Indeed, 128 EPYC cores in 2 sockets (with total 16 memory channels) will give a lot of power. I guess it's worth mentioning that the 64-core chips have much lower clock rate than 16/32 core ones though. And with some expensive software that's licensed by CPU core (Oracle), you'd want faster cores, but possibly pay a higher NUMA price when going with a single 4 or 8 sockets machine for your "sacred monolith".
