  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

Can Adobe CS6 Use 2688 CUDA Cores?

GTX TITAN Signature Superclocked edition has just landed here. :) Testing will commence this evening.

Readback performance is going to continue being better on Quadro cards for now -- or at least in this manner as Scratch and many other OpenGL based software handles it. Comes back to legacy OpenGL 2.5 and prior implementations using glReadPixels as the primary readback method. Newer OpenGL specs have brought us superior ways to handle readback with direct framebuffer access and large frame memory transfers, many of which are handled through extensions, so the shift over is not always that simple. One of the common work-arounds I'm seeing is that developers are resorting to using a function built with CUDA or OpenCL to replicate the same functionality in a way that's faster on the GeForce and Radeon cards, whereas the older OpenGL functions are faster on Quadro and FireGL cards. ...Yes, AMD has this same issue.

Based on the Scratch profiler, if I were a Scratch user, I wouldn't be yanking that Quadro 6000 out of my workstation anytime soon.

Anyway, I'll be starting tests with the Quadro 6000, Titan and GTX 690 and various combinations of each. I'm expecting the Titan + 690 to be the winning combo for Resolve. Titan should be the winner in Premiere, assuming drivers are up to snuff. Quadro is still going to rule for pro OpenGL stuff, as we're seeing with the Scratch profiler -- just the way I'm expecting it to unfold.

I'm curious to see just how far I can push the clock speed on the Titan...
 
Tested some things and swapped some cards around last night. Here's my initial impression of Titan... Don't bother, at least not until the drivers mature a bit. We went through this same ordeal with the GTX690. It was nearly a month after I got the card before I could really put it through its paces.

Biggest issue I have at the moment is the drivers are just straight-up flakey. And I expected this. I'm being told to expect a new beta driver sometime in the next 48 hours...

The good news -- Games are smokin' on the new card. Performance seems to be on par with the GTX690, there are no games right now that I'm aware of which can stress either card to its max. I guess I could strap 3 x 30" displays to it. Right now I just have one attached. The DVI-I port does not appear to put out a proper DVI-DL signal, can only get it from the DVI-D port, so I can't run dual 30" displays, or at least not the two old Dell's I have allocated to this system, until I get another DisplayPort to DVI-DL adapter.

I really want to test QFHD/UHD @ 60Hz via DisplayPort, but don't have the monitor to do it [yet]. Stacey, any word on that front from you and your 4K display?

I need to come up with a good way to benchmark GPU performance in Premiere. Everything I'm trying, even stacking multiple transitions, is not stressing any of these GPUs. Running H.264, R3D or AVC footage taxes out the CPUs before the GPU gets loaded up. Just reaffirms my other comments when I tell people that the GPU is not all that they want it to be and other bottlenecks usually kick in first, in Premiere anyway.

Candle light test in Resolve so far. GTX690 is the winner at the moment, the Titan gets me two more blur nodes than the Quadro 6000. Have not tried pairing any cards just yet. I have to reconfigure some power leads to make it happen. 690 is winning out because it is two cards in one slot and the extra precision and FP64 abilities of the Titan (or GK110 / Tesla K20X / etc..) are not something Resolve benefits from. I'm picking Titan as primary GPU with 690 installed for additional compute to be the hands-down winner for Resolve. Of course, I'll have to find a way to make that work. Need more power... Z820, I curse you and your cramped slot arrangement and puny 1125W PSU.

Will re-run all these same tests on my SuperMicro based dual Xeon system. Probably this weekend. I may hold off on further tests until I get a driver update.


I wish EVGA were selling a single slot-width liquid cooled Titan as they do with the HydroCopper 580's and 680's...


The Signature SuperClocked Titan card came with a nice mouse pad and a black EVGA t-shirt that actually fits me....

Hey Jeff, this comment peaked my interest. I was under the impression that Resolve used the Primary GPU for GUI only. I always thought as a result the primary graphics card made very little difference to Resolve but would be the card primarily used by other programs (Premiere etc). Does the primary GPU also affect performance for Resolve too?

Have you spoken to EVGA or nVidia about this? Is there a fix in motion?

I need two dual links (as advertised) AND the display port.

We had old QuadroFX in GUI slot and 3x gtx680 in Cubix. We moved one gtx680 to GUI and with the two left in Cubix performance very much improved. Apparently they did something from Resolve9 to take advantage of the GUI card in accelerating Resolve.

Looking forward to this tests!! Also for all supermicro potential buyers I might scared with all my threads with problems. I want to add that my motherboard or something in a cpu is not function. I will go back to my reseller and change mother board and if that dont fix it. Try new cpu's. Post results on reduser of course.


Single slot 680? what are you talking about, post a link!

Good to know Robert! Thanks :)
 
Yep, Robert already pointed it out. Resolve 9 now uses CUDA acceleration on your GUI card as well, if available. Actually Resolve 9 runs quite well with a single GTX580/ 680 / Quadro 6000 card. And it likes it even more when you can add another GPU or two.

