I've started to replace all games played by Stockfish 6 and Komodo 9.2 with their most recent versions available for Android.
After first 50 games, Stockfish 121215 seems to compete much better than Stockfish 6 could.
A longer time frame between two Stockfish versions compared to Komodo's state, there's nothing unusual and unexpected here.
Anyway, we will soon find out how close they will rank. It's really hard to guess which will perform better and i'm sure even 300+ games will not be enough to assure a concrete verdict as long as the ELO difference remains narrower than the error margins.
Then, let's stay tuned for Rapidroid January-2016 while the two Exynos processors try to survive the quadcore torture running at 1.6 Ghz in my refrigerator!
