According to Scott Lurndal <
slp53@pacbell.net>:
The pressure against x86-64 is that one needs comparably expensive CPU >>cores to get decent performance, whereas ARM and RISC-V can perform >>acceptably on cheaper cores.
Are they cheaper? There are a lot of sunk costs already absorbed
by the x86-64 family both at Intel and AMD.
Amazon AWS offers both x86 servers and ARM servers, with largely the same
set of linux or BSD software available on each. The ARM servers are
somewhat cheaper.
The ARMs are their own Graviton designs, x86 are Intel Xeon and AMD EPYC.
Google also has their own ARM chips, haven't looked at them yet.
