Introduction: A New Era of Console-Like PC Gaming
The battle between Windows 11 and SteamOS on Valve’s Steam Machine is not simply a comparison between two operating systems. It represents a much bigger question facing the gaming industry: should the future of PC gaming look more like a traditional computer, or should it become a console-like experience built around simplicity, optimization, and convenience?
For years, Windows has dominated PC gaming because of its unmatched compatibility, massive software ecosystem, and support from nearly every major game developer. SteamOS, however, has slowly challenged that dominance by offering a lightweight Linux-based gaming environment designed around the living-room experience.
The arrival of official Windows drivers for the Steam Machine created a unique opportunity to compare both platforms on identical hardware. Many expected Windows 11 to destroy SteamOS because games technically run natively on Microsoft’s operating system while SteamOS depends on Proton, Valve’s compatibility layer that translates Windows games into Linux-compatible instructions.
However, real-world testing revealed a much more surprising result. Windows 11 wins some battles, especially in synthetic benchmarks and certain 4K scenarios, but SteamOS remains extremely competitive. In many games, the difference between the two systems is so small that it becomes almost impossible for players to notice.
This comparison reveals something important: the future of gaming performance may not be decided by raw operating system efficiency alone. Optimization, drivers, ecosystem support, and user experience may matter more than a few extra frames per second.
Windows 11 Arrives on Steam Machine, But Valve Keeps Expectations Low
Valve officially released Windows resources for the Steam Machine, allowing users to install Microsoft’s operating system on the hardware. However, Valve made it clear that Windows support is provided with limited expectations.
The company describes these resources as being provided “as is” and states that it cannot officially provide full Windows support for Steam Hardware.
Currently, Valve provides only essential drivers:
GPU support
Wi-Fi connectivity
Bluetooth
SD card reader support
Windows already handles the machine’s audio codec natively, so no dedicated audio driver was required.
However, one major limitation remains: there is no official dual-boot experience yet.
Installing Windows currently requires removing SteamOS completely. Users who later want to return to SteamOS must reinstall the operating system using Valve’s recovery image.
This makes Windows installation more complicated than simply switching between two operating systems.
Windows Installation Works, But It Requires Extra Preparation
YouTuber ETA Prime tested Windows 11 on the Steam Machine and found that installation was relatively smooth.
The major components worked correctly:
Graphics acceleration
Wireless networking
Bluetooth
Video playback
However, there is an important detail: the test system was not completely stock.
The original Steam Machine configuration includes:
16GB RAM
Single-channel memory configuration
ETA Prime upgraded the machine to:
64GB RAM
5,600 MT/s dual-channel memory
Both Windows and SteamOS testing used this upgraded configuration, meaning the comparison between operating systems was fair.
However, buyers should remember that retail Steam Machines may deliver slightly different results.
Steam Machine Hardware: Small Size, Serious Performance
The Steam Machine uses a semi-custom AMD processor designed specifically for Valve’s compact gaming system.
The hardware includes:
CPU Specifications
AMD Zen 4 architecture
6 cores
12 threads
Boost clock up to 4.85GHz
Approximately 28-30W power consumption
Windows identifies the processor as:
AMD Custom CPU 1772
GPU Specifications
The graphics processor features:
RDNA 3 architecture
28 Compute Units
8GB GDDR6 memory
Windows and AMD software identify it similarly to the Radeon RX 7600 family, although the Steam Machine version operates with lower power limits.
This design highlights Valve’s philosophy: instead of chasing maximum desktop performance, the company focused on efficiency and compact hardware.
Synthetic Benchmarks Show Windows 11 Taking the Lead
Synthetic benchmarks often favor Windows because they measure raw processing performance rather than complete gaming experiences.
The biggest difference appeared in Geekbench 6.
