Will a laptop eGPU work over USB 3.0 like Thunderbolt?

Question

Video cards

While looking for a laptop, I came across an interesting solution in the form of a bundle of a multimedia laptop and a desktop video card using an adapter from an mPCIe to PCIe X16 connector . mPCIe

Looking for a way to connect a PE4C V3.0 adapter to a laptop without opening it, I found another EC03 adapter that allows you to plug an ExpressCard into a USB 3.0
port www.hwtools. net/Adapter/EC03.html
As a result, you can get the following bundle:
1. The video card is installed in the PE4C V3.0 adapter
2. The PE4C V3.0 adapter is connected via ExpressCard to the corresponding slot of the EC03 adapter 3.
The EC03 adapter is connected to the USB 3.0 connector using a USB cable
and I don't consider it a fundamental difference between thunderbolt and USB 3.0.
The second question is how much the processor will influence such a bundle, and whether the video card will depend on it. If this dependence is not fundamental, then it will be possible to connect the eGPU even to a regular multimedia laptop with a Core i5 U series, but if it is dependent, then how powerful a processor is required for normal operation, for example, a GeForce GTX 760

Answer 1

Throughput USB 3.0 - 5 Gb / s. Bandwidth PCIe version 1.0 (x16) - 32/64 Gb / s. Taking into account the fact that it is data transfer that is the bottleneck of working with the GPU, garbage will come out.
