As much ram as possible.
Plenty of CPU power would be nice.
A good storage interface (in order of preference SATA is better than
USB3 which is better than USB2).
Support in Debian kernels would be nice.
arm64 support would be nice.
This is what we've all been waiting for for years.
Indeed. I figured I probablly wasn't the only person on this list
waiting for such a thing and hence I put out this message asking if
anyone had spotted something I hadn't. I also asked on irc.
Currently looking at the cubox i4x4. Anyone have any other suggestions?
No, they're all deficient in some way.
That one (a) has a Freescale processor, which I would avoid after
my experience with the i.MX53,
mmm, I did have a nitrogen6x die on me (out of warranty and given where
I live sending it back to boundary for an opinion on why it failed and
whether it was repairable would have been prohibitively expensive).
Other than that i've been pretty happy with imx6 based stuff.
(b) isn't 64-bit, (c) has only 1 GHz
CPU clock.
You can get faster CPUs (4x 2GHz A15, so probably about 3X the
speed) but half the RAM and no SATA (but USB3) in the ODROID-XU4.
Yeah, that is pretty much my conclusion. For the ammount of money I'm
prepared to spend on arm boards you can get modern CPU cores of 4GB of
ram but not both. Theres the nvidia jetson TX1 but it costs far more
than I personally consider reasonable (though I would note that sili and
i'm not sure what the kernel situation with it is (it apparently has
some support in mainline but I dunno if it has enough to be usable).
Theres the husky/cello (which is overbudget but good enough specs that I
would consider blowing said budget) but afaict it's not actually
available yet.
If you want 64-bit, the ODROID-C2 which I have is possibly
the best option - but it has A53 not A57 cores (so maybe 2X
the speed of the Cubox 4x4), and 2 GB RAM, and no SATA.
The question of whether CPU, RAM or filesystem I/O limits
performance in practice is an interesting one. The feeling
I have is the for kernel compiles my ODROID-C2 is CPU-limited.
The thing with ram is that most of the time it doesn't matter much but
when it does matter it really matters. Grinding swap sucks.
Let us know what you decide.
If noone suggests anything better by the end of today I think i'll go
ahead and order the cubox i4x4
