The Quadro 4000 can be Gui +GPU Power ?

[Rémi Berge]

you can use a Quadro 4000 (or 285) for GUI and GPU
you can use a Quadro 4000 (or 285) and quadro as GUI 4000 (or 285) as the GPU.
with a single card, the machine is slower.
if you need a good graphic card (GUI) for other applicalions, you can effectively replace the GT120 by more powerful.

according to the Mac PDF guide the 285 cannot be GUI …

But my question is :

is 4000+285 or 4000+4000 (on a macpro tower (no cubix) more powerful (more nodes of correction in realtime ) than 285 + 120 (or 4000+120) ?

thanks

excuse
the answer is no, the resolve will use for the processing the only
Card considered as the GPU.
Otherwise I confirm that resolve also works with a single Card GPU + GUI.(4000 or 285)

thanks remi

so to make sure I understood :
on a dual card configuration :the 4000 if used as GUI does not provide any extra GPU power (so it’s like having a GT120 )

ps:do you work for blackmagic ?

thanks

While you can use a single card (a 4000 for instance) for both the GUI and GPU, the performance will be much worse than using a separate card for each, which is why we don’t recommend doing that. In fact, we recommend you DON’T do that. But it’s your machine, you can do whatever you want. Just be aware of the consequences to performance.

Using 2 4000 cards, one for the GUI and one for the GPU, will not give you any better GPU performance than using a single 4000 GPU and any other card for the GUI. Using a second 4000 card for the GUI should make the GUI more responsive than say a GT-120, but it won’t improve the GPU performance.

you have understood well, despite my very bad English.
no I do not work for them, at least I’m not paid. 😉

Hey Gabriele,

it’s more like this :
You use two cards and have to decide which one will do the processing .
Only the secondary will do it.
You use only one and force Resolve to do both on one .
You will take a 25% percent performance hit but gain the power for Smoke, Premiere , Maya or anything else .

got thanks all .

that’s honestly what I thought ,but than I read that post on reducer that confused me (basically saying that 2x 4000 would give more GPU power than 120+4000)

but it is not

ps:using the cubix :doubling the numbers or GPU card ,dies double the number or realtime nodes ?
or is a % increment ?

at the moment I have 120+285 ,and I get around 8nodes with blur on HD DPX …if I add another 285 (cubix) will I get 16 nodes ? or less ?

thanks

The 285 ( I have only 1) works fine both as gui and gpu om my system.

I have single gtx480 driving 2 monitors and doing cuda processing. But it’s hackintosh. On a Mac pro you can try gtx470 from macvidcards. It’s the most powerful card you can put into your Mac pro. (they have 480 as well, but it needs external power supply)