Have not got to more testing, but I think the combo of the Titan + 690 is going to be the best of the cards I'm testing for Resolve. I'm not sure which one will work better as the GUI card. I'd prefer the Titan as the primary/ GUI as it's going to be the superior card for most everything that doesn't use multiple GPUs, but I have a hunch that Resolve might run better with it flipped, the more I think about it.
 
Jeff,

Not sure if you have the monitor to test this or not...but can the Titan output 10bit over Displayport like the Quadro's do?
 
Have not got to testing with any 10bit+ capable displays. Actually have only run a couple more tests and I'm awaiting a driver update to see if it fixes a couple glaring issues. Titan screams in 3DMark and the DirectX benchmarks. Its performance on the Resident Evil 6 benchmark were great, but the GTX690 was still better. The bet drivers dated for last monday, March 4, are a bit speedier than the Feb 21 launch drivers, but a bit more unstable. There was talk of new drivers coming out any day now, but who knows... I'm probably going to proceed with some testing this weekend anyway, if time allows, because I don't think I can get to it next week.

Jon, unfortunately we can't utilize any GPUs in Thunderbolt expanders on Mac OS. It's a limitation of some sort in the graphics driver interface and which system bus(es) the GPUs can exist on. Apple is aware of this restriction, but no one knows if they have any intention of "fixing" it. You can use a GPU via Thunderbolt under Windows. That said, Thunderbolt is still rather limited compared to what these GPUs are capable of tossing about.

I have this working now. After some issues, I did a complete wipe of the drivers and related files and a fresh install. Both DVI ports are driving 30" displays just fine.
 
All of the single GPU tests are complete now... Have a few observations.

* TITAN drivers are shit at the moment. This was to be expected, will test again when the next WHQL version is released.

* TITAN performance is very erratic and noticeable in all apps. This will undoubtedly improve as the driver support improves.

* The GTX690 is the superior card of the three tested under most circumstances. The TITAN does show some advantages, as does the Qudro 6000.

* Resolve 9.1.1 is seeing the GTX690 as a single GPU and not as two separate GPUs, all cores are accounted for or so it seems. This hampers its performance when treated as single GUI+CUDA card. The TITAN looks like it wants to be the superiror single card option for Resolve, but its erratic performance leaves it lagging behind the GTX690 in some tests. TITAN performed especially weak for noise reduction.

* In DirectX games/apps the 690 crushed all. The TITAN had superior numbers at 1080p and lower and with smaller polygon counts. In the Resident Evil 6 benchmark the 690 was the smoothest performer and blew the TITAN out of the water at 2560x1600. In 1080p, the TITAN showed some amazing frame rates -- over 180fps at times, but once again the erratic performance brought it down from the clouds and it would go from huge rate spikes in the 160-180fps range and suddently crash to 10fps. In the shot at the end of the first sequence, for those familiar, the camera gives us a wide view with lots of infected zombies and the polygon count is huge. The Titan dropped to 19 frames in this sequence, the Quadro 6000 dropped to 14fps. The 690 held firm at 29fps.

I realize most here are probably not interested in DX and game performance, but it is a way to look at the cards' abilities.

Dual GPU testing shall commence now... I have the power issue sorted, but I will be unable to test both the Titan and 690 in the Z820 without an external power supply or I must sacrifice my internal RAID as it currently exists. I'm going to just conduct the dual GPU testing on my SuperMicro build. So far I'm getting identical results between the Z820 and SuperMicro on the single GPU testing.

The standard candle test has become the defacto standard for testing resolve performance. That is what I'm using, but I'm going to develop a new test to see if I can better strain systems of the magnitude I'm using. The testing chokes the system, but it doesn't seem to peak the CPUs much, nor the GPU. There's a bottleneck of some sort that's holding back performance with this benchmark that doesn't seem to rear its head in any of my "real world" usage.
 
Have most of my results from dual-GPU testing now. It seems I now have questions in regards to Resolve performance. I need to devise a better test than this standard candle thing. Performance increase was quite noticeable with the second GPUs in Resolve, but GPU metering showed that even though the system bogged down under the strain of the nodes, the GPUs themselves were not strained.

Full write up in a new thread soon.. For what I have up through this point.

The OS is windows I asssume.
Is this a desired feature or a bug?
Is the whole RAM 2x2GB seen as one chunk of 4GB? Relevant for >4k resolutions.
It would be nice to have the Titan in GUI and 4x gtx690 as GPUs for max performance in windows (in Mac 680gtx as GUI and 3x gtx690 as GPU).

PS. We have problems getting Quadro K5000 and gtx680 to work together in our Supermicro station. Still working on it. And awaiting the ordered Titans next week.

Glad to hear that!

Did you use a tool to wipe the drivers?

BTW - do you find better CPU coolers allow you to stay in Xeon's TurboBoost mode longer - and how does one measure when one is in TurboBoost mode?
