I loaded both the Raxda Debian OS and the Armbian OS on the Rock Pi 4A+ (4GB RAM / 32GB eMMC) integrated eMMC chip and both boot fine. I then ran the Phoronix pts/scikit-learn benchmark and got a big discrepancy in performance: https://openbenchmarking.org/result/2112285-NE-2112281NE08

 

The Raxda Debian OS (noted as rockpi4a+raxdadebian in the benchmark) performs basically the same as the Rock Pi 4A version (noted as rockpi4-rk3399 running Armbian), as expected. The Armbian OS (tested multiple times as rockpi4a-emmc, rockpi4a+, rockpi4a+governor, and rockpi4a+armbian) all perform terribly.

 

Thoughts?
