Finally, the problem is not OpenCV, but the way you are using it. I've wrote complex processing that takes 3ms on a mobile processors, and saw others do the same - the price is a hard work in optimization. Take this post as an introduction to a more serious approach to optimization. On Intel chips you have SSE instructions instead of the NEON technology found on ARM devices.

Coding in C gives zero advantage over C++, but it may give a boost over Python. The profiler will tell you exactly how much you can gain.
The difference between i7 and Atom is the expected difference between a top-end desktop processor ad and a modest, low-energy chip.