Geekbench Results
Single-Core Performance
Windows 11:
2,503 points
SteamOS:
2,424 points
Windows advantage:
+3.3%
Multi-Core Performance
Windows 11:
9,750 points
SteamOS:
7,986 points
Windows advantage:
+22.1%
At first glance, this looks like a major victory for Windows.
However, there is an important explanation.
SteamOS was tested in desktop mode rather than Gaming Mode. Desktop mode does not always push the CPU into maximum performance states unless necessary.
Gaming Mode activates performance optimizations through Valve-supported tools such as GameMode, allowing higher CPU behavior during gaming workloads.
Cinebench Shows Impressive Efficiency From Valve’s Custom AMD Chip
Cinebench R24 testing produced interesting results.
Steam Machine performance:
Single-core: 99 points
Multi-core: 554 points
The results place the processor near desktop-class CPUs while consuming dramatically less power.
Compared with the Ryzen 5 5600X:
The Steam Machine processor:
Won single-core performance by around 5.3%
Lost multi-core performance by around 14.1%
However, the comparison is important because the 5600X operates around 65W while Valve’s custom chip runs around half that power.
This demonstrates the advantage of custom silicon designed specifically for compact gaming systems.
Gaming Performance: Windows Wins, But Only Slightly
Gaming benchmarks tell a very different story from synthetic tests.
ETA Prime tested:
Horizon Zero Dawn Remastered
Shadow of the Tomb Raider
Cyberpunk 2077
Each game was tested at:
1080p
1440p
4K
No FSR upscaling was used, meaning the results measured native rendering performance.
Horizon Zero Dawn Remastered Results
At Very High settings:
1080p
SteamOS:
58 FPS
Windows:
59 FPS
1440p
SteamOS:
48 FPS
Windows:
47 FPS
4K
SteamOS:
28 FPS
Windows:
26 FPS
The result:
SteamOS actually performed slightly better overall.
Shadow of the Tomb Raider Results
At Very High settings:
1080p
Windows:
120 FPS
SteamOS:
118 FPS
1440p
SteamOS:
86 FPS
Windows:
84 FPS
4K
Windows:
46 FPS
SteamOS:
44 FPS
Again, the difference was extremely small.
Most results were within only two frames per second.
Cyberpunk 2077 Shows Windows Advantage at 4K
Cyberpunk 2077 created the largest performance difference.
At Ultra settings:
1080p
SteamOS:
74 FPS
Windows:
68 FPS
1440p
SteamOS:
45 FPS
Windows:
43 FPS
4K
Windows:
20 FPS
SteamOS:
18 FPS
Windows achieved a 10% advantage at 4K.
However, both systems struggled at native 4K, meaning most players would use upscaling technologies such as FSR.
Overall Gaming Results: Almost a Perfect Tie
Across all nine tested gaming scenarios:
Windows won:
5 tests
SteamOS won:
4 tests
The final result is not a dramatic Windows victory.
Instead, it demonstrates that SteamOS has become extremely competitive despite relying on Proton.
This is a significant achievement for Valve’s Linux-based platform.
Deep Analysis: Why Windows Does Not Destroy SteamOS
Windows Should Have Had a Bigger Advantage
Normally, Windows should dominate because games are designed primarily for Windows environments.
SteamOS introduces an additional compatibility layer through Proton.
However, Valve has invested heavily in Proton optimization, making the performance gap surprisingly small.
Driver Quality Changes Everything
The biggest factor limiting Windows performance is not Windows itself.
It is driver optimization.
Valve’s Windows drivers use a customized AMD driver package designed specifically for the Steam Machine hardware.
According to testing reports, the package relies on an older OEM-oriented AMD Adrenalin build.
Meanwhile, SteamOS benefits from Mesa, the open-source Linux graphics stack that Valve actively supports.
SteamOS Receives Hardware-Specific Optimization
Valve controls:
Operating system
Graphics stack
Steam interface
Proton compatibility layer
This allows the company to optimize the entire experience.
