On the heels of the 2013 Mac Pro price improvements, Nvidia has announced a brand new Titan Xp video card using the Pascal architecture, with a driver release coming soon allowing any Nvidia Pascal-based video cards to be installed in compatible older PCI-e Mac Pros.
The new PCI-E based Nvidia Titan Xp has 12GB of GDDR5X memory running at 11.4 gigabits per second, 3840 CUDA cores running at 1.6 GHz. Nvidia claims that the card allows for 12 TFLOP performance. The Titan Xp is available now for $1200 from Nvidia.
Also announced is the April release of a new version of the beta drivers for Nvidia cards, commonly used in the PCI-e Mac Pro and external GPU solutions. For the first time, Pascal-based cards will be able to be used, opening up the Titan Xp and Nvidia series 10 cards including the previously released Nvidia 1080ti for Macs with PCI-e slots.
The current Nvidia beta drivers require macOS 10.11 El Capitan or 10.12 Sierra, and were released on March 28. Assuming that the OS requirements aren't limited to macOS 10.12 Sierra, the drivers should function on the Mac Pro 3,1; 4,1; and 5,1 from 2008, 2009, and 2010 respectively.
Should the drivers be restricted to macOS 10.12 Sierra, then compatibility is limited to the 5,1 Mac Pro, or the 4,1 Mac Pro with a firmware flashed with a third party utility so it identifies itself as a 5,1 Mac Pro, as Sierra is incompatible with older hardware.
Without some form of external GPU solution, the new Titan Xp isn't compatible with the 2013 cylindrical Mac Pro.
Nvidia was seeking engineers in September for the company's Mac graphics drivers team. The job postings were seeking experience with Apple's Metal cross-platform application programming interface.
