It's not. TB3 enclosures have been known to offer significantly worse performance than plugging it in directly into a desktop, and the performance difference only increases as GPUs get more and more powerful (and demand greater bandwidth). Off the top of my head, a moderately powerful GPU like the RTX3080 could see anywhere from 20% to 50% performance drop when put into an eGPU enclosure.

How does that compare to laptop dGPUs though? Which are already neutered performance-wise for heat and power consumption reasons. Both of which also get worse as you scale up to more powerful GPUs just as happens with PCIe bandwidth.
