The RDNA 2 patch for the 5,1 is awesome! I hope it works. Maybe AVX requirement was speculation. I updated the original post in this thread to include the link.
AMD drivers for GPUs newer than Polaris (including it) after High Sierra require some SSE4.2 instructions, so you need an emulator of these instructions to have the combo AMD GPU + Mojave + MP3,1 to work.Hello I'm trying to understand if the info in this thread also applies to cMP3,1? I'm asking because I've seen this thread specifically about the 3,1 but it's about certain Polaris-based cards only:
MP3,1 never dies - Netkas patched AMD METAL drivers to work with MP3,1!
Maybe MP3,1 got a new lease in life. @netkas made a patch to make AMD Polaris cards to work with MP3,1 Xeon, emulating a SSE4.2 instruction needed by the AMD METAL driver for Polaris cards.

I'm looking for a single-slot solution for my 3,1 to allow me to install DosDude's Mojave or higher.

You need MouSSE:
MP3,1 (& others?) SSE 4.2 emulation (to enable AMD Metal driver)
MouSSE (Partial SSE4.2 Emulator) Public Release Current version: 0.95 (8 Jun 2021) When referring folks to MouSSE, please just link directly to this post, which will always contain the latest version & info.

AFAIK, dosdude1 patched Mojave installer already have MouSSE, you should confirm/get help on the thread below:

Correct.Thank you Alex. Does this mean that if MouSSE is included in a patched OS installation (as I understand is the case wrt Mojave and Catalina according to @Syncretic) I could use any of the cards listed on p.1 of this thread?
Correct.
Seems you are not thinking about all issues involved - CS6 was released back in 2012 and made to run with MountainLion to ElCapitan, but with some issues it runs up to Mojave if you use the workaround below:That's grand, thank you. Then there might be life left in my 3,1.
Can anyone advise me on a single-slot AMD card with low power draw? I've seen the Radeon WX cards but they're very pricey at the moment. The heaviest use is Photoshop CS6 and running two film scanners simultaneously (with Vuescan and Flexcolor).

CS6 is a 32-bit application and will never run with Catalina and newer, when Apple removed 32-bit support.
Another thing, besides the Radeon WX cards, AFAIK there is no single slot AMD GPU supported by macOS drivers. Apple never supported any of the low-end line of AMD GPUs, just some of the mid-range and most of the high end AMD GPUs. AMD GPU support is not universal and you can only make a GPU work that is supported by the drivers.
Most Radeon WX cards require at least 10.14.5 to work and some only work with Catalina / Big Sur, while some were never supported (WX cards with Lexa GPUs will never work with macOS).
Maybe a NVIDIA Quadro single slot, like Quadro K2000, will work better for you since support with Apple native drivers starts with MountainLion and ends with BigSur.
Btw, you should search for a more appropriated thread.
What you are really asking?Thank you dear! You did a great work for old Mac!! My 5.1 together with 6600 xt started... Everything works. I just think, can I somehow return the native Mac bootloader? Or only through Open sours to be loaded?
Ok. Still I did not see any problems with OpenCore, works good. I can even enter to my old High Sierra. Also (WOW!!!) in Monterey I see an option to install Win 10 via BootCamp. Is it realy work? Thank you.What you are really asking?
If you are asking about the native BootPicker, a PC GPU don't have it - @Syncretic patch don't provide pre-boot-configuration support. Anyway, OpenCore provide a fully working substitute.
If you are asking about removing OpenCore, you need OpenCore to boot BigSur/Monterey and without OpenCore you won't have a macOS release that works with a RX 6600XT.
You are forgetting that OpenCore don't support Windows CSM/BIOS installs directly, only UEFI installs. Since BootCamp with a MacPro5,1 is a Windows CSM/BIOS install, it's not going to work, since you now follow OpenCore requirements.Ok. Still I did not see any problems with OpenCore, works good.

Late-2013 Mac Pro support is experimental, with lot's of things not working, at best.I'm confused by this (old) thread - will OpenCore Patcher 0.5.3 let me upgrade my work Mac (2013 Mac Pro, currently on Monterey 12.6.2) to Ventura 13.1, or is it dependent upon which model GPU cards I have in the system?
Which benchmark?Any fellow with a Vega card on a MP5,1 have a comparison benchmark to send?
I got a Asus Strix Vega 56 and I have flashed on one of the bios slots, firmware from the asus vega 64.
My problem is that on my Mac Pro 5,1 either on windows (bootcamp) or on mojave/Monterey the benchmarks I get are at half speed from the average vega PC users. (on both firmwares)
I even setup a PC with a 6th gen i7 and the scores of the card got more than doubled than when the card is working on my 5,1 with 2x 5675 CPUs and 96GB tripple channel ram.
Maybe its the implemetation of the ASUS card (non reference) or all vegas are working slower (almost half speed) on a MP5,1 than a PC for any reason?
anything I can run off,Which benchmark?
Try Luxmark, all benchmarks you ran are basically CPU single thread limiting on the cMP. Unless you use some unreasonable resolution (e.g. 8k), otherwise, very hard to compare the results with other computer that has much faster CPU.anything I can run off,
I more used to 3dmark, heavenWIN, heavenMAC, VALEY superposition or any other you use.
I need just some score numbers and your card info (model maker) so I can compare with mine.
Because I dont believe loosing more than half the speed is the old architecture of mac to blame... I believe somethin else is going on.
I downloaded Luxmark v3.1 and completed the test, the results is 28985 (I even seen a bit over 30000 somewhere in the middle of the test) but I'm still not convinced about CPU bottleneck.Try Luxmark, all benchmarks you ran are basically CPU single thread limiting on the cMP. Unless you use some unreasonable resolution (e.g. 8k), otherwise, very hard to compare the results with other computer that has much faster CPU.
And even you use very high resolution to make sure the benchmark become 100% GPU limiting. The GPU driver itself is still CPU single thread limiting. Therefore, you can never get the same 3D performance on the cMP as other gaming computer.
So far, on cMP, I think only Luxmark can get a meaningful GPU performance for comparison. Almost all other benchmarks are either too CPU limiting, or the benchmark itself isn't stressful enough to measure GPU performance. Blender Benchmark may be also useful. But I only try it 2-3 times, not 100% sure how consistent is. Also, Luxmark is much quicker in general. You don't really need to finish the 2min test, just launch it, and check the samples/sec. That number should keep increasing in the initial ~45s. And that number should be a good enough indicator if your GPU is performing as expected.
e.g. In this example, I got ~50000 (at time = 45s) for my Radeon VII, that's the expected result. For Vega56, I think that should be around 25000-27000 (depends on the actual clock speed and cooling etc). Some Vega64 can reach 30000.
