If a smartphone (when we switch to binary) can process 1000TPS, a RaspberryPi could also process 1000TPS, am I right? If this is not the case, we should look into the Odroid, if it is far superior to RPi.
Actually, Odroid-U3 is superior than most smartphones today. It has quad-core Samsung Exynos and 2Gb of RAM. I think it's more than enough for 1000 TPS.
