Well, technically, it has a dual core CPU, but each core is pretty much the same as those ones[*]

. Meaning indexing is probably the one thing where it'll have a significant impact, but it's going to be much more subtle in day to day operation (hence the lack of marketing fanfare around that fact).

That said, it's definitely non-zero, the Kindle firmware is designed in a way that lends itself fairly well to parallelism, as far as these things go.

EDIT:[*] Scratch that, the i.MX7D is two A7, while the i.MX6SL(L) is one A9. So, not exactly the same CPU

. The A7 should be more power-efficient, at the expense of performance. Think low-power Intel notebook chips. Mainly a newer, finer process.
