One the one hand, an 8 core ARM chip with all E cores interests me from a "maybe this can be passively cooled, but have enough horsepower to be useful" standpoint.

On the other hand, looks like it's made on a 22nm process, so while cost will hopefully be low, power savings will be limited.

On the third hand, the A55 is a 2017 core, and I'm getting really tired of ARM's strategy of dribbling out designs at an absolutely glacial pace to the lower end of the market.

Never heard of the Banana Pi, very cool.
