  GTX 260 v GTX 285

  Posted by Jonathon Lee on December 28, 2010 at 1:38 am

  I’m putting together my starter OS X Resolve. Have the GT120 for the GUI. Not using CUBIX yet…

  Has anyone tried using a GTX 260 in a 2009 Mac Pro? I just need something to get it running OK. Has anyone compared the performance of the two cards?

  Nvidia site says:

  GTX 260:
  192 CUDA cores
  Memory Bandwidth 111.9 GB/s

  GTX 285:
  240 CUDA cores
  Memory Bandwidth 159 GB/s

  FX 4800
  192 CUDA cores
  Memory Bandwidth 76.8 GB/s

  Quadro 4000
  256 CUDA cores
  Memory Bandwidth 89.9 GB/s

  I know some of these cards have different technologies.. DDR5 v DDR3, Fermi, different versions of CUDA chips, etc… BUT does memory bandwidth speak for it’s self? Is it just the number of CUDA cores or is it the “type” of CUDA core? Not exactly sure what “Fermi” means?

  Any insight is greatly appreciated.

  thanks!

  Great question been wondering about these specifics myself, hopefully someone can shed light!

  From what i have read here it seems that without a Cubix the fastest setup is the 120/285 combo – a further more in depth explanation of how these cards differ and why would be great.

  I’m using a flashed for Mac gtx 260 plus a 120 to drive the monitors in a 2010 2,66 ghz 12 procs, and it’s working really well. I bought the 260 while waiting for the fx4000 to came out as a cheaper alternative to the 285, but At the moment I’m sticking with the 260 as is working fine for my line of work, episodic TV shot in HD plus some Red work.

  What frame rates you get ?

  I get 24 – 25 fps on my 4000 with prorez HD on playback.
  With few blur nodes it slows down frame or two.

  Machine is 2010 12 cored 2.93GHz mac pro.
  Tracing is amazing fast.

  I usually get renders of 29 or 30 with 5 or 6 nodes with prores originated material, I’m using an internal raid with 3 disks.
  While grading I’ve not encountered problems with playback speed during real sessions using HD prores material. Sometimes the clip starts playing at 23 fps but after one second or so goes up to 25 fps and stays there, even with fairly complex grades of 8 to 10 nodes and with a few blurred qualifiers.

  sorry for my cluelessness:
  jorge:
  can i have a gtx 260 and an ati radeon hd 5870 in the same mac u have?
  did u have to solder a new (bigger) rom on the 260 to flash it with the mac rom?
  what maker is the 260 (besides nvidia)?
  tx for the info!
