ODROID-XU4: Much Better Performance Than The Raspberry Pi Plus USB3 & Gigabit Ethernet @ $60
Next up is a look at the performance-per-dollar based on the current pricing in the US for these different boards... Keep in mind the Jetson boards are much more expensive but particularly useful for GPU computing that wasn't the focus on this testing due to predominantly testing the low-end ARM SBCs in this article.
The ODROID-XU4 at ~$62 offered great value and was generally delivering the leading performance-per-dollar except in some cases the $25 Raspberry Pi 3 Model A+ coming out ahead... But there you also have much less RAM, no USB 3.0, and no Gigabit Ethernet.
So ~$60 is quite competitive pricing for this single board computer from Hardkernel.
