'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

External GPUs have become increasingly common in the past few years for both laptops and handhelds in the consumer market. We have different standards like Thunderbolt and OCuLink to choose from, but the corporate world has something better: CopprLink, made by PCI-SIG itself. A new test conducted by PCWorld shows a CopprLink eGPU setup achieving essentially the same performance as an RTX 5090 GPU connected directly to the motherboard.
