In addition to Intel Arrow Lake desktop performance evolving nicely on Linux over the course of 2025, the Intel Arc B-Series graphics that launched last December with the Arc B580 have evolved quite nicely too with their open-source driver stack. With it coming up on one year since the Arc B580 launch, here is a look at how the GPU compute performance has evolved since that point. Similar Intel Arc B580 Linux graphics comparisons are also coming up in a follow-up comparison on Phoronix.
Today’s article is looking at some of the GPU compute benchmarks carried out last December for the Intel Arc B580 launch day compared to now when running Ubuntu 25.10 and upgrading to the very latest Intel open-source GPU compute stack software. A look at how the Intel Arc B580 open-source Linux GPU compute stack has evolved, primarily for OpenCL, over the course of the past year.
The same Intel Arc B580 graphics card was used for testing on the same Core Ultra 9 285K system. For putting the Battlemage-specific optimizations into context, the Arc A580 Alchemist results from last year and now were similarly conducted for showing the impact of software upgrades on both of these Intel discrete graphics cards.
Back for the launch day testing in December 2025, Ubuntu 24.10 with the Linux 6.13-rc1 kernel and Mesa 25.0-devel Git drivers at the time were used along with the latest public Compute Runtime release.
Now for the end of November 2025 benchmarking was Ubuntu 25.10 with the Linux 6.18 Git kernel, Mesa 26.0-devel drivers, and the latest Compute Runtime (25.44.36015.5). Again today’s article is focused on that Intel Compute Runtime performance while next week is a look at the evolution of the OpenGL and Vulkan graphics performance under Linux.
