The Steam Machine announcement generated massive buzz when Valve revealed its new living room console in November 2025. Digital Foundry’s hands-on coverage became their biggest video of the year. But buried in Valve’s broader hardware strategy is something potentially more significant than a single console launch. The company is quietly building infrastructure to run Steam games on ARM processors, and that could reshape PC gaming more dramatically than any individual piece of hardware.
Steam Frame Shows the ARM Vision
While the Steam Machine runs traditional x86 architecture, Valve simultaneously launched the Steam Frame, a VR headset powered by Qualcomm’s Snapdragon ARM processor. What makes this remarkable isn’t the VR capabilities but what it represents for Valve’s software strategy. The Steam Frame can run x86 Windows games on ARM hardware through Valve’s Proton compatibility layer, effectively translating games built for one processor architecture to run on completely different chips.
This isn’t theoretical future technology. According to Digital Foundry’s analysis, Valve has been testing hundreds of games through an ARM64 version of Proton. The testing data visible on SteamDB shows popular titles being verified for ARM compatibility, suggesting Valve views this as a production-ready solution rather than experimental research. The Steam Frame ships with SteamOS running on a 4nm Snapdragon chip with 16GB of RAM, and early hands-on impressions suggest games perform surprisingly well considering the translation overhead.
Everything Can Be a Steam Machine
Microsoft loves saying that everything can be an Xbox, promoting their games and services across phones, tablets, browsers, and smart TVs through cloud streaming. Valve’s strategy is fundamentally different but potentially more ambitious. Instead of streaming games from distant servers, Valve wants Steam to run natively on whatever device you’re holding, regardless of its processor architecture.
ARM support opens doors that were previously locked. Modern smartphones use ARM processors. Apple’s entire Mac lineup switched to ARM-based Apple Silicon. Qualcomm is pushing ARM chips for Windows laptops and tablets. If Valve can make Steam games run acceptably on ARM hardware through Proton, suddenly millions of devices become potential Steam Machines without Valve needing to manufacture anything.
The implications are staggering. Imagine opening Steam on your smartphone and playing actual PC games locally rather than streaming them. Picture a future where MacBooks run Steam games through native ARM translation rather than clunky virtualization. Consider ARM-powered Windows tablets transforming into gaming devices without needing x86 emulation eating battery life. Valve isn’t just building hardware. They’re building the software foundation to make Steam work everywhere.
Learning from Past Failures
Valve tried the living room console strategy before. The original Steam Machines launched in 2015 as an initiative where multiple manufacturers built gaming PCs running SteamOS. They failed spectacularly. The problem was simple: most games only ran on Windows, and developers showed zero interest in porting titles to Linux just to support a niche platform.
Proton changed everything. Instead of asking developers to port games, Valve spent seven years building compatibility layers that let Windows games run on Linux without developer involvement. The Steam Deck proved this approach worked, selling millions of units despite running Linux under the hood. Players didn’t care what operating system powered their device as long as games worked, and Proton made them work.
ARM support represents the next evolution of this philosophy. Valve learned that you can’t force developers to support new platforms, so instead you build translation technology that makes platform irrelevant. The fact that Steam Frame can run x86 Windows games on ARM hardware without developers doing anything special is the culmination of nearly a decade of work on compatibility layers.
The Technical Challenge
Running x86 games on ARM isn’t trivial. You’re translating instructions designed for Intel and AMD processors into commands that ARM chips understand, often in real-time during gameplay. This introduces performance overhead that can make games run slower than they would on native hardware. Apple solved this with Rosetta 2 for Mac, achieving surprisingly good performance for x86 apps on Apple Silicon. Microsoft’s x86 emulation on ARM Windows has been less successful, with many games struggling or simply not working.
Valve’s approach layers multiple translation steps. Proton first translates Windows API calls to Linux equivalents. Then, for ARM devices, another translation layer converts x86 instructions to ARM. The fact that games run acceptably through this double translation speaks to how much engineering Valve has invested. Digital Foundry noted that in some cases, games actually perform better through Proton on Linux than running natively on Windows handhelds, suggesting Valve’s optimization work delivers real benefits beyond just compatibility.
The Steam Frame includes hardware that helps with this translation. Its Snapdragon processor likely features performance cores designed for demanding workloads, while efficiency cores handle background tasks. Modern ARM chips have gotten dramatically more powerful, with high-end Snapdragon processors rivaling mid-range x86 chips in certain workloads. As ARM performance continues improving, the translation overhead becomes less problematic.
Why This Matters More Than Hardware
The Steam Machine itself is interesting. A fixed-spec living room PC running SteamOS that targets 4K gaming at 60fps through upscaling could appeal to players who want PC gaming without PC complexity. But it’s ultimately just another gaming box competing with PlayStation, Xbox, and high-end gaming PCs. The market has room for it, but it’s not revolutionary.
