Intel’s latest graphics card, the Arc Battlemage B580, has generated a mix of excitement and disappointment following its release. While initial reviews praised its performance on Windows, recent benchmarks conducted by Phoronix reveal that the B580 struggles to keep pace with its predecessor, the Arc Alchemist series, when operating under Linux. This discrepancy highlights potential early-stage issues with the Linux drivers for the new GPU.

Intel B580 Performance Overview

The debuted last week and was generally well-received for its capabilities in Windows environments. However, Phoronix’s findings mark the first comprehensive comparison of its performance across both operating systems. 

The benchmarks included comparisons with the Arc A770 and A580 models, which are older generations of Intel’s graphics cards. Unsurprisingly, these previous models performed slower than the B580 in Windows; however, they showcased a different story when tested on Linux.

Benchmark Results

In a series of gaming and computing applications, Phoronix aimed to evaluate the overall performance of Intel’s Linux drivers rather than just peak performance in high-end games. The results were telling: the B580 actually underperformed compared to the A770, which was nearly 2% faster overall in Linux benchmarks. 

This is particularly notable given that the B580 outperformed the A770 by 25% in Windows tests. The shift in performance between operating systems was significant, indicating a 27-point drop when transitioning from Windows to Linux.

Interestingly, Intel’s previous generation GPUs showed an opposite trend in Linux performance. 

The A770 and A580 experienced boosts of 19% and 20%, respectively, when tested on Linux compared to their Windows performance. In contrast, the B580’s performance dipped by 8% in Linux relative to its Windows results.

Vulkan API Challenges

A critical area where Battlemage’s Linux drivers appear to falter is with the Vulkan API. Notably, there were no benchmarks where the B580 outperformed the Alchemist GPUs when Vulkan was utilized. In scenarios where all three GPUs struggled under Vulkan, the B580 lost more ground than either the A770 or A580. Conversely, OpenGL tests yielded better results for the Battlemage GPU.

Performance at Higher Settings

The B580 also faced challenges with higher fidelity graphics settings in certain games. For instance, in Yamagi Quake 2—an application that runs natively on Linux—the B580 struggled significantly with multi-sample anti-aliasing (MSAA) enabled and displayed a more considerable performance drop at higher resolutions compared to its predecessors.

Positive Aspects

However, not all news is bleak for Intel’s latest offering. In specific titles such as Counter-Strike 2, the B580 outperformed both Alchemist GPUs and demonstrated stability while running Hitman 3—an area where both the A770 and A580 encountered crashes. Despite these successes, it remains clear that overall performance still favors Windows for gaming applications.

Future Prospects

Intel has historically shown a commitment to enhancing its hardware’s performance within Linux environments. Given this track record, there is optimism that improvements will come for the Battlemage series over time. 

Considering that Alchemist GPUs have had over two years to mature in terms of driver support and optimization on Linux, it is reasonable to expect that Intel will address these early teething issues with the B580 sooner rather than later.

Conclusion

As Intel continues to refine its graphics technology and drivers for various operating systems, users and enthusiasts alike will be watching closely to see how future updates can enhance the performance of their latest GPU offerings.
