Due to the impacts of the coronavirus outbreak, we are experiencing longer than normal lead times on certain products. We encourage back-ordering out-of-stock items to receive them as soon as possible.
We run several SBCs through their paces and compare their performances.
Benchmarking is a favorite pastime among many computer enthusiasts. Many tests exist that evaluate various performance aspects of computers, and with the rise in popularity of single board computers (SBCs), we would like to have a method of comparing them to each other.
Testing SBCs is nothing new. However, we wanted to create a set of (somewhat) standardized tests that we can apply to new SparkFun SBCs. We just want to get a comparison of relative performance; our tests do not have to be super accurate, but should show how SBCs perform against each other in the same aspects.
The Phoronix Test Suite provides a useful set of tests, and we chose only a few to construct our array of tests. Additionally, since power is a common concern among SBC users, we measured average current draw for idle and loaded CPU states.

If you are still here, then we can happily give you a summary of that report. We tested the following single board computers:
Each of the tests are briefly described in their respective sections below.
Note that the BeagleBone Black Rev C test was slightly different, as we had to use a 512 MB test file (instead of the 2 GB file used for the other tests). There was simply not enough space on the BeagleBone Black's onboard eMMC.
Note that we left out the Edison as it does not have a video out port and therefore no default GUI.
Compute average power consumption based on measured current draw (averaged over 10 seconds) and measured DC voltage. We created a current logging device to measure the instantaneous current draw. The raw test results can be found here.
So, you might ask, which single board computer is the best? Well, that really depends on how you plan to use it. If you want a lightweight server that consumes little power, low power might be your biggest concern (an Edison could be a good choice). Alternatively, if you want a tiny home theater PC, graphics is important to note (in which case, a pcDuino3 or Raspberry Pi 2 would be good options).
Personally, I am still a big fan of the Edison, especially when you consider performance per Watt (in CPU, RAM, and flash memory read/write). If I need some kind of video output, well, that's another story...
We plan to update the SBC Benchmarks tutorial once in a while with a new set of computers (hence the idea of "rounds"). If you are curious about how SBCs perform, definitely keep an eye on that page.
What SBC is your favorite to use right now (if you use them at all)? Are there other tests that you would like to see performed?
