Default AMD CPUs

Which is the latest CPU from AMD does OpenBSD 5.9 or OpenBSD 6.0beta support? And the corresponding motherboard?

Do you mean only CPU or entire APU (CPU + GPU)?

Sorry that my post was ambiguous. Which latest AMD CPU does OpenBSD 5.9 or 6.0beta support? What about the latest AMD APU?

CPUs shouldn't be a problem. x86 is x86 for the most part and I don't think I've ever seen an OS that wouldn't run on a newer CPU. The only drawback is that OpenBSD is still using GCC 4.2 for some components, so it won't be able to take advantage of some of the newer processor features.

The man page for radeon(4) indicates that there is support for Radeon APUs. It looks there were some drm and driver updates completed in March and April according to the cvs list. You'll need to run current to take advantage of that.

I'm beginning to look at updating my main workstation and have been following this. To my knowledge, OpenBSD's radeondrm code is presently based on the code from Linux 3.8.

Log message:
Update inteldrm to the code from Linux 3.14.52 (which corresponds to
commit 48f8f36a6c8018c2b36ea207aaf68ef5326c5075 on the linux-3.14.y
branch of the linux-stable tree). This brings preliminary support for
the GPU on Intel's Broadwell CPUs. Don't expect these to work
perfectly yet. There are some remaining issues with older hardware as
well, but no significant regressions have been uncovered.

This also updates some of drm core code. The radeondrm code remains
based on Linux 3.8 with some minimal changes to adjust to changes in
the core drm APIs.

Joint effort with jsg@, who did the initial update of the relevant drm
core bits. Committing this early to make sure it gets more testing
and make it possible for others to help getting the remaining wrinkles
straightened out.

Ah ok. Apparently the radeon manpage is for what Xorg supports, not what the kernel supports. There was a post on @misc that indicated that newer radeon cards require LLVM support in mesa.
