Hi Rafael,

That's as fast as ARMv7 will ever get, I believe. I'm using Chromebook
2's quad-A15+2GB and it's about the same speed. Qualcomm's IFC6410 are
meant to be as fast as Chr2s, but the kernel is currently not
scheduling frequency due to power management failure.

On the AArch64 side, Chris is right that the options are far better!
Cavium's offering may be fast, but are not available yet. And when
they do, they're going to be *very* expensive.

Junos are fast-ish, AMDs are faster but the APMs are the fastest
boards you can buy today, and you can run on AArch32 mode and build
ARMv7 binaries with it. Though, you'll have to shell out a couple
thousand dollars for it.

If this is for personal use, I'd stick to either the Chromebook2 or
the Snapdragon (or the NVidia). If you need a bit more oomph and
stability, APMs are the ones to go.

cheers,
