GTX 480 and Resolve

[Tim Sutherland]

I am a little overdue in posting this, but just wanted to post my findings with a flashed GTX 480 from macvidcards on eBay in my Cubix expander. I have a rocket and the 480 in the Cubix, and I can get 14 nodes at half res premium or 7 nodes in 4k debater all with blur, qualifier, track, anything I can throw at it, in REAL TIME.

The 480 requires more power and an 8 pin power plug so it isn't ideal in a Mac pro tower, but in the Cubix it just screams. I can't say how great Macvidcards has been, even exchanged a previous card I bought from him for the 480. He writes his own firmware, and it just works, all I had to do was install cuda and quadro drivers, and replace one .kext file (easy) and all is fine. In my pci system info it currently says no info, but I think I just need to try a different slot, but all cards are working flawlessly.

This card made resolve go from good to fantastic for me. At around $500, it's a great deal for awesome performance, especially if you have a Cubix or hack.

Wow. That's great news. Please can you post some NR (noise reduction) figures? I'm having issues with NR and my 480 (but on hackintosh). I'm building a mac-pro/cubix system in the next couple of weeks and if everything (NR specifically) is working well for you I will probably get 2x 480's or 2x470's in the Cubix.

Thanks for posting!

I am not sure if NR is ever working realtime in Resolve. I saw a Linux system at Media Village running with I think 4 x GTX580's and it did not do well with NR either. It did however play 42 nodes with image blur just fine!

NR should be possible in realtime, it's CUDA just likt the CC tools. Also, others seem to be getting realtime;

Can you please test and let me know what figures you get?

Thanks,

glad you're having no issues, i was planning to pick up either a cyclone on cubix (cyclone is officially on BM's official config list now) and was gonna get 2 flashed 470's. I wish the form factor was better with the cubix, id' like to actually have it rackmounted, but the cubix rackmount versions are so overkill.

With NR I get 19 frames, even if I add other nodes. Macvidcards said that the 470 will be significantly slower than the 480, which sounds right to me since I never got anywhere near this performance with a 285.

Basically I never see the fps go below 24 unless I do NR.

interesting since the 480 really doesn't have that many more cuda cores than the 470. it's like a 30 cuda core difference, maybe clock speeds matter too. i'm a few months off from buying anyway. maybe they'll have flashed 580's by than. they won't be as loud that's for sure :)

Is a 6-pin to 8-pin cable a bad choice here? Will it fry the power supply/MB in my Mac 3,1?

You could probably get away with it if it were your only gpu, but if you are going to run 2 I would be wary.
