    Does anyone know the specs on what the possible GPU could be? We have heard a lot about the CPU. I know there was AMD drivers in the Snow Lion but what about the Nvidia side. Saw that the laptops might be adopting the 660m. Personally I would like either company. I'm not using the any of the Adobe apps that would take advantage of the Kepler Gpu. What would you like to see.

    Toss up at this point. Rumormill has said NVidia, but they were the same ones saying the Mac Pro was dead, sooooo...

    I've heard that ATI is good to go if Apple will have them.

    I hope they offer a choice between the two. 5 cards would be a nice selection maybe even 6 if they choose to add a ATI pro card aswell. 2 Consumer 1 Pro for each would be cool.

    I say they will go for Nvidia this time. I'm guessing a GT 650 or a GTX 670 at most. Don't think the GTX 680 nor the 690 will be supported. ATI 5870 and 5770 still to be compatible along with previous cards.

    Have they ever offered that many choices before? I would assume 3 cards and one high end and one low and then two of the low cards like the dual 5770.

    The gtx 670 is still a great card but the 680 is super to. Since the 680 is still a dual 6pin they might allow it. Power ratings are pretty low for it.

    I think the GTX 680 is the safest bet for NVidia.

    I'm really hoping for Nvidia. I have had really good experiences with ATI/AMD, better than with Nvidia, but the fact is that Adobe has chosen to support Nvidia's architecture and not AMD's for GPU acceleration. So if you use CS5 or CS6, Nvidia is the clear winner, and it seems hard to imagine Apple would ignore that.

    Once upon a time, you had a choice between an ATI HD2600XT or upgrading to an Nvidia 8800GT, so it's not out of the realm of possibility that both companies could be offered at the same time as options. Also, it's never been easier to upgrade your video card since both AMD and Nvidia now support the use of just about all their current products on Macs rather than just a select few Mac versions.

    CS6 supports ATI and NVidia because Adobe started actually using OpenCL instead of CUDA. Just CS5 only support NVidia acceleration.

    http://blogs.adobe.com/premiereprotraining/2012/05/opencl-and-premiere-pro-cs6.html

    Apple is also a huge backer of OpenCL over CUDA. I don't see why they'd factor CUDA into their decisions when CUDA is one of the biggest competitors to their own favorite, OpenCL.

    yeah they support openCL on a whopping 2 ati cards. and not even the card that is in the mac pro.... Nothing on Apple, but still not exactly a highlight...

    Apple don't lead in this area, they trail.
    Apple need to look at what software developers like Adobe, Autodesk, Maxon, Luxology, to name a few, are implementing on Windows and make sure that OS X provides a framework that provides a good experience for their users on Mac.

    At the moment they don't. Mountain Lion might just change that.

    NVidia GTX680 would be a BTO option due to its high cost, as would and AMD Radeon 7950.

    Apple won't use the GTX690 or AMD 7970 due to cost and thermal considerations.

    Professional GPUs, which means NVidia Quadro or AMD FirePro should be BTO options on Mac Pros

    Correct me if I'm wrong, but the last I heard, there was no mention of GTX680 support in any of the Dev Previews of Mountain Lion. That would seem to indicate that Apple has no plans to officially support it in the Mac Pro. GTX5xx series are supported, however. MacVidCards would be able to verify that, but this is what I thought I've read here.

    I'd like to see the Radeon 7970 as an option. I'd be very happy with that.

    Whichever GPUs don't require an 8-pin.

    Because if they do, I can't fit it in my 2009 :(

    I don't know if that's necessary all inclusive. It's possible they have the drivers and just haven't shipped them yet. The Macbook Pros are rumored to ship with the 650.

    They did. They gave developers the OpenCL framework.

    I'm not saying they won't go NVidia, but CUDA support is about as relevant as DirectX support.

    Well, that's Adobe's problem. They're manually "certifying" each card and then blocking all the others. They just need to "certify" any Mac Pro cards as well.

    I'm pretty sure they have the same "certification" issues with NVidia cards as well.

    The one thing about AMD's is that they shut the fan down when its not in use. They also come standard with mini display ports.

    My official guess is AMD 7xxx series cards.

    If they add an 8 pin plug, we'll see 7970 as top. If they stick with the underwhelming Dual 6 pins arrangement, we'll see 7950. But as I think about this, Apple usually likes to offer the TOP of a particular single GPU range. There are more hints of 7xxx cards in the drivers then hints of Kepler (GTX6xx) but this means very little.

    IIRC, both the 4870 and 5870 had special driver packages that came out with the Mac they got introduced in. This meant that until you got those special OS builds, even if you had the card it was no go.

