Hi Woodcabin,

Just to clarify, the Luxmark scores represents CPU+GPU on Luxball.

On GB5, the scores are:
  • OpenCL: 111359
  • Metal: 173691
More comparison on Luxmark (GPU only):
  • Lobby: 10508
  • Neumann: 42186
  • Luxball: 55211

I'm currently working on the post-install process, I'm still on a fresh install: so no SDDTs more than those supplied in Dortania's 6.9 package (configured as MacPro 7,1).
My fault, I did not read your previous post carefully enough, even so I am surprised that there is no difference between the reference 6900XT and the Sappire OC, it may be that PCIE3 extrangles the cards and does not allow them to reach their maximum performance, almost all the scores I see more than 175000 (metal) are on PCIE4 motherboards, thanks again for the clarification, greetings.

That's even worse: I own a 6800XT (not a 6900XT). But I read somewhere that 6900XT cards were not fully supported yet.

Hey friends
How are you ?
Excited towards the wwdc?

I wanted to find out with someone who has a rx 6800/6900 xt
Is it worth doing this upgrade
I edit video mostly in Final Cut Pro

Have you seen an improvement in timeline and export times?

For example - I previously purchased a Dual Radeon Vii (I added an image)
But I did not really see an improvement in performance

Today I am with rx vega 64 because I sold all Graphics Card I had (had a good opportunity to sell without loss :))


I would be happy for help in making the decision

Many thanks

It totally worth it, I have a 6800xt and Final loves it. It replaces a Radeon VII, totally satisfied!

Popped in the 6900XT with the waterblock and all works well.

However, is there a way to reset the System Overview/System Information so it shows the correct GPU?

Also Metal score looks great so far.

Also it looks like -noweg works but it freezes after some use so I have to use WEG + pikera arg.

Did you clear your NVRAM after changing your args ?

Hey bro
You did tests with 6900 XT on Final Cut Pro
And Davinci Resolve?

Is it worth the upgrade?

Yes of course, but things have been very buggy with with boot.

-noweg doesn't work.
disabling WEG completely doesn't work
pikeramod works but sometimes it doesn't boot into macOS, so trying to figure it out.

I can test for you in FCPX and Davinci Resolve, is there a project you'd like me to test?

So far it's a great GPU, but I think my OpenCore is bonked at the moment, it seems most people don't have the issues I have. Once I am booted into macOS everything is fine. It's basically a 3090 without RT cores. I did some gaming tests too in Windows and it's so nice getting native 4k 60fps on highest settings. Of course the AMD equivalent of DLSS is not here yet, and Ray Tracing performance is horrendous compared to NVIDIA, but so far am happy with this GPU.

I also did some quick Octane X testing and it's so much better than the Radeon VII. Scene loads are almost near instant. I would imagine having 2 of these would be amazing for 3d artists who use Octane. The Radeon VII is going for near $2,000 USD, I paid $1600 for 6900XT Reference (those damn scalpers!) + $250 waterblock so it's almost a 1:1 trade off.

I would also imagine if AMD used HBM2/3 VRAM on the 6900XT it would kill the 3090, but increase the price by $300 (does it matter really with the current market? haha). AMD didn't even use GDDR6X only GDDR6.

Hello, I changed to Mac Pro 7.1 with a 6900XT, you have to remove WhateverGreen.kext, agpmd = pikera and any arguments related to WEG, once the changes are made, with Propper, Control + Command + Shift + R, restart and in the boot OC, reset nvram worked for me, greetings.
