performance - OpenCV gpu perfomance -

I do not have a modern NiWidia GPU card, but before buying a new card, there is a need to make precise estimations for the stereo matching algorithm in OpenCV. I <<>

Is your post here Can the result be?

The OpenCV developer describes each week. It is quite long, but you'll get a description of algorithms, their performance, etc. You will know how fast the GPU is compared to the CPU. Of course, it depends on the images, algorithms, GPU quality and so on. But you will get an idea.

A small and very anticipated answer is that the CPU is ~ 10x faster than the CPU
