When it comes to dedicated ebook readers the technology evolves at a much slower pace than other forms of electronics.
With computers, tablets and phones there are tons of different processors and hardware components used among them.
But with ebook readers they all share some of the same components.
In fact all E Ink ereaders use the same processors from Freescale.
For the past 4 years all Kindles, Kobos, Nooks, and a number of other brands use the same exact i.MX6 processor.
A few Android-based ereaders use the dual-core version of that processor, but most ereaders use the solo version.
Back in June 2015, Freescale unveiled a newer i.MX7 line of processors with greatly improved power efficiency. But still to this day not a single ereader has been released with the newer processor.
Perhaps in 2017 we might finally start to see some new ereaders come out with i.MX7 chips, but so far there hasn’t been any indication of such.
It makes you wonder what’s the deal with the i.MX7 processors? Are they not a good option for ereaders? Freescale claims they are.
Unlike most “new” processors the i.MX7 doesn’t improve on speed. In fact it’s 200 MHz slower than the i.MX6, so maybe the slower speed isn’t a good fit for ereaders. The main improvement with i.MX7 is a big boost in power efficiency, and ereaders already excel in that regard so perhaps the benefits don’t outweigh the negatives. It might be better just to wait for the next round of “new” processors for E Ink, ones with improved efficiency and performance.
