Hey guys need some suggestion...
What is the benefit of nvidia CUDA cores over software rendering in applications like after effects and premier pro and other cuda supported apps...

So pls some experienced person using nvidia cards for rendering give me some suggestions...

I have a i5 2500k OCed CPU ...

its just one form of converter techniques which green party offers ! now a days even red party is offering some thing call amd app as cuda from nvidia ! go for any ! they help in getting better encoding and better rendered outputs :D
 
When you encode movies from one format to another, a lot of processing power is needed. when this processing is offloaded to gpu, it takes a lot less time to do it.

I stopped ripping movies for a long time but here is my experience; a typical 2.3o hour movie encoding from dvd to h264 at around 800kbps takes anywhere around 12-20 hours using all the advanced settings of x264 (2pass) on a amd phenom quadcore 2.2ghz processor. that same stuff would take around 1 hour on a ATI Radeon 3870X2.

The latest core i5 3rd gen processors have an onboard gpu, so if your processor is 3rd gen, the encoding is automatically offloaded to gpu.
 
Software rendering is done by serial processor as in cpu, whereas hardware accelerated rendering(CUDA) is done by parallel processor like gpu.

CUDA rendering >>> CPU rendering in terms of speed.
Today cpu's packs a max of 4-8 cores whereas gpu i.e. gtx 780 packs 2304 cuda cores so rendering speeds is many times faster in the later one due to increased number of processors doing the job.

This is the same reason why nvidia excelled back in 2006 because they focused on this aspect.

Hope this helps :)
 
isn't CUDA also software developed by nvidia to support parallelism in their GPU hardware to increase the performance?
 
Thanks guys for helping. ...
Gtx 460/550 Ti has anyone been using these for gpu acceleration in after effects/premier pro/photoshop/3ds max /maya ....please share your views
 
Premiere Pro CC now supports OpenCL acceleration. Considering how badly the 7970 humiliates even the GTX Titan in GPGPU applications, you are better off with an AMD card.

I've tried luxrender with OpenCL on my 7970. The performance improvement over pure CPU based rendering is roughly 10x. I also dabble in OpenCL as a hobby. The bitter truth is the performance improvement with a GPU completely depends upon how well your app's OpenCL kernel is optimized for parallelism. Some do a really good job, some not so much.

As for CUDA, its pretty much dead in the water. Everyone is moving to OpenCL.
 
But after effects still use CUDA for rendering bro.... which is very slow off the cpu only....
Looking now for a decent Nvidia card only...