    I have tested 7970 and GTX680 in every OS build released and I can tell you there is no support for them. I was going to rule GTX6xx out completely because there is no low to mid level GTX6xx card out for entry level, but then I got an email today from a friend at Nvidia pointing out their nifty new GT 640. This would make a perfectly fine "base" card for 6,1.

    http://www.evga.com/articles/00686/#Dual

    So with new cards we will either get a 10.7.4 "Special 6,1 Mac Pro Version" or 10.7.5 or 10.8 GM and it will add support for whichever cards they go with.

    The fact that Nvidia has been going above and beyond to keep current Mac OSX drivers available bodes well for new cards being AMD. I can't picture Nvidia poking & pestering Apple with support for unsupported cards if they were about to launch a new series of cards with them.

    Another reason I think AMD more likely is that we typically get cards MONTHS after they are released, usually right before EOL of "Toc" update. GTX6xx cards just came out in late March, not the usual amount of time needed to solidify drivers by Apple's glacial standards.

    So my best guess is 7xxx series AMD with quite likely a Quadro (or other "Pro" card once available) from Nvidia a little later on.

    The requirement for ThunderBolt tosses a really interesting set of issues in. Apple may take advantage of this and make new GPUs not work in older Macs. (They love to do this) Since there is no TB support on 1,1 through 5,1 LogicBoard there is no reason to expect adding a TB GPU would magically add this support.

    It is even LESS likely that they would manufacture 2 different versions of the cards so that those of us running pre-6,1 could have them too.

    I doubt very much that they will use 6xxx AMD or GTX5xx cards as they are all PCIE 2.0 and it is almost assured that Mac Pro 6,1 will have PCIE 3.0. They can't tout "New PCIE 3.0 throughput on your 6,1....someday when we offer PCIE 3.0 GPUs...for now enjoy a nostalgic look back to PCIE 2.0 with last season's cards" as a sales point.

    So, my take on tea leaves:

    AMD 7xxx cards most likely with 7570 or 7670 or 7770 as base with either 7950 or 7970 as top.

    Slightly less likely is:

    Green team with GT 640 as base and GTX680 as top IS a 2nd possible option. The GTX680 would be an IDEAL Mac card, although it's intentionally crippled GPU performance means that GTX570/580 may still be "the" cards for CUDA/OpenCl until Pro level cards appear.

    Going to be a crazy day on Monday. If they announce that the new machines are already available at Apple Stores I will be heading to The Grove and getting whatever they have.

    Keep in mind that in the past, they announced 5870 but they weren't available for many weeks after. And getting one as a separate purchase took months as I recall. So we may only be able to get our hands on the entry level cards for awhile.

    If I close my eyes, can I make it be Monday?

    If it is Nvidia (I hope so), I think it will be the GTX 670. I am not 100 % certain but the GTX 680 has limited availability.

    670 has within 10 % of 680 performance and is considerably cheaper.

    I think HD7770 as a standard GPU and HD7870 as an option.

    I'd expect the 7970 for ATI, and again, the 680 for NVidia.

    If Apple has to adopt 8 pin power connectors I would not rule that out. In fact, I think that's pretty likely.

    Low end could be the 640 mentioned here. No reason Apple can't mix/match ATI and NVidia like they did on the 06/08/09 Mac Pros.

    It's going to be interesting to see what we get.

    If Apple went down the AMD 7000 series route with no NVidia options I will be looking very seriously at the Dell Precision T5600 series.

    Dell only supply the Precision workstations with NVidia Quadro or AMD FirePro GPUs. That speaks volumes. If Apple want to make more sales they need to make the Mac Pro more desirable in the 3D Graphics / VFX market, which is a strong growth area, and that means Pro GPUs not gaming GPUs.

    Personally, I'm kind of hoping the demands for an EFI-64 bit graphics system in Mountain Lion indicates enough legacy support has been dropped to allow more 3rd party developers to make Mac-Compatable graphics cards.

    Unless I missed something in the referenced link, Adobe seems to be saying that Premiere CS6 supports both OpenCL and CUDA.

    A quote from that page:

    "We got a lot of requests from people using computer systems that couldn’t use CUDA—such as those with built-in GPUs from AMD—to expand our GPU acceleration features to also use OpenCL.

    So, we did.

    In Premiere Pro CS6, nearly all of the things that can be processed with CUDA on certain Nvidia GPUs can also be processed by OpenCL on certain AMD GPUs."

    Further, in the first Q&A, there is this:

    "In our first iteration of OpenCL processing, we weren’t able to get enough performance improvement for these four effects, so they are for now better left on the CPU. But everything else that Premiere Pro CS6 can process with CUDA can be processed with OpenCL, and that’s a lot."

    [Emphasis added]

    Those statements read to me like CS6 supports both CUDA and OpenCL. So according to what Adobe wrote, it seems that it's not "instead of", but "in addition to".

    Again, unless I missed something...
