What difference does it make ? Every MP2013 GPU model have same capabilities (number of displays, resolutions, OpenGL and OpenCL standards). Differences are speed and amount of memory.
People are experiencing problems with all models.
I have to say that I'm very worried with all these GPU issues, I don't know what is responsible for them, TB implementation, GPU hardware, overheating or software/driver problems.
Me too, and Apple should be too, because they do not have a clue what is the problem. We will change every part until machine works....GREAT.
Good point!
My mac pro failed again! So on monday I have a genius appointment to get it sorted. basically I have had enough!
Lets see if I get a replacement or a new motherboard. I am hoping it will be replaced. But I doubt it!!
I'm experiencing the occasion display flicker (and sometimes double flicker) which lasts about a second. I'm using an Apple Thunderbolt display with a 2013 Mac Pro (D700) - a combination that you'd think would work without problems.
I'm also really tired of the GPU problems with the nMP. I have the 6C/32gb/D700 model. When it first shipped everything worked under Mavericks( except that .3 update which killed Adobe apps and Resolve) and had to update to Yosemite to use my LG 31MU97 properly at 60hz. Then the problems started with random screen flickering and signal loss, becoming worse months down the road with sometimes fully losing the display signal until reconnected again via DP. Since a couple of days, Resolve 12 and Adobe apps are rendering pink lines and yellow bars into my footage. I already got replaced GPU B one time but I will send the nMP back to the tech support. Thankfully I have since acquired a Windows WS which doesn't have these issues at all.
Really sucks to be hearing about your guys' issues. For such an expensive machine it really is unacceptable to be having this problems. My 6c/d500 had same problems as well, after getting GPU B replaced it is working fine for the moment, we'll see how it goes.
i have similar similar problems which i have described in this apple discussion
https://discussions.apple.com/thread/7045057
I have sent two times the mac to apple service and two times they have said they don't find any problem. The thing i'm more curious at this point is to know if installing windows on the mac could be a solution, i.e. if i'll have the freezings also with windows. I may have read in this thread that someone has tried this successfully.
I have still not tried el capitan, i'll probably try it in the next weeks, but if it doesn't work the only solution could be trying with windows (by the way i am not an enthusiast of mac os, so absolutely no problem to go with windows)

I use my MacPro with Windows 10 in Bootcamp and (actually) Yosemite. Windows runs absolutely fine. There is sometimes a notification like "the graphics driver did react anymore, it was restarted". Windows does not crash at all - it's like a notification "you have new mail"... and you continue working...
That sounds like in fact the problem does occur with Windows.
It's just that Windows is able to recover by restarting the graphics driver - no need for Windows to reboot to fix a GPU hang.
It is a message in the bottom right corner stating "the driver crashed, it will be restarted" - and then the Win-MacPro runs like before, without restarting. Oh yes: the screen goes black for the fraction of a second. But that's it. In Windows it mostly happens, if some video is running (VLC) or a hyper-multimedia-overloaded website is displayed.
So it is "something" that can be recovered - if the driver/system is able to do that...
...but ir rarely happens - there are days where I have Windows running 14 hous without a single restart - without seeing that message.
Most likely there is a screen freeze for 15 to 30 seconds before the blink and message. That's about how long the Windows driver waits for the GPU to respond before restarting it.
...i am talking about a maximum of about one second. It looks the same way if you change the screen resolution.
I do not understand these errors. Today i did some heavy video editing with FCPX in Yosemite - everything you can have running WAS running simultaneously - like a charm....
I'm convinced my problems are down to faulty (loose) Thunderbolt sockets. All six of them are the same. I suggest other folks take a closer look at their Thunderbolt sockets too, because this might not be a software problem.
After todays trip to the Apple store. They where unable to replicate the problem (what a surprise!) They performed a extended hardware check and extended Graphics test. The machine was having a right thrashing. I was really hoping that the fault would show up.
They said that they could take it in a have a look and it would be back with me in 10 working days. I said that this was not good enough. I even asked for a replacement machine which was 256GB SSD and 12GB RAM and a credit note for the difference but they refused. (I was hoping to purchase a few hardware items I have no eye on!)
I asked for a replacement machine but they refused as they didn't have my spec in stock. They said that they would order a machine with the same spec and that I would have to come back and do a straight swap. I was happy with that.
Apparently the Apple technician was saying that a few of these cards are faulty. But how many are faulty is my question?
What I have to say is that I think I was reasonable, I held my ground and also said that I paid all this money and I expect good decent service! Despite me having purchased a lot from Apple. I think this works both ways. i.e customers carry on buying their hardware and good range of top quality products and you will have loyal customers.

I purchased a 6c/16GB/d500/1TB ssd back in June and it was working fine for a couple months, I use it with a HP z24x via HDMI, 1920x1200 60hz, and Yosemite. I do a lot of color in davinci resolve and editing in FCP X, also play games every now and then.
started getting flickers/flashes upon logging in and waking up from sleep, then they'd disappear. over time, the computer would crash and get kernel panics 1) during sleep and 2) during intense renders. Console showed that the GPU was restarting/hanging/resetting during these events. Took it to apple store, they replaced GPU B, it works fine now but rarely I still get screen flashing/black frames for a few seconds when i log in from sleep. I am pretty sure this is just ****** drivers and also im using a 3rd party monitor that technically isnt supported.
I installed El Capitan saturday evening, yesterday in the late evening i had a freezing again. This is the console log

A new thing i noticed is the message 'GPU Driver appears to be hung (over 5 continuous seconds of unreadiness)' that did not appear with yosemite.
