GPU for FreeBSD, OpenBSD and NetBSD
I'm looking for a good GPU for FreeBSD, OpenBSD and NetBSD. As I know these BSDs have amdgpu, so it should be an AMD Radeon.Can you recommend me any specific model that will be work perfectly for gaming and displaying the X11 desktop. Thanks.

The FreeBSD, OpenBSD and NetBSD projects have different ideologies that impact graphics. FreeBSD is about speed and efficiency and I recall reading that they use a shim on the nVidia windows graphics driver. That will likely give you the best gaming experience in a BSD. They have a large, active forum which can be searched for nVidea and gaming:
https://forums.freebsd.org/ OpenBSD is about code correctness and security. nVidia closed source drivers are contrary to the projects philosophy and nVidia is not motivated to write drivers for OpenBSD. amdgpu(4) is fairly open and my Ryzen 3 2200G (cpu/gpu) runs well. NetBSD has a work-in-progress for nVidea graphics drivers https://mail-index.netbsd.org/tech-x11/tindex.html Last edited by shep; 11th February 2023 at 12:52 PM. Reason: learned to spell Nvidia |

OpenBSD 7.0 incorporated the DRM stack from Linux 5.10.65 so any open source drivers that work under that version of Linux should also work under OpenBSD. My AMD Cezanne iGPU in the brand new ThinkPad P14s Gen 2a I bought recently is supported and https://www.openbsd.org/70.html says that Intel Tiger Lake and AMD's Navi 12, Navi 21 "Sienna Cichlid", Arcturus are all covered. As always check https://dmesgd.nycbug.org/index.cgi for recent dmesg postings and remember that -current is the best bet for recent hardware.

Please don't full quote unnecessarily, it degrades the readability of the thread.
The dmesg postings to which I linked above will show which GPUs are supported by the *BSDs, just check for loaded drivers; for example: Code:
inteldrm0 at pci0 dev 2 function 0 "Intel HD Graphics 3000" rev 0x09 drm0 at inteldrm0 inteldrm0: msi, SANDYBRIDGE, gen 6 Full dmesg: https://dmesgd.nycbug.org/index.cgi?do=view&id=6338 And in respect of CPUs my Ryzen 5850U is a beast: the Cezanne iGPU plays DiRT Rally 2.0 (a recent AAA game) at a consistent >30FPS even in the snow & rain stages under Arch, and the CPU itself crunches through a kernel compilation in just a few minutes.

Yes, OpenBSD uses Linux drivers for amd64. Most Linux distributions have the same problem I have - drm. -current was steadily improving with my Lenovo E595 until 7.0 was released. Since then it has deteriorated to an appalling degree. The system is now almost unusable. But at least the developers are imagining every theoretical security vulnerability and "fixing" them. (Yes I am getting annoyed.) Last edited by sacerdos_daemonis; 29th November 2021 at 03:50 AM. |

An update for the drm code in the netbsd kernel is in the work, and is based on Linux 5.6. Should be included in -10 release if considered stable enough. Testing and bug reporting is highly welcomed. See this thread on UnitedBSD.

Over years, several AMD/ATI radeon display/video/graphics cards worked for me on NetBSD Unix & FreeBSD Unix & (at least for installer) DragonFlyBSD Unix. I used to use nvidia quite a few years ago but got frustrated it was closed hardware... actually radeons aren't entirely open hardware but may be better than no GPU at all. I used everything from maybe old (non-RX) 6000s to vega to (skipped radeon VII) 5700 (XT) to 6900 (XT) and they all worked fine for day-to-day usage, but I didn't try advanced 3D graphics.

Discrete Vega 56/64's cards work on all 3 BSD's. Also on DragonFly BSD for that matter.
