If you turn them into external video cards
The Oculink connector, which is used to connect an external video card, is increasingly gaining momentum on the market. It turned out that its bandwidth is not enough to fully support modern top-end video cards.
As a reminder, the bandwidth of Oculink — 64 Gbps, which is more than Thunderbolt 3/4 (40 Gbps). However, when buying an expensive video card, you need to prepare for a drop in performance.
Tests show that even for the RTX 4070 Ti Super we are talking about 10%. It's not much, but it's not a flagship 3D card either. But the RTX 4090 is already losing up to 22.6%. True, this is the result in 3DMark Time Spy using a laptop screen. When connecting an external display, the drop is less (16.6%), and in Time Spy Extreme it even drops to 5.2% in the case of the native screen and to 0% in the case of an external monitor.
Unfortunately, there are no results in the games yet. They'll probably also be highly resolution dependent, but either way, it's worth understanding that Oculink will likely be “eaten” up. performance of powerful video cards.
At the same time, Thunderbolt 5 and USB4 are on the way with bandwidths of up to 120 and 80 Gbps, respectively, so perhaps soon the problem of loss of performance of external video cards will be completely resolved.
