Titan X. Best Mac Pro Card?

[mastermamo]

I have a GTX 780Ti (non EFI) in my mid 2012 6 Core 5.1. It runs off 1x6 pin and 1x8 pin directly off the motherboard. My PCI-e slots are filled by a GT120 for boot screen purposes, a USB 3 and esata port card and the last slot is taken up by a 4 port Firewire 800 card. No drama whatsoever. I don't understand the need to grab more power from the optical drive bay etc and to my knowledge the 780Ti is far more power hungry than the Titan.

It has been confirmed. The card requires an 8 Pin and a 6 pin power cables. I currently have the regular Titan running in such a configuration on internal power with no problems for over a year (using the optical drive SATA power and the HDD bays to supplement the 6 pin) so I am confident the Titan X will be just fine since it uses the Maxwell architecture which is more power efficient. Hopefully it wont be more than $1500. If so I could keep my system for a while longer. By the way Netkas, thanks for all the work you'd done to bring more EFI ready cards to the Mac Platform. Truly appreciated.

Confirmed, have been running a flashed 12Gb Titan X (macvidcards) in a MP5,1 for some time now & simply with 8/6 pin cables, Nvidia drivers; requires no additional power etc. Depends on what you want to use it for: Titan X has both good CUDA & OpenCL grunt & I use it to wring a bit more performance out of FCPX (OpenCL) and DaVinci Resolve (CUDA). Driving a UHD display and a 4k display. Works well, but the bump wasn't that overwhelming by comparison to my last 4GB GTX 980. Still, did improve matters a little. Apparently, the 6GB GTX 980 Ti has slightly better OpenCL performance to the Titan X and overall may represent the 'Best Mac Pro Card' relevant to assumptions about use, applications, MP version etc.

AWESOME

The differences in performance between 6 and 4gig cards will be marginal to say the least. Most people misunderstand the fact that the amount of VRAM available applies more to factors like gaming. Most feel the more the VRAM the better the performance. Not true in most aspects as Adobe apps using Cuba and Resolve using OpenCL manages the VRAM in very different ways.
I would stick with the 4gig card.

Am running both a titan x and a 980ti in a 4,1->5,1 and the ti is indeed a bit faster, both in cuda and opencl

I also have both cards, GTX Titan X and GTX 980 Ti. The 980 Ti is a little bit faster, but if an application exceeds the 6 GB V-RAM limit the GTX Titan X is much better, therefore future-proof.

What does one do with a 12GB card in a Mac Pro? Is this card an example of diminishing returns, considering the probable cost?

The 12GB GPU VRAM is needed for using multiple nodes in Resolve especially if using Neatvideo noise reduction.

The dreaded "out of memory" errors occur w/ 6GB.

Well it depends on the system. I had a GTX 780 6GB and currently the Titan X. The 780 caused my mac pro to shut down when exceeding 100% power draw (which can happen in some specific situations). Since then I am using an external PSU

The difference between the 980 and 980Ti is definitely not only the VRAM

I also have a flashed 12GB Titan X. I was wondering do you have sleep issues running Sierra 10.12.2?

How about the non-flashed Titan X (Maxwell)

Anybody havig problems with it?

Works great!

 

[itdk92]

Could I ask for some help from any of you who already has a Titan (Maxwell)?

Could you test it on a x4 slot and on a x16 slot?

In theory there should only be a minimal difference, but I am very curious.

Maybe smth like a geekbench and a luxmark or 3d benchmark?

Thank you so much!

How about the non-flashed Titan X (Maxwell)

Anybody having problems with it?

I've used non-flashed PC Maxwell Titan-X 12GB cards via eGPU over TB2 on several Macs, no problems on 10.12.2, some dance work on 10.11.6. The eGPU has a 16x slot, but TB2 only provides 4 lanes of PCIe 2.0 - for CUDA, I see 0-10% performance loss based on the Mac used w/ it in real world use.
