Intel Arc Graphics A580 On Linux: Open-Source Graphics For Under $200
Overall the Arc Graphics A580 was offering good Linux performance in the sub-$200 space and backed with open-source mainline drivers.
The OpenGL and Vulkan support was both in good shape for Arc Graphics DG2/Alchemist and will evolve quite nicely once the new Xe DRM kernel driver is mainlined. There's also other features on the horizon like the Vulkan sparse support that works with the i915 kernel driver.
