if I understood right, the AMD chip is more power hungry due to not having the ultra-low-energy cores, and doesn’t support the new USB-4 standard.
Benchmarks have to wait until the actual Intel chip is out.
My 7840u can do USB4 with PCIe lanes, and that's from 2023. Of course AMD can do USB4.
The AMD board support USB4 40gbps in 2 of the 4 expansion slots.

The nice part about the Intel board is all 4 ports support usb4/thunderbolt 4 so all 4 ports are completely interchangeable whereas on the AMD board I need to remember to plug my dock into the back ports closer to the hinge.
