Nvidia GTX 285 vs FX4800
Hi DaVinci forum
so the new resolve for Mac will need to use the Nvidia GTX 285 which is great cos I already have that card, but curious if performance would be greater or better with the FX4800, if so I would get that card instead, or will performance be the same with either card, the FX 4800 is 3 times the price of the GTX 285, but if it performs just a bit better I would get the FX instead.
if it is better, how exactly is that, faster rendering?
thanks

From what I hear the GTX285 is getting better performance…can let you know more when I’ve tested the system myself

I don’t yet have any direct comparison experience between the 2 cards. But looking at the specs, the 285 has more CUDA cores (240 vs 192) and twice the memory bandwidth. If I had to guess, I would guess the 285 will have better performance in the Mac than the 4800 would.

Hi Dwaine
thanks for the response and great to see you here.

I was under the impression talking to the Blackmagic reps at the NAB show that the DaVinci required a short list of Nvidia Quadro cards.

The linux systems require the NVidia S4 rackmount GPUs
OSX systems, as I said previously in this thread, have proven to work better on the GTX285 than the 4800. Its currently second hand info from NAB, we’ll be testing this asap

It was a GTX285 in the demo machine with the Wave panel, btw. It was very much RT with the DPX media in the demo, and I thought I saw more than 4 nodes on a lot of those shots too.

Wait, I’m confused. Isn’t the GTX285 1/3 the price of the Quadro FX 4800?

I have heard rumor that the DaVinci Resolve on Mac will require 2 video cards? Is this the case or can you run with just a single GTX 285 running multiple monitors and the Resolve CUDA computations? Would it help to add a 8800GT to the mix with the GTX 285 and still run your monitors off the GTX 285 for better all around gfx performance in other apps? My system currently doesn’t support the GTX 285 as it is a Mac Pro 2,1….however I have discovered that you can install a PC based GTX 285 in the primary slot with an 8800GT assisting in the next slot. Then through a injection process of some code have a fully working 8800GT and GTX 285. The CUDA performance benchmarks on that setup look really promising. I’m hoping I can use this method to not be forced to upgrade my 2007 Mac Pro Octo (8 3Ghz CPUs). Either way it would be nice to only have to run one video card and not use up another slot.

I suspect the main is used as the GPU and the UI is run off the 2nd
all our macpro’s currently run 8800’s so am looking what comes out top for Resolve also plus if the 8800 is useful as the 2nd or not.
Please let us know your findings Jamie.

It’s been explained elsewhere that the GTX285 must run without monitors attached, and the 2nd card runs the desktops/GUI. I do not know where I read this, but I’m pretty sure it was a posting by a BM rep here on CC.
The two remaining slots would ostensibly then be a RAID card and a Decklink.
As I understand it, the demo machine I played with at NAB had this setup.
