(3D rendering) Can I upgrade to GTX1080ti?

[leoletsrock]

This upgrade is not for gaming

Hey guys,

I need a CUDA card to do architecture GPU rendering, wanna ask if my current hardware is compatible if only change the display card to GTX1080ti.

All advises are welcome!!

Thanks
Leo

Yes your system will work fine with a 1080ti-just make sure you have an adequate PSU to power it.

Thanks Greek0!

From the purest sense of can you put this card in, and it work on that hardware? Yes.
As said above, proper PSU and to add correct space in the case, it should power up and work.

Now, will you see some massive improvement? Based on your current card, yes...however I think it important to note that you would likely see very similar end results from a much lower level of GPU paired with that CPU. Unless you are soon planning a massive system upgrade I wouldn't spend for that card on the current. Personally think you would do very well on the 1060 or 570/80 level cards for that purpose....even without a firm understanding of the processes you are working.

You are so right and I do have the same concern - will the improvement obvious if I use old CPU + powerful GPU. The reason for buying a CUDA card is to speed up the rendering process, for detail please see below link (More CUDA, more fast)

I think Im not going for 1060/1070, because my plan B is if improvement is not obvious, then I will do a full upgrade.

What'd you say about the RTX? Do you think its worth waiting and spending for "next generation" card, for GPU rendering? So far info shows it has less CUDA core, is there much different between DDR5 & DDR6?

Is the PSU seems ok for the new card?

Checked online 1080ti requires less wattage than R9 290, is this how i check the PSU?

GPU base rendered don't need fast CPU for sole rendering, but fast CPU does make viewport more fluid, and loads scenes quicker, however, the downside of your platform is the interconnection, which may bottlenecking on saving large files, so if you eventually install GTX 1080Ti make sure you also get fast PCIe M.2 storage (PCIe X4 such as intel 750 HHHL)

If it can run a R9 290 fine at the moment, then it should be fine for a 1080 ti.

I would still check and make sure its good quality bearing in mind the cost of the 1080 ti and not wanting to blow it with a crap psu.

There're two kind of GPU render engine, CUDA and OpenCL, if your render engine is specific to nvidia CUDA (octane, redshift, v-ray) then you must use nvidia card. If you use Luxrender or Radeon Pro Render then you can use Radeon card.
Normally it'll run faster on higher stream processor (Radeon) or Cuda core (GTX or Quadro), so 3580 CUDA of GTX 1080Ti performs better than 2560 GTX 1080, you'll notice the render completion difference on large complex scene.

I notice a 40 sec difference between octane and cycle or corona on a same file, so GPU render is faster.
