Is your Steam Deck not fast? So you can connect the graphics of your PC

How will it be possible to connect the Steam Deck to a graphics card? Or vice versa, how to connect any graphics card to a Steam Deck? It’s not exactly an exercise in technique, but it’s quite plausible for any user who has the skills and the minimum knowledge on the subject. Does this improve performance? Or instead, does it worsen the gaming experience?

Steam Deck and the graphics of your PC, how is it possible?

Many questions raised and few answers, but concise. As we know, the Steam Deck comes with an AMD APU, so it curiously lacks a Thunderbolt port that would allow, with a simple cable and an adapter or external box, to connect our GPU in a simple and colorful way, said console with the graphics card of our PC and with this we would increase performance in just 5 minutes.

By exclusively having a USB-C interface, this option is ruled out for not implementing said video and energy interface as such, so the option to achieve what we are discussing only goes through one: remove the M.2 SSD connected to the interface PCIe 3.0 x4 and plug our GPU there through a specific adapter that integrates a PCB with the PCIe 3.0 x16 connector (or 4.0 if it counts, although it will be useless due to the restrictions of the bus and its lines) and where our graphics will be connected.

But there is an obvious problem, if we remove the SSD, how do we load the console OS? Well, you have to resort to ingenuity and launch it from a microSD so that we can close the circle and enjoy better performance, right?

An RX 6900 XT boosts the performance of the AMD SoC

Nothing less than an RX 6900 XT has literally been plugged into a Steam Deck even though the interface is going to limit performance, but the experiment was worth it to understand where the bottlenecks are and how much they can squeeze the cores from SoC to gaming performance.

The data is quite interesting, since it ensures a 5.5 times increase in iGPU performance in 3DMark FireStrike with notable increases in FPS in games. To be more specific, it is reported that around 100fps in The Witcher 3 in ultra low resolution 4Kbut if we go to more current titles like Cyberpunk 2077 either elden ring at 1080p in the best possible settings we will have between 40 and 50 FPS.

Seen these data and assuming that the Steam guys have thought the same thing at the time and have tried it, knowing at the same time that the new AMD SoCs already allow usb4 For external graphics cards, will the new Steam Deck have this ability to plug in a PC graphics card to increase performance?

It would be a new kind of high-performance dock mode that would greatly improve FPS and simulate what Nintendo did with Switch, but in a brutal way and would incredibly boost the concept of a portable console.
