High-end external GPUs still suffer a performance hit — OCuLink tests show up to a 23% drop with an RTX 4090
An external GPU (eGPU) lets you use thebest graphics cardswith slim and compact devices that lack graphics firepower. But it continues to be the case that you don’t get the full graphics card performance, due to connection limitations. OneWeibo userrecently evaluated the performance hit that you take from using the OCuLink interface. For those not in the know, OCuLink is an optical and copper link first developed for PCIe connections more than a decade ago, which has mostly been used in the server realm....
