NVIDIA vs AMD: GPGPU performance

Question

I\'d like to hear from people with experience of coding for both. Myself, I only have experience with NVIDIA.

NVIDIA CUDA seems to be a lot more popular than the competi

Answer 1

Cuda is certainly popular than OpenCL as of today, as it was released 3 or 4 years before OpenCL. Since OpenCL been has released, Nvidia has not contributed much for the language as they concentrate much on CUDA. They have not even released openCL 1.2 version for any driver.

As far as heterogenous computing as well as hand held devices as concerned OpenCl will surely gain more popularity in near future. As of now biggest contributor to OpenCL is AMD, It's visible on their site.
