  • can Resolve for Mac run on multiple GPU’s?

    Hello DaVinci Friends

    Just wondering if Resolve for Mac will support multiple NVIDIA GPUs for acceleration,

    Can you use a GPU-Xpander Pro 2 with 2 GTX 285 cards inside running externally.

    it would be great solution for performance.

    Thanks in advance

    Unfortunately, due to limitations on the current Mac hardware & OS there’s no multiple GPU config possible.

    No idea if this’ll ever change as traditionally Apple have never mentioned it might change. They’d need to add more PCIe 16x slots as currently, if you had 2 x double size GPU cards you couldnt add Fibre/SAS for storage or IO cards….

    And what happens if you connect a Quadro Plex ?

    Hi Sascha, I agree with you

    It would be good to find out from DaVinci or Black Magic if Resolve can support external multi GPU devices like the ones mentioned to accelerate processing .

    if possible or not, could someone respond please

    thanks in advance.

    Hi all, we continue to review the GPU processing options available from third party hardware vendors, which to date none provide a significant advantage to our working configurations. There are driver, operating system, power and bandwidth limitations on and off the motherboard PCIs buss and limits to slot count and the bandwidth needed on each of those slots. Adding extra slots via an external box does not necessarily increase bandwidth and extra cards off-board need low latency access too. Keep in mind we have developed and tuned Resolve to perform multiple nodes/layers of grading in real time with 4:4:4 HD resolution files on the Mac. Given we have shown we can do this, and will start shipping soon, if there was some other solution that would speed this up, to give you more power, we are pretty sure we could make that work too. We just have not seen anything so far to help us and you in this area.
    Let’s see what Apple release in the new MacPro and remember, new GPU’s from Nvidia are always in development.

    No new Mac Pros…
    Will it run on the iPhone 4 ?
