'CopprLink' destroys every eGPU standard in new test, achieves near-native-level performance with an RTX 5090 — setup requires $2,300 worth of additional hardware

An RTX 5090 plugged into this eGPU using the CopprLink standard was able to get essentially the same level of performance as the GPU directly plugged into the motherboard. The setup requires a $1,300 enclosure and a $1,000 adapter card, and it's only meant for enterprise markets, but it shows what the future of eGPUs could be for consumers.
