As an alternative to the Raspberry Pi 3 for a low-cost 64-bit ARM (AArch64) development board is the PINE 64, which was successfully Kickstarted as a "$15 64-bit single board super computer" that generated more than 1.7 million dollars. The PINE 64 is still shipping out in limited quantities for now, but the folks behind this project were kind enough to send over a sample of their PINE 64 1GB SBC for some benchmarking.
The PINE 64 is powered by a 64-bit quad-core ARM Cortex-A53 processor running at 1.2GHz and the SoC has a Mali 400-MP2 graphics processor. The different PINE 64 models include the base $15 unit with 512MB of RAM, the PINE 64+ with 1GB RAM (what's being tested today) for $19 USD, and the PINE 64+ 2GB with 2GB of DDR3 for $29 USD. The PINE 64+ models also support a five megapixel camera port, 4 lanes MIPI video port, and a touch panel port. Another advantage of the PINE 64+ models over the $15 PINE 64 is Gigabit Ethernet rather than 10/100...
