It's recommend to change opcode frequency, yet the notable change is we use 4GB instead is 2GB.
In this case, what are the minimum requirements for CPU (intel) would be needed?
In discord I read that meros is initially focused for AMD CPU. Is that so?
The minimum CPU requirements do not change to the point of mention. The amount of RAM required increases, which is meant to disrupt certain GPUs, along with eventual FPGAs/ASICs.
RandomX does show an AMD bias, yet Meros does not focus either way.
