The Anandtech review found the GPU Compute performance to be lacking, below a 570 even.

Haven't seen a CUDA test yet but so far it looks like there is no "Magic Bullet" here.

i bet it really depends on the application how and what it does?

Curious how it will compare to the 3GB 580 card for MacPro use.

DaVinci 8.2 OSX 10.6.8
MacPro 12-core 5,1 2.66 Ghz
32GB RAM
RAID0 8TB Internal
Nvidia GT120/GTX470
BMD Extreme3D
HDlink3D DisplayPort
Dreamcolor/Panny VT25
Tangent Wave / Wacom

I find that weird. Being almost three times the CUDA cores compared to the GTX580.

Looking forward to see the 4GB version show up. Then I'm ordering asap.

i also think i would be fast even if some tests were not happy.

in the end it really depends how software is using it.

By mathematics it should burn hole in the paper on cuda numbers.
Imagine triple the amount. Mac's internal data lane would limit probably ;)

Can we slap this PCIe 3.0 card in a PCIe 2.0 slot and just get a peaked performance or will everything just explode?

I've ordered one to test. Yes pcie3.0 is backward compatible with pcie2.0 but I don't know if nvidia drivers will support 680 in Mac. Will let you know.

Really curious about this, as the power draw is 195W, which is great for non-cubix setup, where the amount of cards start to tax the mac pro power supply.

Comparing it to the the GTX 285, 205W & 240 Cuda cores, The GTX 680 is 195W & 1536 Cuda cores.

I'm very curious, but this might look like the new base card, (one that would slide in very nicely in the PC box I've slowly been build as well...).

What is the power draw / cuda core # on the 580 3GB card?

The official power draw under load for the 580 GTX 3GB is 244W, but some of the overclocked versions are even higher. I have the EVGA version.

Is the EVGA in your MacPro running Lion or in a cubix?

The Fermi cards ran the CUDA Cores at double core clock speed, the new Kepler cards use more cores but they run at regular clock speed. (ie, not doubled)

But they triple the number of cores... Isn't that better?

Currently, the GTX680 has wretched Compute performance.

Whether this is due to immature drivers, the lowered SM count, the half speed Shaders or the phase of the moon is unknown.

http://www.anandtech.com/show/5699/nvidia-geforce-gtx-680-review/17

We can just hope that the drivers mature and/or they release the GK110 which will mop the floor with current cards.

I will settle for OSX drivers for GTX680 for now. RIght now it is dead to the world in every iteration of OSX I have tried.

I don't think civilization 5 it's a parameter to take to evaluate 680 card with davinci
And for other way i don't think that nvidia guys are so stupid to make a next generation card worst than before generation
The only answer it's wait to davinci engeneers optimize the program for this card, and i presume windows version of davinci it's better than mac
