new entry is a water resistant Lenovo A660 with 2 core cpu 2x 1Ghz.
In opposite e.g. to the sony xperia go it has a 4" Display 800x480 screen resolution that makes sense. dual sim card slots. micro sd card slot. you can exchange the battery.

- Samsung Galaxy note 8 which I believe should provide the same nps than the galaxy note 2
- Toshiba Excite Pro which is the first tablet available to use the Tegra 4
I like small devices so if the Excite Pro is "only" 2 times faster than the Tegra 3 which is my understanding, it should have nps around 900k which is only 26% better than the Galaxy note 2/8 which uses th Exynos 4412.
The Exynos 4412 seems really good for chess
have you tested the excite pro yet? I'm curious to know what the tegra 4 can do.
it run with Android 4.2.2
it's a Rockchip RK3188 4core @1.6Ghz
One important thing..when you use 4cores it runs at 4 x 1.2Ghz!
I had also a Pipo m9 Pro..who has a higher resolution..but i don't see the difference with my normal m9 ..it has 32Gb normal m9 has 16Gb
it has GPS ,m9 no GPS
But most important..it's much slower for chess!! 447K
the reason i think are..they have same cpu..but pro higher resolution ,need more cpu/gpu power and maybe because i had directly from the first days it came out..i was in China..with a new firmware update it can works better?
Before i sell it..i show there was a new update firmware..didn't update ,because was in Chinese..
I had also test a Voyo A15 Exynos 5250 11.6" IPS 2core @2.0Ghz
And this is a very fast tablet..when you use single or dual core applications it's much faster then Pipo..but again for chess was pipo faster because he has 4cores..i would like to see this Exynos 5250 running with 4cores..then i buy directly!
The most interesting bench is the Mediatek Cortex A7 quadcore 1.2ghz result at 493knps! That makes it much faster than 1.5ghz Cortex A9! Interesting because A7 is supposed to be a budget low power in-order CPU. It seems here that chess doesn't benefit much from Out-of-order execution but rather from bigger caches and shorter pipeline stages(fewer branch miss predictions?).

it seems the mediathek cpus are better for chess then the qualcom cpus used in many top mobiles. you see the benchmark of the lenovo a660 ?
it has only 2 cores x 1 Ghz !! the most qualcom cpus use 1.5 Ghz per core.
What seems like a fairy tale today may be reality tomorrow.
Here we have a fairy tale of the day after tomorrow....

Though it's also made by Mediatek, the CPU inside Lenovo a660 is dual core cortex A9 rather than the lower end A7. Thats why its result scales about equal to Galaxy s2 with thesame dual cortex A9 but clocked a little higher. What's interesting is that the Cortex A7 has higher result than A9 if you scale results at the same clock!
Good news is that Mediatek is going to release 8-cores of A7 that can fire all 8-cores together unlike the Big.Little configuration. It will be the new king for mobile chess I think.
