RTX 4090 loses 20% performance when used as an external graphics card

Now connecting an external video card to certain laptop models with support for this feature takes only a few seconds and requires the user to have exactly one fairly thin wire compatible with Thunderbolt 3/4 or USB 4. A full-fledged desktop video card is installed in a separate unit with its own power supply for it, and then communicates with the laptop through the mentioned wire. Conveniently? Definitely, but what about performance?


Most “assemblies” with external graphics cards include mid-range graphics, which allows them to actually work at the limit of their capabilities, but what if you use NVIDIA GeForce RTX 4090 for these purposes? This will result in a performance loss of 8 to 28 percent, according to tests in 3DMark by¬†OmegaMalkior from the eGPU portal.
