Shouldn't be a problem, based on the Phoronix review.
What you're probably wanting to know first up as a Linux gamer/enthusiast... All of the Radeon RX 9070 series support is upstream in the Linux kernel and Mesa. For my pre-launch testing I have been successfully using the upstream code within the Linux kernel and Mesa -- no yet-to-be-merged code or any experimental branches or anything along those lines.
We've already got kernel version 6.12 in stable, so as long as you're on linux-current
it should be pretty much plug-and-play. YMMV of course.
EDIT: Actually we may be a bit behind on mesa. We have 24.3 currently, but looks like it may be a bit buggy with these cards. Wondering if @ReillyBrogan is looking for a reason to upgrade again?
