The RK3399 dev board I posted earlier looks like a perfect board to test the RK3399 with
How about just going for this one then? Seems to have almost the same
http://www.orangepi.org/Orange Pi RK3399/
Currently $109... which seems pretty cheap to me
I struggled to parse that statement, but yes, it has a miniPCIe slot which can be used as with a modem (and there's a sim card slot on the board)that orangepi version seems to lack to gain an MiniPICe socket but loses a 3G/LTE socket (which looks remarkably like a MiniPCIe socket to me)
On the one hand mini PCIe actually has a different physical layout than M.2 B and M key (which are also incompatible to each other unless the card supports both!), on the other hand the original mini PCIe standard already defined multiple interfaces (PCIe and USB 2.0) of which none is mandatory. For example, the 2nd mini PCIe slot available in T60 Thinkpads that is supposed to be used for WWAN cards is USB only.The form factor looks to me like it's designed to take pre-M2 memory cards, but I guess other peripherals are available in that connector, so perhaps the hardware is the same even though the labelled uses vary.
Even better - and thank you for using spoiler tags!
[doublepost=1529421514,1529421138][/doublepost]If the RK3399 is really going to be considered - board availability seems high.
I think this is the same one @vcoleiro1 posted above.
@WizardStan - is this what you were looking for?
Four different versions with 2GB/4GB RAM and camera/nocamera, so they have those bits of contention covered.
Nice little case & setup. Looks power-on ready.
I still like the additional connectors on the board that @pmprog found better, but have no basis for preference beyond that.
[doublepost=1529422733][/doublepost]Is there a good way to compare the graphics performance of the RK3399 with the OMAP5432 and others?
The Pyra is multi-use, yes, but it has an obvious focus on gaming. Having accessible 3D drivers and high graphics performance should probably be a requirement - and may be more important than having "the fastest" CPU.
There are a few open source games that can tax a more advanced GPU than the Pandora has at least; games like OOlite and various 3D engines that run commerical game wads. But yeah, other than those exceptions, most things we'll be running on our Pyras are going to be CPU bound, not GPU.
There's a wide range of automotive SoCs for a lot of different purposes, including whole independent CPU architectures like Infineon's Tricore and Renesas' RH850 series - a lot of them are still single core. PowerPC Book E is also still alive and kicking in this area. Many don't have any sort of public information available, though - which often means that even the documentation that is not public is not necessarily complete or at least somewhat free from flaws... (this includes the R-Car chips)A modern automotive SoC will have several CPU cores, but much more emphasis on the GPU. It will be expected to drive fluid graphics on upwards 6+ displays simultaneously.

Please spare me with the 3rd gen R-Car series, I already had the... "privilege" to work with them. Some parts of their basic CPU design are seriously flawed.
But by far the worst are the fans on the V3M Eagle devkits - never ever have I seen such a crappy fan ever in my life, these things will drive you insane. They literally sound like one of the bearing balls might break loose at any time, flying across the room just to penetrate your skull at full speed - and that chip only has 2 A53 + 2 R7 cores.
It is 2 years old. We should be looking 1 to 2 years forward.The board I posted earlier is $164. I emailed them for a price
