Wow Ray, that' fast!
You ask for predictions but less than one hour later, the outcome of 8/10 games is already revealed (and now 10/10!!)
But an interesting comparison. I would have guessed a more balanced result, as I have Chess Genius Android in my private list with 2490 CElo; and TKP with 2529, so about "only" 40 points above.
But in addition, my Android is an old Galaxy Tab 2, featuring 2 ARM Cortex A9 cores@1.01Ghz.
I can confirm Chess Genius only uses one core (so the performance gap is not so much to your Tab A8, apart from twice the Mhz) and I do agree it does not scale that well with more speed. Your results confirm!
Thanks for the games

Hi Tibono. Yes I initially thought the match would have been closer especially after the two draws at the start. Perhaps a match between Chess Genius Android and Chess Genius Millennium Element would be interesting, if not done already?

Your ELO difference between TKP and CG Android is very interesting and much lower than from my match. What time control did you use?

Ray

Hi Ray, 15secs per move. This is slightly in favor of the Chess Genius program, with regards to its mediocre scaling ability with both hardware performance and/or longer time controls.

Hi Eric, think I'll have to try another match with your time control just to witness what happens with my tablet. But with your rating of 2490 at 15 secs/move and my result (at 30/30 rest in 30 minutes) with an ELO difference of 375, this is an extraordinary difference.
