Hi, is there a reasonable way to add AVX2 support to a Mac Pro 6,1? Is there some thunderbolt PCI express thing I can plugin with a card or something?
Got a tip for us?

MP 6,1 Is there a way to add AVX2 support to Mac Pro 6,1?

There isn't even unreasonable ways.
AVX2.0 is part of the instruction set of Xeons one generation later - starting with Xeon E5 V3 - that is incompatible and can't be installed to the MacPro6,1. The only Mac Pro that have AVX2.0 support is the 2019 Mac Pro.
No.
That's unfortunate. Aside from that still seems like a perfectly viable machine but I guess it is a decade old.
How can I tell what newer machines have AVX2? My 2015 iMac 5k appears to and that is only a few years newer than my MP 6,1. Do the new Mac Minis M1 and 2 have AVX2?
AVX 2 were introduced with Intel Haswell processors, so, some Macs year model mid-2013 and then all late-2013, with the exception of the MacPro6,1, have AVX 2 support. The first Mac Pro to have AVX 2 support is the 2019 Mac Pro.
Intel Xeons are always behind the Core series (also there is no i7 with AVX 2 support with the same LGA 2011 socket of 2013 Mac Pro, only with the incompatible LGA 2011-3).
Apple Silicon have different SIMD/vector instructions (NEON and etc) that are more or less equivalent of the most recent Intel AVX instructions.

Question, why is it that a 6,1 can run Sonoma With OCLP. why do the older GPUs work in Sonoma like the d300-700 but the new Navi 2 Rx 6800xt can’t work. I know it has to do with avx2 but I am just wondering why the older GPUs work and the newer ones don’t, do the new drivers for the Navi 2 have avx2 built into them in Ventura as a-posed to the drivers in Monterey? Just trying to understand this better. Thanks
All Ventura and Sonoma GPU drivers require AVX2.0, Apple added the requirement (compiler flag) of AVX2.0 when the drivers were compiled.
OCLP is injecting modified Monterey drivers into Ventura/Sonoma, this works relatively good for some GPUs and not for others. OCLP have limited manpower and not all GPUs, so, the most commonly used ones get better support. NAVI GPUs are currently unsupported.
Although I have been back on Sonoma for the last couple of days on my 5,1, my Monterey boot is more reliable.
Sonoma is mostly stable with my flashed Sapphire RX-580 8GB. But there are occasional crashes especially if I let it sleep over night. I just shut it down when not in use.

Interesting, but did you noticed that this thread is about late-2013 Mac Pro?
Yes. But AVX2 related issues should replicate, shouldn't they?
BTW, a while back, you warned about Logic Pro reliability under Vetura and Sonoma. I tried to do more serious work on the CMPro 5,1 under Sonoma (normally I use a Mac Studio M1 Ultra,) and Logic hung after a bout 2 hours. You were correct, sir!
I am back to using Monterey. The good news is I found the Project file format compatible between 10.7.n and 10.8.n, at least for the features I have used.
Well, there is Intel's Sofware Development Emulator that you can try.
It basically fully emulates all missing CPU functionality on units it is run on.
Expected to be slow to use on old Macs where it has to emulate more things.
The reality is that no one appears to have looked into it seriously here yet.
The 2013 Trashcan might be one of the better candidates to try it on.
This option is basically the only path left to keep stuff working.
Since there are no LGA2011 i7s with AVX 2 support, this is not even possible.
Only LGA2011-3 i7s have AVX 2 support - these have the same incompatibility problem as the later Xeons V3/V4 - exact same FCLGA 2011 physical socket, but with a different electrical pin-out and requiring a new chipset/motherboard - these are called R3 or FCLGA 2011-3 for differentiation.
The FCLGA 2011-3 CPUs are not compatible with 2013 Mac Pro or even FCLGA 2011 PC motherboards - different chipset/VRM and etc.
Hey @tsialex as this was posted back in July I'm just wondering if anyone has found a way to make it work, only reason I ask is bc a editor sent over Premier Pro files today and I couldn't open them.....
