EGPU in a usb type C 3.1 gen 1
i am looking in my computer specs, and it says that it has a usb type c 3.1 gen 1, is that enough to buy an Egpu working as expected? dont know if 3.1 gen 1 counts as a thunderbolt 3, looking to put a rtx 1660ti or a rtx 2060

That would be 5 Gigabit.
Thunderbolt 3 has at least 10 Gigabit or twice as fast.

One PCIe 3.0/3.1 lane has 8Gigabit.
So, one of your USB ports is slower than even a PCIe 1x slot.
Thunderbolt 3 is at minimum as fast as PCIe 1x slot and in a perfect case fast enough for PCIe 4x

Videocards prefer to have at least PCIe 8x.

So, whatever you connect through that will be bottlenecked, hard.

Not to mention whenever people try the whole eGPU thing; those have a nasty high rate of incompatibility. Being able to power and plug something up, doesn't mean it'll work.

You might as well just make a PC instead if you're going to buy a GPU and PSU to power it.

The USB 3.1 has to specifically support "display output capable". Many laptops simply do not support that.

those adapters were designed for mining, tasks that do not need much pci bandwidth, to keep the gpu at full load
