(Of course= better would be the 7000 or 8000 series Armadas which have full-fledged SR= -IOV on their SOC, but hey there is always room for improvement in the futu= re.) There is also the ESPRESSObin's baby brother (with fewer Ethernet ports): = the new Sheeva64 in wall-wart form-factor, continuing the venerable SheevaP= lug family. https://www.GlobalscaleTechnologies.com/p-86-sheeva64.aspx What is nice about the ESPRESSObin and Sheeva is that they are embrace Yoct= o-Project Linux, so you are not tied to any one Linux distro. Instead, Yoc= to Project requires that you roll your own Linux distro from near-scratch (= e.g., mimicking whichever distro or bleeding edge referent* that you prefer= ). * e.g., Linus Torvold's git repository https://www.YoctoProject.org Each ARM hobbyist SBC community has a different specialty. I wouldn't do h= igh-packet-rate telecom/datacom processing on a Raspberry Pi, for example. = That is what the Marvell Armada line is better suited for. Btw, Marvell's Armada series is the decscendent whose ancestors include the= DEC StrongARM and the Intel XScale, so in some ways this is one of the =E2= =80=9Cmain trunks=E2=80=9D in the ARM-processor community, especially for i= ndustrial usage=E2=80=93not some twig on a branch. https://www.TheRegister.co.uk/2006/06/27/intel_sells_xscale Plus, Marvell's MoChi (modular chip multi-die SOCs) technology (=E2=80=A2no= t=E2=80=A2 in the Armada 3720) is one of the industry leaders in DARPA's Mo= Chi endeavors in recent years. DARPA is trying to seed some of the major S= OC processor manufacturers with MoChi. Getting on board with Marvell now l= ikely prepares you for the aggressive MoChi future as the 1st-generation-Mo= Chi 7000 and 8000 series eventually migrates into the hobbyist SBCs, and th= en aggressive-MoChi successors follow after that in coming years. https://www.marvell.com/architecture/mochi
