Nvidia GTX 980 Ti 6GB with Mac EFI: The GTX 980 gets a boost for Nvidia's latest and greatest GPU

Nvidia’s Latest Graphics Card, the GTX 980 Ti 6GB, meets the Mac Pro 5,1

It’s here, the one people have been waiting for, the Nvidia GTX 980 Ti 6GB with Mac EFI. We wont pull any punches here, this GPU is an absolute monster. Although it shares it’s name with the 4GB GTX 980, it’s actually more like a GTX TITAN X with half the VRAM.
This is the second GPU in Nvidia’s GTX 9XX series that we will be offering with a Mac EFI as part of our custom Mac Pro 5,1 systems, and if we’re honest, it’s the one we’ve been most excited about bringing to the table. This card is just unbelievable, it’s performance is only marginally lower than the GTX TITAN X 12GB, which is the most powerful single GPU we have ever seen.
For example, in CUDA tests such as Octane Render’s OctaneBench, the Nvidia GTX 980 Ti 6GB scores only 4% lower than the flagship GTX TITAN X 12GB GPU. When it comes to OpenCL the GTX 980 Ti 6GB actually scores higher than the GTX TITAN X 12GB in benchmark tests, about 3% higher, with a massive score of 3,232 in the Luxmark Sala test (see screenshot below).

Needless to say, we are hugely impressed by the Nvidia GTX 980 Ti 6GB’s performance in the Mac Pro. For anyone doing visual work, who doesn’t need the marginally better CUDA performance of the GTX TITAN X 12GB, the 980 Ti is surely the ultimate Mac Pro GPU. You can now configure Mac Pro systems with the 980 Ti over on our ‘Configure Your Mac Pro’ page, as well as order them separately by emailing us on

  • Very interesting. So, for someone using mainly applications relying on OpenGL and OpenCL (lightwave, substance designer and painter, FCP X, Motion) what’s the best bang for the buck ? A 980Ti or 2 AMD 280X ? For pure OpenCL results, obviously the two AMD cards combined, but overall ? The 980Ti has 6 Gb of VRAM, and unless the 280X can stack their memory, for 3D apps needing a lot of memory like susbtance painter, the 980Ti may be better… Rough choice, here. I really look forward to read your thoughts.

    • Hi,
      I guess there are a couple of answers to this question. The GTX 980 Ti is certainly the more powerful single card, but two R9 280X cards will have more raw OpenCL compute power than a 980 Ti. Even so, however, I would expect that the GTX 980 Ti would still be faster in many real world scenarios & many apps wont actually utilise two GPGPU compute cards (FCPX will).
      I would personally go for the GTX 980 Ti, but as mentioned, the dual R9s will have more OpenCL compute power overall.
      Hope that helps.

  • Thanks for your inputs. Lightwave is CPU only, except for OpenGL display. Substance suite is OpenGL. 3d-coat on Mac is not CUDA enabled and has some functions based on OpenCL. And FCP X and Motion are my main tools besides Lightwave and are OpenCL enabled. As I plan to buy a custom Mac on your site in the coming months (some cash to spare before… 😉 ), I’ll come back to you when time has come to decide on the right choice, but right now I’m quite tempted by AMD cards.

  • Hi, will this GTX 980 TI work properly in a MAC PRO 4,1 with firmware updated to 5,1 and with two X5690 3,46 Ghz CPU upgrade and the original power supply will be enough? I am also using 4 HD and one PCI SSD MSATA.
    Not sure if I will add a GTX 980 (165W) or a GTX 980 Ti (250W) due power consumption limitations.

  • Hi,
    I just installed a ZOTAC 980TI in a Mac Pro 5,1. OSX 10.11.3
    Is there a difference between the EVGA card and the ZOTAC cards?
    NVDIA does not have drivers for the 980Ti card fro OSX.
    So at first it only kept rebooting with kernel panics. The startup sound over and over. I replaced it with a 660GTX and downloaded the NVIDIA web driver for 600 NVIDIA cards since there are not drivers for the 900 series.
    Now I put the 980TI back in. It boots to ElCapitan, but OPENGL benchmark in CINEBENCH is less than half of the same card put into a PC. it about 42 fps. Same card in an Aurora R4 PC is more than double that.
    So I read your article about how well it works and I was just wondering how. Where do I get the 980TI drivers for OSX 10.11.3? Should I replace the ZOTAC with a EVGA?

  • Hi,
    I just installed a vega gtx 980 ti 6 gb in a max pro 5.1 10.11.4. Mij screen stay’s black. no picture. (dell U2711 dvi-d)
    The system’s boot’s but i the screen stay’s black. Have installed the new’s web drivers and cuda.
    What am i doing wrong? Help

  • Looks great. I used Cinema 4D (VRAY/Octane) and still a bit clueless when it comes to graphics cards. But the 980ti would be a good choice, right? Thanks guys. Love the site.

  • Hi Tom,
    I recently installed a Palit GeForce GTX 980TI in my Mac Pro 4.1 System, running with 64GB Ram under Yosemite (10.10.5). I have the correct drivers installed (346.02.03f11 for 14F2109 System and 7.5.30 CUDA driver). System ran smooth for a week or so until I started experiencing kernel panics in connection with Premier Pro CC2017 /Ae CC 2017 and Me CC2017. I ran all render processes using the GPU(CODA) accelerated Mercury Engine – do you by any chance know what I might have missed out on or if a flashed 4.1 to 5.1 system might run smoother under Yosemite? Or maybe an OS-X upgrade to Sierra might do the trick? I am running out on ideas?
    Also: I connected both mainboard power-connections to the 8-pin plug of the card and used both SATA-connectors of the optical drives to go into the 6-pin of the card in order to run safe on the powerside – might that be wrong?
    Appreciating any help on this matter – thanks a lot and greetings from Germany,
