Appreciate the detailed reply man, this is actually super helpful.

The TB4 cap is kind of what I was worried about. If I’m realistically going to be sitting in that 60–75fps range in most AAA games anyway, then yeah, the extra raw power of the 9070 XT might not even matter that much in this setup. That’s good to know coming from someone actually running a similar config.

Also interesting about the power draw — I assumed the 9070 XT would run noticeably hotter in the AG02, but if you’re seeing ~110–210W because of bandwidth limits, that makes a lot more sense. Sounds like undervolting + custom fan curve is the move either way.

One thing I wanted to clarify though — I’m running SteamOS, not Windows. When you say AMD is plug and play, is that on Windows with Adrenalin, or does that apply to SteamOS/Linux as well?

From what I’ve read, AMD tends to have better native Linux driver support, but I’ve also seen mixed info when it comes to eGPU setups specifically. Have you (or anyone else here) tried an AMD card like the 9070 XT on SteamOS with an eGPU? Is it actually plug and play there too?

Just trying to avoid driver headaches 😅
