Raspberry Pi 3 and hardkernel ODROID-C2 launched the same day, and together with Pine A64/A64+, are the only ultra low cost (<$40) 64-bit ARM development boards available or soon-to-be available, so I’ve decided to make a comparison of the three boards the same way I did with ~$10 boards with a Raspberry Pi Zero, C.H.I.P, and Orange Pi One comparison.
I’ve used features of Pine A64+ instead of Pine A64 since features and price are closer to the other two boards. Text highlighted in green means a board is clearly better than the other two for a given features, while a red highlight means it’s the weakest of the three.

Monthly ODROID magazine
|Somewhat active Pine64 Forum, but frequency of post should increase once many of the 36,781 Kickstarter backers receive their board|
|Documentation, and hardware files.||Documentation is available via eLinux RPI Wiki, with little info about Raspberru Pi 3 specifically, but it’s not really an issue, as it’s software compatible with Raspberry Pi 2
Schematics are not available, even in PDF format, and the board hardware is closed source.
Broadcom BCM2837 datasheet is not available, however many of the peripherals will be similar to BCM2835 where the datasheet has been released.
|Documentation can be found on ODROID-C2 Wiki.
Schematics (PDF), autocad files, and Amlogic S905 datasheet are not available (yet), but those files were provided for ODROID-C1.
No PCB layout or Gerber files are provided for ODROID boards, so the board is also closed source.
|Documentation is available on Pine64 Wiki.
Schematics (PDF), and datasheet for all main chips including Allwinner A64 datasheet have been released.
PCB layout and Gerber files are not available, which makes the board closed source.
|Listed Price||$35||$40||$19 (1GB RAM) / $29 (2GB RAM) Kickstarter prices|
|Shipping to US address|| $7.99 via MCM Electronics
$6.75 on Ameridroid.
Total: $48.70 (Board price is $41.95)
Total: $26 or $36
|Distribution network and Availability||Wide sales network, with most online retailers and some brick and mortar shops selling Raspberry Pi boards. Good availability as the foundation produces 300,000 boards before launch||Available via Hardkernel, or distributors in US and Europe. Shipping may be costly to some other countries.||Currently not available, and it’s not clear which distributions channels will be used. Kickstarter backer s are starting to receive their boards.|
Since there’s quite a lot to go through, I may have made some mistakes, or missed some little known features, and corrections are welcome in the comments section. Please note that the prices for Pine A64 is likely to go up a little after the Kickstarter campaign.
Boards are likely to show similar performance in synthetic benchmark, except ODROID-C2 which should show a significant lead. However, I could not find benchmark for Pine A64 right now, and as we’ve seen this morning, Aarch64 improves performance significantly over Aarch32, so current benchmarks are likely to become invalid if/once Raspberry Pi 3 gets a 64-bit port. For example, Pine A64 is currently 15 times faster in sysbench CPU benchmark (prime numner computation) compared to Raspberry Pi 3, and it’s clearly not showing the true performance difference.
As usual there’s no board that is always better than the other two, and depending on your use case, technical ability, and other factors, one board may be better suited to you or your application.
