What Hacker News says
5 sourcesDesigned to be CPU mined: https://github.com/tevador/RandomX
In Why MoneroMonero's PoW algorithm is RandomX [1], which is optimized for CPU mining. While it is possible to mine with GPUs, it is significantly slower and unprofitable.

In Ethereum just activated its ‘London’ hard forkMonero has more extensive ASIC-countermeasures in place: https://github.com/tevador/RandomX
In Police destroy Bitcoin miners with steamroller in MalaysiaGenerally yes. The RandomX dev seems to have some issues getting to to work well on apple silicon, however the Xmrig dev has it working, but seems it caps out at 2.3kh/s due to not being able to take advantage of JIT or large pages. (At least from what I read of their respective GitHub repos
https://github.com/tevador/RandomX/issues/196
And
https://github.com/xmrig/xmrig/issues/1991).
RandomX mining is better at the moment, but that may be because nobody's developed a GPU minter tailored to the uniqueness of apple's GPU, if that's even possible.
