Goal is a new higher level cognitive robot architecture on top of ROS.; I'll post more about that soon (I have a bit up over on Researchgate). Mostly got this for research - want to compare it to the Xylinx Zinq ultrascale+ capabilities. (You get dual core RT on the Zinq, in addition to 4-core non-RT CPU plus the fabric; with the Xavier you get 8 cores with the 512 tesla core GPU. So I expect performance to differ depending on the algorithm, but mostly I'm interested in graph processing, not just ANNs... so will have to run my own benchmarks. Ultimate goal is a robot you don't program, but train as you might an assistant.
ODROID HC2/HC1 would be especially interesting for Massdrop since the primary use case is a big clustered filesystem - most folks interested would need to buy several. Should get the numbers up for a better discount.
Perhaps the better question is: What is your needs? More parallel threads? Faster CPU or onboard DSP for offloading DSP stuff? Serving web stuff? "More powerful" is a desire, but especially if it's going to end up battery powered, better consideration is what do you need to use it for.
I'm in the market for an Odroid XU4 right now. I want a firewall + adblocker (adblocker similar to pi-hole). Gigabit ethernet, fast EMMC for the OS, decent RAM for a SBC.
