Thunderbolt 3.0 > PCIE 4x Alienware Amplifier?

I mean, I know the current design if pcie but the new AMD/NVIDIA architecture could support full Thunderbolt 3.0 support for laptops?

PCIE 4x is 4GB/sec
Thunderbolt 3.0 is 40GB/sec ?

This Alienware 17 amazes me, because I don't use peripherals I couldn't talk about it in reviews.  I got it for the 980M, 4k, Creative chipset, Killer NIC, 6th gen Intel, and nothing else.. but it's really loaded

I didn't even know USB type-c is gen 2 3.1 I thought it was 3.0
