It's incredibly obvious that they're trying to make Steam Deck 2 ARM-based. That's the generational change Valve is waiting for.

This is gonna be fantastic.

There are no ARM chips with enough power. They have said many times that they are not interested in minor performance improvements but rather want a leap. The Snapdragon X2 Elite chip is the leader (I cannot count Apple; they won't share their chips, obviously), but it doesn't even match AMD with their RDNA 3.5, and who knows when they will (or even if).

Taking games designed for desktop GPUs and running them on mobile GPUs with tile-based-deferred-rendering hardware will be a disaster. Mobile GPU designs will choke on modern games as they're designed around hardware features that mobile GPUs either don't have, or that run very slowly.

Peak theoretical throughput for the GPUs you find in ARM SoCs is quite good compared to the power draw, but you will not get peak throughput for workloads designed for Nvidia and AMD GPUs.

I agree they won’t do a Steam Deck 2 that’s ARM. Maybe in the future?

BUT, what about a “Steam Deck Mini”? Something at/above the current Steam Deck, maybe a little closer to Switch 2, but smaller/thinner/maybe a little cheaper?

Yeah you’re not going to run Cyberpunk 2087: Johnny’s Rent Is Due. But older games, less demanding indie games, and many emulators would still work great. Plus remote play of your big desktop if you have one.

I’m not saying they will, but I could see it as a possibility.

Apple not sharing their chips extends to Apple keeping their grip on the higher density nodes.

I wonder if it's still the case, but for a while Apple was buying the totality of TSMC's capacity for 3nm nodes, leaving the rest of the world with only 4nm+ chips to grab.

Current gen ARM is pretty strong - for an example, the switch 2 runs on ARM and it's decently more powerful than the current steam deck.

The bit about FEX is interesting. Taking x86 code and running it on ARM. The most important thing for Valve to do is pick what instruction set to use, one you can run natively or native hardware, or efficiently and reliably through translation on alien hardware. ARM might be a great choice, as hardware exists at scale on mobile devices, and emulated on other devices even if the CPU happens to be Intel or AMD. Valve is then in control, rather than Intel or Apple or Microsoft.

Why couldn’t they have an AMD GPU and an ARM CPU?

> There are no ARM chips with enough power.

Disagree.

Both Qualcomm and Mediatek have mobile SoC which are more performant than the M2 and the X2 Elite is in the ballpark of Apple top SoC.

Considering how I currently use my Steam Deck, there is nothing my current phone couldn’t do. Sure, you won’t get PS5 performance but I’m personally completely happy with Switch 2 level performance.

Do you mean there's no ARM chips that they can buy? Surely the ARM chips in Apple's devices are powerful enough aren't they?

Huh, I had not connected those (hypothetical) dots, but I could see it..

Or maybe there's 2 next-gen Steam Decks, an ultra-portable ARM-based one that's as small as can be, and a more performant x86 one with AMD's next-gen APU...

Yeah, there's a real gap in the market for a relatively compact handheld which can play low-spec PC games. The AMD-based handheld PCs available today are all pretty chunky.

jonny_eh|3 months ago

Just my thinking, they'll release a "Steam Deck Mini" that's more in line with other current ARM based gaming handhelds like the Ayn Odin.

If they did an AMD CPU using the same TSMC node that Apple uses for Arm CPUs it wouldn't be that much less power efficient and have much great compatibility.

They would realistically gain the most efficiency by getting Nvidia to design a modern super power efficient GPU like what was used in the original switch and Nvidia Shield. AMD GPUs can be great for desktop gaming but in terms of power efficiency to performance ratio Nvidia is way ahead

An AMD CPU and Nvidia GPU might be a hard thing to actually negotiate however given that AMD is big in the GPU space as well. As far as I know most "APU" aren't really that special and just a combo of GPU and CPU

You already have one, it's your phone. Winlator can run x86 games, you only need to attach a controller grip.

Why not just make a performant ARM device? Apple demonstrated to the world that it can be extremely fast and sip power.

jayd16|3 months ago

I wouldn't go that far but they are clearly poised for that, should it be adventageous.

The Frame is essentially there already, with what should be the top mobile arm setup.

If an x86 chipset dropped that fit their needs better, I don't think Valve would hesitate. I think it's just a matter of Valve trying to enable the best options down the road, whatever they may be.

Maybe, but I think it's more about the millions of ARM devices already deployed: android phones

speculating that it might be one of those arm + gpu SoC that gpu makers are currently developing, probably the amd one.

outside of gaming, i hope this work for qualcomm chips help those who bought laptops with their chips somehow. (i understand it is not the same stack but in theory)

That would make no sense, translation would use more power than the architecture difference

javier2|3 months ago

I have seen no signs there are any real GPU alternatives for ARM
