Nvidia Geforce 520M vs 540M for OpenCV

I am planning to buy a new laptop and I am hesitating about the video card of the system. I know that Geforce 540M has a bigger computational power than 520M but is it important from the point of view of OpenCV? First I would like to use it for simpler tasks (color detection, line following) but later I plan to take some tries with CUDA, stereo imaging, Kalman filter, ...

Any ideas? Thanks

I guess that the one which is better for CUDA will be better for OpenCV. So try to find CUDA benchmarks about those two cards. Then you have to think if the performance difference between the two is worth the price difference.

Based on OpenCV's GPU accelerated computer vision page it seems that generally all OpenCV computations are done with CPU except CUDA calculations. So for everyday OpenCV use the video card does not matter.

However "The OpenCV GPU module includes utility functions, low-level vision primitives, and high-level algorithms. The utility functions and low-level primitives provide a powerful infrastructure for developing fast vision algorithms taking advantage of GPU whereas the high-level functionality includes some state-of-the-art algorithms (such as stereo correspondence, face and people detectors, and others) ready to be used by the application developers."

I would look at 600 family if i where you. It is in the same price range for some reason, but 3 times the cuda cores. I am the owner of a msi gtx 650 and with 384 cuda cores it has the same number as 560 ti. You are looking for a laptop card I would go with a 640M.

In fact I have already bought a laptop with 630M, it has similar perfomance than the 540M.

That is good as well, I might have gone for the 640M with 384 cores, but it is good that you got the 600 series it with the Kepler.
