...

Just update all relevant driver provided by MoKiChu. Also USB data transmissions also required receiving end hardware capable. Some controller on the receiving end may also cause the issue too.
