If you can point me to a benchmarking application, I'll try to run it on the RoboRIO. If you want another comparison between the old & the new, please see this (slide 9). I ran the same test on a 2012 i7 and it was getting 200+ FPS at 640x480 so I took it out of the comparison. Also, please note this was only using one of the two RoboRIO cores.

Side note, from what I've learned at NI Days, the new RIOs have two task schedulers. One is for RT, one is for non-RT.

I recommend reading over the Introduction to NI Linux Real-Time.
