Success: RX-6800XT in cMP 4,1/5,1 | MacRumors Forums

I posted this in the 6800XT/6900XT thread, but I feel like it's not getting the visibility it deserves, so I'm posting in the main forum, so that people can see that the cMP is STILL going strong, now with the addition of AMD's 6k series cards, all thanks to Syncretic.

I am more than happy to report that @Syncretic 's patch does work 100% to install an RX-6800XT on a cMP 4,1>5,1 running OpenCore 0.8.0, Big Sur 11.6.5, the rest of my specs are in my sig. (@Greggant, if you wanna mention this confirmation on the DMUG youtube, gimme a shoutout! )

As soon as Syncretic made his post, I returned my RX-5700XT and acquired a brand new RX-6800XT.

Whilte I waited for the 6800XT to arrive, I went back to my XFX RX-580, so you will see before and after pics below. Since I had previously already done the Pixlas mod for the 5700XT, it was a simple plug and play.


Here you go folks, as promised, the excitement!: The day I installed it (May 1st), I ran some quick benchmarks: I made a GB5 account a few days later, so here are more results: And of course Windows: As you can see from the various benchmarks, the cMP now easily DECIMATES the 20-core Ultra Mac Studio in terms of graphics processing power. Just had to put that out there as I'm tired of reading BS posts from iSheep around that.

I ran a bunch of different benchmarks in the 6800XT thread, so if you're interested in that, take a look beginning on page 39.

Again, just wanted to put this here, so that it gets the visibility that it deserves. This proves that, thanks to the brilliant work by members of this community, our cMP's are STILL very powerful and capable machines, even 12 years down the line. I want to thank you guys, especially Syncretic, and the OpenCore team for keeping this very capable machine, still purring like a kitten!


Cheers!
