MP 7,1 W6900X drivers for gaming

You're most likely stuck with these.

I've seen people modify the latest 6900XT drivers to make it work, but do you want to modify it every time there's a new driver out (which happens frequently)?

You could get the 6900XT and sell the W6900X if you want a Stock option.

Yes, that's not a big issue for me. Tried to modify stock drivers, but got Code 43. Bootcampdrivers work perfectly for now, but getting a bit old.

W6900X got an advantage over RX6900XT it's dead silent even under full load in 5K and got twice as RAM + I can use TB3 cable directly to Studio Display without any adapters. Got it really cheap from Amazon directly from Apple UK.

My RX6900XT stock is pretty silent even under full load. Is the extra 16GB RAM really going to come in handy for you? What do you do specifically that requires that much VRAM?

Regarding TB3, I have dual Studio Displays and use the Belkin VR DisplayPort (~$80 each) to USBC cables and they've been working perfectly fine for years. All features work as well including FaceTime and Speakers and USB ports. Only issue is instead of USB3.0 in the Studio Display rear it's running at USB2.0, which I don't really care about. I do use the rear ports, but for things like a mouse adapter and what not. Anything high speed goes to the top panel or rear.

However it does have another advantage, resale should be much higher for the W6900X MPX module.

On eBay even more common W6800X Duos used are still going AUD$3000-3200. A little less gaming performance is well offset by the extra value of the W6900.

Well OP was asking about gaming, which latest drivers are usually better optimized for what they're trying to do...

And as time goes by, price will plummet on the W6900X.

I got it for 1600 USD, brand new 😉 Also sold my previous 580X and 6600X with some profit. There were times you can get W6600X for around 300 USD out there. Please note GPU prices are going up. It will be always a rarity. When price will drop again I'm gonna get a second one or will sell this one and get something like RTX5090.

The last one from official Apple source currently costs $4577,90 with 24% discount: https://www.amazon.com/Radeon-Pro-W6900X-MPX-Module/dp/B09BS5C8CL?th=1

Is there any how-to how to mod these original drivers so they can work with MPX module? Sure it will require test-mode, but that's not a big deal.

So far I've removed the excludes for MPX modules + copied the original name string from original BootCamp AMD drivers. W6900X is detected, installation is starting but that generates Code 43. Thankfully I was able to fix that via remote desktop.

I dunno who buys these MPX modules, might be old studios or people with extra money to spend. The 6900XT OEM can be found for cheap, especially in the used market and it's the best GPU you can put in a Mac Pro. Old, but still good.

You probably want to install Linux for gaming. To be honest, AMD’s official Boot Camp driver is terrible because it’s outdated and doesn’t work well if you install another non-MPX regular Radeon card in your Mac Pro. You have to remove the MPX module from your Mac Pro in order to use a regular Radeon card in Windows. Drivers from bootcampdrivers.com are also relatively old, and they may cause anti-cheat issues.

Linux gaming is currently very mature, especially with AMD cards. The open-source Mesa driver is much better. I personally have CachyOS installed on my Mac Pro, and its kernel already has built-in T2 support. I have a W6600X MPX and a regular RX 6900 XT installed, and the Mesa driver works great with both cards installed. FSR4 INT8 is also excellent. On Windows, you have to downgrade the regular Adrenalin driver to version 23.9.1 in order to use FSR4 INT8 properly on the RX 6900 XT (with MPX removed of course).

The main downsides of Linux are that Bluetooth doesn’t work, and Wi-Fi download speeds are significantly slower than upload speeds (I observe about 50 MiB/s download compared to 350 MiB/s upload). As a workaround, you can download games on macOS using CrossOver or VM, back up the game files, and then restore them on Linux.

It's also worth noting that CPU performance on Linux is much better than on Windows, likely due to firmware settings set by Boot Camp drivers.

I have another 28-core W-3275M CPU and ran Blender benchmarks on macOS, Windows, and Linux. Here are the results:
macOS: 461.14
Windows: 398.74, 402.76
Linux: 483.90, 487.24

I also observed that the CPU frequency on Windows is capped at 3.2 GHz. I can't exceed this value no matter what I do. However, on Linux, the frequency can boost up to 4.6 GHz when fewer cores are utilized. The Linux kernel's scheduling is much more efficient and can significantly reduce CPU bottlenecks. You can also enjoy the new modern Mesa driver for your W6900X.

You can get a BT/WIFI PCIe combo card for like $20 im sure that has Linux drivers with latest Wifi and BT protocols btw
