Quadro GPU performance

Recommended Posts

I currently use two GeForce RTX 2080TI cards but will be testing a Quadro RTX 6000 as a possible upgrade.

This is largely based on this SGO support article https://support.sgo.es/support/solutions/articles/1000247927-nvidia-quadro-or-geforce-

is there any documentation that is available that goes deeper into the bus management of the two cards. In almost all online content the two cards are considered largely identical in architecture and differences are said to be minor. This article stands out it saying the Quadro cards are far superior.

I would love to find out more. Is there NVidia developer manuals or anything like that? Couldn’t find anything via Google.

Of course I’ll see some performance data soon as I run a few projects against each other.

The  main differences are;

 

- The amount of graphics memory. If your tiemeline does not need the etxra it does not make any difference,  but if it need it the Quadro will be much faster, as otherwise the GeForce will swap to system RAM or even crash at some point.

 

- The Quadro upload and download textures in full duplex mode troufgh the PCIe bus, it can be upload image layers for next frame while  downloading the previous frame at the same time. This is specially important at high resolutions, and it makes a significant difference in realtime capabilitiesplayback

Thanks Javier. 

Right, that's exactly what the SGO article also states. What I was looking for is some documentation on that. I haven't been able to find anything from NVidia or elsewhere on the web.

I'm using this article to justify a much more expensive card. And a lot of folks are skeptical since so many other comparisons call the cards equal. So I'm looking for some more information to back this up. I should have my card for evaluation soon so I can do some first hand testing of both of them in parallel. But if this is a key feature, I would expect NVidia to document that somewhere.

Regarding NVidia I do not have documentation, but it is easy to see. Just play a complex timeline (for example at 4K with a Comp3D having  multiple layers and you will see)

 

Apart from that, Quadro boards are recognized to be more stable and long lasting under heavy rendering over the time. We have barely seen any Quadro burned over the years, but many GeForce were fried.   In principle the price difference still does not compensate for this, as you can always buy the next GeForce when the previous one is burned, thus having the new model  and still saving money.  But if you work in client attended sessions or very tight agendas you may think differently.

Also, if it is about economics a good way to save money is to use 1080ti or a P6000 (even if second hand), as the RTX does not really provide performance gains for the particular case of video processing in Mistika, only in rare cases.  But If you want RTX , the RTX 5000 is probably the sweet spot.  It is close in performance to RTX 6000, although with less memory. 

Personally, what I would do is to  check how much graphics RAM you use in your most complex timeline (after working for a while on it and passing trough all the Timeline). You can see that in the Task Manager (look for GPU options).  I think it s the best way to choose the right model if you are in doubt.

Received my Quadro card yesterday and will run some performance comparisons.

Does SGO or someone have a nice Mistika project they use for GPU stress testing? Something similar to the Resolve Standard Candle Benchmark? Anything specific I should be looking for comparing the Quadro vs. dual 2080 TI?

I have downloaded various RED and Arri footage, some 8K 60fps. So I'll put those on the timeline and see what playback performance is as is and with some grades.
