AE ray trace engine/CUDA GPU performance comparison

Danny Princz and I have been doing a series of tests using various nvidia graphics cards and After Effects new ray trace engine. It yielded some interesting results, particularly considering the possibility of an updated MacPro with a GTX600 series card.

The benchmark itself is a 6:12 render of an animated scene (made by Danny Princz) composed of no external textures, so GPU memory would not be a major factor in performance. CPU usage during renders is negligible, so it seems to be largely or even entirely CUDA processor dependent.

There's a link to the full datasheet at the bottom, but the most interesting finding is in this price to performance chart.

The lower number suggests a lesser value. Higher price/Lower render speed. Take away: don't buy a Quadro 4000 for the mac.

Secondary take away, the 600s are not a friend to CUDA processing. Best to pick up at GTX500 card while you can.
