There are a few other reasons why ARM is popular in data center tasks, including those that are targeted at performance. The easiest to explain is vcpus.
On AMD/Intel, 1 vcpu = 1 hyperthread (to oversimplify, 1/2 core)
On ARM, 1 vcpu = 1 core
Even if the ARM system is only 80% as fast on a per-core basis, having twice the core count on a similar class instance makes the overall cost much lower.
