Great news, I hope to see new drivers in the near future as I just got my RX 7900 XTX

Meanwhile, macOS 13.4 is released containing updated AMD drivers for RDNA3, and everyone is mad happy.

It really has that, and not just sarcasm? (it's hard to tell some times).

That's great news if so.

If there is an Apple version of the W7900 it may have support for more displays.

I can't get it to work, any help? After downloading and trying to install the drivers for RX 7900 XTX this is what I get:

You have to remove the W5700X MPX module, and try again with ONLY the 7900XTX installed. After the installer has rebooted and finished installing, turn off your machine, and you can reinstall the W5700X MPX.

Do note that the 7900XTX is still unsupported in macOS.

I hope you installed the two 8 pin power cables after you took that pic.
The cables arrived a day later so actually it stayed like this for a day and it was fine. It just wasn't recognized by the computer.

I have a good feeling that Apple will be kind to MP 7.1 buyers and that the first beta of Ventura 13.5 will have support for RDNA3. We'll get to see that in a few weeks when 13.4 is out and the beta cycle for 13.5 begins.

IDK, but im crossing my fingers that you are right

I don't know, I guess I've heard too much propaganda from the anti Mac Pro crowd.

It may be time in the future to consider ditching MacOS in the future and then eventually Apple.

Hello, can you please advise of the make and model number of the 7900 card? Also, by looking at the picture of the Radeon Pro W5700X installed and the Radeon 7900 card installed at the same time. The Mac Pro should be able to accommodated two 7900 cards without any issues? Just as long as you can figure out how to power both 7900 cards safely! I am inquiring because I would like to purchase two 7900 cards and install them into my Mac Pro 2019. Thank you very much for your time!

Seems you are forgetting that Radeon RX 7900XT GPUs to this day only work with Windows, no one have a clue if/when macOS will support it.

Well this is interesting. I missed the W7800 & W7900 announcement. The W7900 is a 61 TFLOP GPU (FP32). The M2 Ultra in the upcoming Mac Pro won't be able to match that; still less than half if it's 30% faster than M1 Ultra. So it depends what they intend for the M2 Ultra Mac Pro. If it can't use AMD GPUs then it's an upgrade for the Mac Studio, but it's not an upgrade for the Mac Pro. If that's the case I think the Intel Mac Pro will stick around as an alternate product line; at least until they make AMD GPUs compatible with Apple Silicon.

So unless Apple wants to restrict performance, which wouldn't make their customers happy, we will see W7000X series GPUs from Apple. Except it still puts them into an interesting position. I think they cannot release an M2 Ultra Mac Pro that does not accept 3rd party GPUs unless it was near the Mac Studio price. Nobody would buy a base spec Mac Pro at $6K that has crippled performance (compared to AMD).

This is a variation of the same discussion that has been going on for months.

SoCs are very efficient and offer excellent performance per Watt. When scaled up, they offer excellent mid-range performance. But ultimately, they're not magic and are built on similar process nodes to the latest GPUs. So unfortunately a high-end GPU with a massive die and a 400W power budget is going to comprehensively out-gun even Apple's biggest dual-die SoC.

A System on a Chip means the GPU is integrated with the CPU, with a unified memory space. This presents problems with plugging it into a traditional PCIe GPU. Aside from negating any performance advantage of the SoC approach (since you'd essentially just be using it as a CPU), applications for it would likely require specific GPU tuning vs everything else in Apple's product range.

This paradox is why the speculation ranges from a new mega-SoC we know nothing about, to Apple just discontinuing the Mac Pro as we know it.

Agreed, check THIS out

You could install and power two RX 7900 XTX cards with the Belkin cable kit, but RX 7900 series isn't recognized by MacOS in any way so you had to keep at least one card that is compatible with MacOS.
I bought the card just for gaming on Windows.

I am confused. The card you've provided a link to lists a length of 14.5 inches. According to BareFeats, the longest card that will fit into the 7.1 Mac is 12.2 inches. Did you link the wrong card, or did you actually fit a 14.5 inch card in your 7.1 Mac? Incidentally, I purchased an RX 6900 XT video card from Amazon a while ago that lists a length of 11.26 inches, and it did appear that that 12.2 inch maximum size was accurate.

The reference cards do fit in the 7.1 mac pro. dual 8 pin. the over clocked cards are to long. mostly with 3 x 8 pin power requirements.
