What is the impact of having only 2 PCIE lanes?

What does it change except having poor performance(Or being incapable at all) with external GPUs?

Thanks guys!

It's limited to 4 lanes of DisplayPort 1.2 (so 4K 60 Hz max) and 20 Gbit/s total throughput instead of 40 Gbit/s. Probably not advisable for external GPUs either.

Forgot to mention that the sole purpose of it's existence is to confuse and annoy consumers, as if they weren't confused enough already.

Oh OK, thanks! can't see myself plugging it into 2 4K screens\eGPU's anytime soon so It's a none-issue for me.

BTW, how is it different from thunderbolt 2 if it is capable of only 20 GB\S? is the USB-C connector that cause for it?

Didn't think much about that uses, I am looking to buy it and wanted to know what it changes :)

It can act as a USB 3.1 port, which Thunderbolt 2 cannot do. Also it may be able to receive power and charge the laptop through there, if the laptop supports it.