ARM support is revolutionary. If Valve succeeds in making Steam truly platform-agnostic, they unlock exponential growth opportunities. The installed base of ARM devices worldwide dwarfs x86. Billions of smartphones run ARM processors. The entire tablet market is ARM-dominated. Apple’s Mac transition to ARM Silicon created millions of potential gaming devices that currently have limited game libraries. Valve doesn’t need these devices to run games perfectly. They just need to run well enough that Steam becomes a viable gaming platform on hardware Valve doesn’t control and didn’t build.
This is where Valve’s strategy diverges most dramatically from Microsoft’s. Microsoft wants you using Xbox services, but they’re largely agnostic about what games you play through cloud streaming or Game Pass. Valve wants you buying games on Steam, and they’re building technology to ensure Steam works on whatever device you own. One model requires massive server infrastructure for cloud streaming. The other requires clever software engineering for local translation. Valve chose the path that plays to their strengths as a software company.
The Competition Heats Up
Microsoft isn’t blind to this threat. The company spent years developing x86 emulation for ARM Windows, specifically to enable gaming on devices like the Snapdragon X Elite laptops. But their approach depends on developers supporting Windows, and game compatibility remains inconsistent. Many popular titles simply don’t work through Microsoft’s emulation layer.
Valve’s advantage comes from controlling the entire stack. They dictate which games need testing, they optimize Proton specifically for gaming workloads, and they can work directly with game engines like Unreal and Unity to improve compatibility. Microsoft has to maintain broad Windows compatibility across millions of applications. Valve only cares about making Steam games work, allowing much more focused optimization.
Sony and Nintendo likely aren’t thrilled about Valve’s ambitions either. If ARM-powered smartphones can play proper PC games through Steam, that creates competition for handheld gaming devices. The Switch 2 will almost certainly use ARM architecture. If Valve gets Steam running well on ARM, there’s no technical reason a future Switch couldn’t run Steam alongside Nintendo’s store, turning it into a multi-platform gaming device rather than a closed ecosystem.
FAQs

Will Steam games run well on ARM processors?
Performance depends on the specific ARM chip and game. Translation introduces overhead that can reduce performance compared to native x86 hardware. However, modern high-end ARM processors are powerful enough that many games run acceptably, and Valve’s optimization work continues improving compatibility and performance.
What is Proton?
Proton is Valve’s compatibility layer that allows Windows games to run on Linux without requiring developer ports. It translates Windows API calls to Linux equivalents in real-time. Valve has been developing Proton for seven years, and it’s the technology that makes Steam Deck work despite running Linux.
Could Steam come to smartphones?
Technically yes, if Valve completes ARM support for Proton. Most smartphones use ARM processors, so with proper translation technology, they could theoretically run Steam games locally. However, Valve would need to navigate app store policies from Apple and Google, which both restrict competing game stores on their platforms.
Why did the original Steam Machines fail?
The 2015 Steam Machines failed because most games only ran on Windows, and developers wouldn’t port games to Linux just for a niche platform. Valve solved this by creating Proton, which lets Windows games run on Linux without developer involvement, making platform irrelevant.
What does this mean for the Steam Machine console?
The Steam Machine console is still important as a fixed-spec living room gaming device. However, ARM support represents Valve’s longer-term strategy to make Steam work on any device, potentially making individual hardware products less critical to Valve’s overall gaming ecosystem ambitions.
How does Apple’s Rosetta 2 compare?
Apple’s Rosetta 2 translates x86 Mac applications to run on Apple Silicon ARM processors with impressive performance. Valve is attempting something similar but more complex because they’re translating Windows x86 games to run on Linux ARM systems, requiring two layers of translation instead of one.
Conclusion
The Steam Machine grabbed headlines when Valve announced it, and rightfully so. A living room console running SteamOS that competes directly with PlayStation and Xbox makes for compelling news. But Digital Foundry’s analysis reveals the more interesting story hiding beneath the hardware announcements. Valve is systematically removing the barriers between Steam and any device consumers might own, regardless of operating system or processor architecture. The Steam Frame proves this strategy works in actual shipping products, not just laboratory experiments. If Valve succeeds in making ARM support mature and performant, they won’t need to convince consumers to buy specific Valve hardware. Steam will simply work on the devices people already own, from smartphones to tablets to ARM laptops to whatever computing form factors emerge in the coming years. That’s a far more ambitious vision than selling consoles, and if it works, it could make Valve’s platform more ubiquitous than even Microsoft’s cloud streaming ambitions. The Steam Machine might become remembered not as Valve’s Xbox competitor, but as the announcement that distracted everyone while Valve quietly built the infrastructure to make everything a potential Steam Machine.
