Source is KeplerL2, who is generally considered a reliable source for insider hardware info, particularly on AMD GPU hardware and AMD SoC for consoles.
Previously I would have personally estimated Steam Deck 2 to release mid 2026-early 2027, but the recent info about an upcoming Steam Machine made me think that maybe I should push back that estimate.
Of course even if we assume this is reliable insider info, a lot can change in couple years, so things can definitely change.
I don’t think you can take a device like this and compare AAA titles on it, but even if we do then I think you can only compare it to other handhelds. Right now, checking the competitors they’re mostly on par right now for AAA performance. I stand by my other comments, if you’re looking for good graphics and good performance, a handheld is not the right device for you - you need to be looking at a desktop with an actual GPU and real power.
Those are real tradeoffs we make by going portable, we expect lower performance so we can get a longer battery life. We cannot have a long battery and great performance in a portable, they go against each other. If others are able to pull it off then yeah go with them, but every bit of performance they add means consuming more battery life.
