The Rpi 5 supposedly has the crypto instructions. See below:

Amazing that they finally quit being cheapskates and decided to pay for the crypto instruction extension that every other ARM producer in the world has included for the past 8 years already. I wonder what changed their minds.

So it’s another Broadcom chip quadcore with only 2MB L3 cache. I.e., only enough cache to run a single RandomX thread. The other cores will be wasted.

These have always been and continue to be worthless junk. For practical use these days you need closer to 4GB RAM per core, and of course 2MB cache per core. This thing only has enough resources to utilize 1 (core."

Although I have been able to compile Xmrig on my Rpi 4, none of your recent crypto builds worked.  I finally was able to purchase an Rpi 5 from Adafruit and will try again.

I have several Orange Pi 5 boards mining Verus coin.  I'll be able to check the Rpi 5 hashrate in comparison.

Apologies to the quoted Reddit user.  The post is 5 months old, and from a MoneroMiniing thread.  I have not done a thorough search to verify its validity.
