Linux vs Windows for AMD RDNA 3.5: Benchmark Performance Insights

Linux versus Windows for AMD RDNA 3.5: When Open-Source Drivers Flex Their Muscles
The tech community has long debated the merits of open-source tools versus proprietary systems, and a recent analysis from Club386 adds exciting fuel to that fire. In tests run on a Lenovo ThinkPad T14s Gen 6 powered by an AMD Ryzen AI Pro 360 and its Radeon 880M RDNA 3.5 GPU, researchers at Phoronix compared Windows 11 Pro with Ubuntu 25.04 using a variety of benchmarks. The results? A tale of two operating systems where Linux not only holds its own but, in certain tasks, outperforms its Microsoft counterpart. Let’s dive into the details and decipher what this means for Windows enthusiasts, programmers, and gamers alike.

Benchmark Breakdown: When Linux Outpaces Windows​

The research focused on several benchmarks, each targeting different facets of GPU performance across graphics APIs. The key takeaway is that performance can vary significantly depending on the workload and the underlying API. Here’s how the tests stacked up:

• Vulkan Benchmark (vkpeak):
• On the Vulkan front, tests using vkpeak presented a mixed bag:
• Linux surpassed Windows in FP32-scalar and FP16-scalar computations.
• Conversely, Windows took the lead in FP32-vec4 and FP16-vec4 operations.
• These results highlight that even within a single API, performance nuances play out in unexpected ways. Linux’s advantage in scalar operations suggests that for some compute-focused tasks, open-source drivers can offer more efficient processing.
• OpenGL Performance with Unigine Heaven 4 and Superposition:
• When switching to the OpenGL API, Windows hoisted a 20% overall lead in Unigine Heaven 4 benchmarks.
• The Unigine Superposition test similarly favored Windows.
• The performance edge on Windows here may be attributed to longer maturation of proprietary OpenGL drivers and optimizations that have been honed over years of industry feedback and development.
• Gaming and Application Tests:
• Xonotic: This open-source first-person shooter saw Linux consistently outperform Windows across all graphics presets. It’s a strong sign that optimizations in the Linux ecosystem, particularly in game engines that benefit from open-source drivers, are paying off.
• Quake II RTX: When the graphics got fancy with ray tracing, Windows reclaimed its position with consistently better performance. This is a reminder that proprietary drivers, especially those designed with cutting-edge features like ray tracing, still hold significant advantages.
• FurMark: With the stress tests offered by FurMark, which evaluates both OpenGL and Vulkan performance, results were evenly split. Both operating systems showed wins under different conditions, underscoring that neither platform has an outright monopoly on performance.

These findings serve as a testament to the evolving landscape in graphics processing where Linux, buoyed by recent advances in the Mesa RADV drivers, is no longer a second-string option. Instead, for specific tasks, especially those tuned towards scalar computations in Vulkan, Linux can leverage superior optimizations.

Summary of Benchmark Findings​

• Linux outperforms Windows in specific Vulkan tasks (FP32-scalar and FP16-scalar).
• Windows leads on OpenGL benchmarks and vector-heavy Vulkan tasks.
• In gaming, Linux excels in titles well-optimized for open-source drivers (e.g., Xonotic), while Windows dominates in ray tracing (e.g., Quake II RTX).
• Results are mixed in synthetic benchmarks like FurMark, indicating room for both improvement and specialization.

The Power Behind the Performance: Drivers and Software Optimization​

At the heart of these divergent performance outputs are the drivers and software stacks employed by both operating systems. Windows has long relied on its proprietary driver model, which benefits from direct control over hardware features, extensive optimization, and support for bleeding-edge features such as ray tracing. Linux, in contrast, uses the open-source Mesa drivers like RADV for Vulkan. These drivers, continually refined by the community and backed by major contributions from AMD, are proving that open-source can match—and sometimes outshine—proprietary solutions.

• Mesa RADV Drivers:
  The latest iterations of the Mesa RADV drivers are doing heavy lifting. They not only close the gap with proprietary drivers where it matters but also bring performance improvements where Windows once held sway. The continuous refinement, combined with the nimble nature of open-source projects where updates and optimizations are rapid, is a game changer for Linux users.
• Translation Layers such as Proton:
  For gamers entrenched in the Windows ecosystem but curious about Linux, tools like Proton have translated many titles to run seamlessly on Linux. This development, in tandem with improved drivers, suggests that Linux could soon become a viable—or even preferable—gaming platform for certain scenarios.
• API Nuances:
  Different graphics APIs (Vulkan vs. OpenGL) emphasize different aspects of GPU performance and driver optimizations. The competitive edge observed in Linux’s scalar processing through Vulkan implies that some workloads inherent in gaming or creative applications might be executed more efficiently under Linux’s open-source ecosystem.

By appreciating the role of these drivers and optimizations, users can assess where their computing or gaming needs might benefit. It also underlines that, while Windows remains the go-to for many professional and gaming use cases, Linux is proving its mettle and could be a strong contender for future setups.

Key Driver and Software Insights​

• Mesa and RADV drivers have rapidly improved, sometimes surpassing Windows optimizations in specific tasks.
• Translation layers like Proton enable a smoother gaming experience on Linux, reducing the gap between Windows-exclusive titles and open-source desktops.
• API-specific performance differences mean that workload type ultimately dictates which OS delivers better performance.

Implications for Windows Users and the Broader Tech Landscape​

For long-time Windows users, the news that Linux can offer better performance in certain tasks should spark intriguing questions. Should you stick with your tried-and-true operating system, or is it time to explore a Linux distribution for specialized applications?

• Gaming Considerations:
  If your gaming regime relies heavily on titles optimized with Vulkan and doesn’t require advanced ray tracing, Linux could offer surprising speed and stability. However, if you’re a fan of visually demanding, ray tracing-heavy games, Windows 11 is still your best bet.
• Professional Applications:
  Many creative and development tools are making the transition to or already operate efficiently on Linux. Developers, video editors, and 3D artists—especially those working in environments that leverage robust open-source software—might find Linux an exciting alternative. Nevertheless, enterprise environments with legacy software and specific Windows-only applications might not be ready for a full switch.
• Hardware Compatibility and Support:
  The Lenovo ThinkPad T14s Gen 6 used in the benchmarks is a niche example. Performance on the RDNA 3.5 GPU can vary across different hardware platforms. For professionals, the reliability of software support, peripheral compatibility, and comprehensive driver support on Windows remains a critical factor.
• Future-Proofing Your System:
  With the continuous progress observed in Linux drivers, the gap between Linux and Windows is narrowing. Future updates—both to Linux distributions and the Mesa drivers—could well see Linux taking a commanding lead in more scenarios. Early adopters might relish the challenge of tailoring a system that maximizes the benefits of open-source drivers, while mainstream users may wait until Linux performance is indisputably superior across the board.

Considerations for Windows Users​

• Gaming that relies on non-ray traced, compute-intensive tasks might benefit from Linux’s evolving ecosystem.
• Professional environments dependent on Windows-only software should monitor these developments before making any major transitions.
• Hybrid setups or dual-boot systems could offer a middle ground, allowing users to experience the best of both worlds.
• As Linux continues to improve, future Windows 11 updates might further drive innovation for better interoperability or driver support.
