here's performance numbers between the 7950x, a modern dual-socket intel
server, and a POWER9:
https://openbenchmarking.org/vs/Processor/2%20x%20Intel%20Xeon%20Platinum%208380,AMD%20Ryzen%209%207950X%2016-Core,POWER9%2044-Core

as you can see, some tests (presumably more single-threaded) give the 7950x
a approximately 2x advantage over both the POWER9 and intel server.

I don't have cloud price numbers right now...
