Earlier this month Hardkernel announced the ODROID-C2 as a 64-bit ARM development board that would begin shipping in March. Fortunately, you don't need to wait until next month to find out how this $40 USD 64-bit ARM development board is performing: here are some benchmarks.
The ODROID-C2 is powered by an Amlogic S905 SoC that provides four Cortex-A53 cores and a Mali 450 graphics processor. The board has 2GB of onboard DDR3 RAM, HDMI 2.0, Gigabit Ethernet, four USB 2.0 ports, and an eMMC socket. It's not a bad little board for $40 USD that's ARM 64-bit and at least has 2GB of RAM, which is a much better bargain than the HiKey 1GB for $75 or HiKey 2GB for $99 USD. Of course, nothing like the speed though of the Jetson TX1 powered by Tegra X1 SoC.
