[Success] Radeon RX 6800 XT - Big Sur

6700 XT doesn't work with these new RDNA 2 drivers... :/

Not yet, but Navi22, and Navi23 are still in the Framebuffer.kext. Just not in the 6000.kext.

Yeah, I just tried this. RX 6700 XT (Navi 22) and RX 6600 XT (Navi 23) do not work.

No they aren't......

Yes they are: 73DF is RX 6700 XT

Thats for AmdGpuWrangler, which has every Navi type device-id in it, has nothing to do with a controller.

I see, sorry for the confusion.

Not in the info.plist they’re still in the kext. They had and then removed the info.plist IDs with Navi21. I’m not saying the IDs are there, just the code that has been there all along. It has not been scrubbed, so that is encouraging.

Again, they removed them completely from all binaries. As you can see in the screenshot in a disassembler, you can search for Navi 10,12,14 and 21 and you will see code for the controllers. Searching for Navi22 or Navi23 show no matches for controllers.

I’d expect 6900xt to be at least 200 at 8k otherwise for folks who solely use resolve, it doesn’t make much sense to go up.

Oh cool cheers for that. I do wonder if there is a bottleneck with this test? The numbers don't seem to scale correctly for the GPU as they do for the CPU, maybe I am missing something.

I hope the improvement in your score is due to Metal over OpenCL, that could account for the 6000 cards performing poorly under Resolve too. We need test with Pugetbench and see if it improves on this.

Edit - Pugetbench Resolve is Windows only for now - damn it.

Was the Navi22-23 support in the controllers right before this release, and just removed? Or is this change or removal the same one or similar to the what was done in early betas with Navi21 i.e. the Navi20 Devices in the info.plists? The removal of Navi20 in the plist.

AMDRadeonX6000Framebuffer.kext still has some Navi22 code, AMDRadeonX6000.kext has nothing. All I'm saying is that they didn't remove it (from this FB kext) which is a good thing.




Navi29? Navi24-26.
