RTX 4090 Founders Edition on a External GPU Dock

External GPU Dock Wreaks Havoc on RTX 4090 Gaming Performance

Posted on

If you were thinking about installing an RTX 4090 into your shiny new external GPU box, you might want to reconsider. JarrodsTech on YouTube just released a new video showcasing what the RTX 4090 can do with an external Thunderbolt GPU dock. The results were incredibly bad. The dock crippled the 4090’s gaming performance, with most games barely being able to use 50% of its power at best.

For testing, Jarrod used two different laptops: an Asus Zenbook 14 OLED featuring a i7-1260P processor, and a beefier Aorus 17X gaming laptop equipped with a higher-performing Core i9-12900HX. Jarrod also put together a 7950X desktop test rig as a baseline, to see how much performance the 4090 retains in the external GPU dock configuration.
