Sounds promising. Just curious, how does the power consumption of the RK3288 compare to the A20?
don't know yet, but the PMIC does 3A @ 1V (!!) for the CPU and the same amount for the GPU (!).
it'll almost certainly have to be down-clocked to 1ghz, or a special cpufreq arrangement to be made where 2 cores are allowed to run up to the maximum 1.8ghz and the other two are capped at say 400mhz or less, something like that.
it's a 4-core 28nm where the A20 was a 2-core 40nm, so that's a 1/2 power-saving factor... running at 1ghz should be a roughly equal power consumption.... but the RK3288 is an A17, the A20 is an A7.
just have to see how it goes, basically.
