Memory: 1GB DDR3 @480M

Raspberry Pi 3
CPU: 1.2GHz 64-bit quad-core ARMv8 CPU
GPU: VideoCore IV 3D graphics core
Memory: 1GB RAM

Sorry, I had posted thw CB4 specs before.
This seems slower or lower spec'd than a Raspberry Pi 3.
Assuming single core usage, the DDR3 will allow for much faster execution. It's an issue with Pi, they went for affordability for schoolkids, rather than "best possible" performance. Even with more cores, the PI does not run so fast, as each processor still has to read and write to comparatively slow memory.

You see this a lot on Pi forums. "Why isn't my Pi as quick as XYZ system". Answer is, it was built for affordability and flexibility, not raw performance. SDRAM is cheap, but it ain't that quick.

AROS on Pi sounds interesting, as does OS4 on PI. Real OS, not emulators.

Nice thread on the subject of PI Aros, including an attempt at a Walker;-
