Mac Pro 5.1 performance scales neatly with new Nvidia driver. As expected.

    Barefeats initial tests are out.

    The older 980 Ti is still a strong performer. 1080 slightly weaker and 1080 Ti stronger.

    Dual 1080s give twice the performance.

    Typical tests (please visit site for full info):

    Would pascal improve using macos? I have 5,1 macpro with gtx 750 ti and a low end mac pro 2013. The 2013 mac pro just seems snappier moving around the macos. It's hard to explain but the macos graphics just seem faster on 2013. I'm hoping pascal can improve that.

    FWIW it's expected that the 1080 would be close to the 980 Ti, and that the 1080 Ti would be solidly ahead. The 1080 was supposed to basically give you around 980 Ti (or GeForce GTX TITAN X, i.e. GM200) performance for less money and significantly less power.

    macOS.

    So, the GTX 1080 Ti is 17% - 25% faster than a GTX 980 Ti/Titan X (Maxwell), depending on application.

    The driver is admittedly young. Not saying things will inevitably improve. But let's see what happens over the next 2-3 driver versions.

    Can the 1080ti be powered by a standard 2010 5,1 12 core? I'm currently running a flashed GTX 770 and could use a bump.

    How do you know NVIDIA hasn't been sitting on this driver for the past 9+ months? Yeah, it just got released, but that doesn't mean it wasn't done a long time ago.

    2 things- the dual D300's are faster than the single 750TI, and the SSD in the 2013 also helps a lot in perceived performance.

    So, the GTX 980 Ti is faster than a GTX 1080 under MacOS?

    What do you guys think the performance of a GTX 1060 would be? I am coming from an RX 460 (Mid-2010 MP, 3.33 Ghz 6-core)... Do you think it's worth it if I get a GTX 1060 to use for things like FCP X, Motion, PS?

    In the tests that BareFeats ran, yes, the 980 Ti (GM200) is slightly faster than the 1080 (GP104). This is basically expected, as NVIDIA claimed the 1080 would give performance around the original GeForce GTX TITAN X (GM200) at a lower price and with significantly less power. We'll know more as more benchmarks are run and more data is available, there may be other applications where the 1080 beats the 980 Ti. FWIW it's pretty rare that the next-gen mid/high end card beats the previous generations absolute highest-end card.

    I don't speculate and try to stick to what I know. Relative to its release, it's a new driver after a long period of 'no drivers'. I'll follow the development and see what happens. I have no expectations, but I'm also not cynical about it.

    I don't know about MR specifically, but I'm certain that Macs are having an affect on demand for used GTX 680's.

    If you look at Ebay, PC 680 prices remain unusually high and half of 680's listed for sale are flashed for Mac. I think there are many people buying 680's, flashing them for Mac, and flipping them.

    The second D300/500/700 GPU is idle for everything that doesn't specifically detect and use it for computation. For all intents and purposes, that second GPU is useless for standard, every day macOS uses including the desktop UI since it's not used. The UI is driven by a single GPU.

    Speaking of which, does anyone think this means that there will be "Mac-Flashed" newer cards out eventually?

    I watch that EVGA refurb store like a hawk, and I can tell you sometimes the pricing on that store is WAAAAAY out of whack and the prices fluctuate like crazy. Sometimes they will have very similar cards from the same family and one will be $50 higher than the other for no apparent reason. Two weeks ago they had GTX 780s listed which were *cheaper* than the GTX 770s they had listed.

    I thought these cards with this driver meant you didn't need a flashed card to get a startup screen. I'm I missing something?

    The drivers have nothing to do with boot screens. The boot screens happen before the OS boots, and therefore before the drivers even load.

    The only way to get boot screens with a non-Apple card is if it's flashed.

    But now the GTX 1080 (and of course the GTX 1070) is cheaper than ALL GTX 980 Ti, which where all a long time $399.- before. And the most expensive GTX 980 Ti models are not the fastest CLASSIFIED models, but coincidentally the models that can run in a Mac Pro without external PSU (all non-classified with regular base/boost clock).

    Hmmm. Like mirrored the Barefeats benchmark: http://barefeats.com/cmp_pascal.html