Microsoft, on the other hand, must support thousands of different PC configurations.
Performance Numbers Do Not Tell The Entire Story
A five-frame difference may appear important in benchmarks.
But during actual gameplay:
Input latency matters
Stability matters
Interface matters
Compatibility matters
A system that feels better can outperform one that technically produces slightly higher numbers.

Should You Install Windows 11 on Steam Machine?
For most users, the answer is no.
The performance improvement is too small to justify losing SteamOS advantages.
Installing Windows means sacrificing:
SteamOS recovery simplicity
Valve ecosystem integration
Steam Controller features
Console-like interface
Official Steam Machine experience
The main reason to install Windows is compatibility.
Some games require:
Riot Vanguard anti-cheat
Certain kernel-level security systems
Windows-only applications
For those users, Windows makes sense.
For everyone else, SteamOS remains the better match.
Is Steam Machine Worth Buying?
The answer depends on what buyers value.
At around the $1,049 starting price, the Steam Machine is not the strongest option for raw performance.
A custom-built Windows gaming PC can often deliver:
Faster GPU performance
Better upgrade options
More storage flexibility
However, Valve’s machine provides advantages:
Compact design
Quiet operation
Integrated power supply
Console-style experience
No assembly required
The Steam Machine is not really competing against DIY PCs.
It is competing against consoles.
SteamOS on Regular PCs Changes Everything
SteamOS is becoming less exclusive to Valve hardware.
The ability to install SteamOS on compatible AMD and Intel systems means users can create their own Steam console.
This changes Valve’s business strategy.
The Steam Machine is no longer selling exclusive software access.
Instead, it sells:
Convenience
Design
Simplicity
What About Xbox Mode on Windows?
Microsoft is attempting to solve Windows’ biggest gaming weakness: the desktop experience.
Xbox Mode transforms Windows into a more console-like environment.
Testing shows:
Advantages:
Faster startup
Lower memory usage
Better controller navigation
However:
Performance improvements are minimal
Desktop tasks remain complicated
Installing non-store applications is still awkward
Xbox Mode improves Windows usability but does not magically turn Windows into SteamOS.
What Undercode Say:
The Steam Machine experiment reveals a major transformation happening inside the gaming industry.
Windows is still the king of compatibility.
SteamOS is becoming the king of simplicity.
The surprising part is how close the two systems have become.
A few years ago, Linux gaming was considered unrealistic.
Today, SteamOS can compete against Windows on dedicated gaming hardware.
Valve’s success comes from controlling the entire experience.
The company does not simply create an operating system.
It creates a gaming environment.
Windows has billions of users because it supports everything.
SteamOS has fewer users because it focuses on doing one thing extremely well.
The future may not belong entirely to Windows or Linux.
Instead, gaming platforms may become specialized.
Console players want simplicity.
PC enthusiasts want freedom.
SteamOS targets the first group.
Windows targets the second.
Microsoft understands this challenge.
That is why Xbox Mode exists.
Microsoft is attempting to make Windows feel less like an office computer and more like a gaming console.
However, changing the interface is easier than changing the philosophy.
Windows was designed as a universal operating system.
SteamOS was designed around gaming from the beginning.
This difference explains why SteamOS feels natural on gaming hardware.
The biggest lesson from these benchmarks is that raw FPS numbers are becoming less important.
Modern gamers care about:
Instant access
Reliability
Compatibility
Updates
User experience
Valve’s biggest achievement is proving that a Linux-based gaming system can compete with Windows.
The biggest challenge for Valve is convincing developers that Linux support deserves equal attention.
The Steam Machine also proves that custom hardware optimization matters.
A weaker chip with better software tuning can compete against stronger hardware with weaker optimization.
The next generation of gaming devices will likely combine the best ideas from both worlds.
Windows will become more console-like.
SteamOS will become more PC-compatible.
The winner will be the platform that offers the best balance between freedom and simplicity.
