    The Cortex-A55 cores deliver up to twice the performance compared to Cortex-A53 in memory benchmarks, and a more typical 20 to 30% performance improvement for common tasks at the same frequency.

    Amlogic S905X3 has some optional features like the Neural Network Accelerator and a Cortex-M4 core for always-on processing, so we should expect several part numbers, but this was not detailed in the product brief.
