Just wondering if releasing the steam deck 2 on arm would be a huge deal. I know arm is famous for being more efficient, but would it still be better, even when using FEX?

Valve are doing the ARM experiment with the Steam Frame.

They mentioned not wanting to release a Steam Deck 2 until there was a significant performance upgrade available.

In my opinion an ARM chip with the FEX translation overhead isn't going to be it just yet, it will probably be another AMD SoC.

We don't know. Valve has said they have no plans for a Steam Deck 2 any time soon, not until they can offer whatever they consider to be a substantial enough upgrade. It's possible ARM could be a means to that end, but we don't know. FEX probably needs to make a lot more progress before they can even consider it. Maybe it will by the time Deck 2 enters the conversation. We don't know.

IMO: the steam deck is basically a Sony PlayStation 4 in a handheld format. If gamedevs would optimise their games, like they used to, we would not need a Steamdeck 2.

Unless they can make Proton performance work emulating both the windows environment layer and a different CPU arch then I'd be very surprised to see this happen.

That's exactly what they're doing on the steam frame. I guess we'll see how it works out there.

Can't know for sure. Valve probably doesn't even know. But I think it's highly likely.

What would change? Better battery life. This was a big focus on SD and SD OLED as well. It's why they were never particularly powerful, and still aren't.

Depends on how you loosely you feel about "why". Was battery life a consideration? Sure. But it wasn't really the primary consideration. Valve's current track record is that they are masters at making a product that's surprisingly workable out of scrapyard parts that they got for cheap.

Valve didn't design the Steam Deck's chip - AMD designed it for Microsoft initially before the deal fell through. Then AMD offered the chips to Valve for cheap to recoup the costs.

Likewise, Valve didn't intentionally choose the parts in the upcoming Steam Machine. Valve just bought AMD's excess stock. That's why the Steam Machine uses such an unusual and unbalanced CPU/GPU combo.

I honestly think SD2 is going to use x86, not for any particular reason, but because AMD is most likely going to have excess stock that's x86 at the time that Valve designs it
