ARM vs x86 vs RISC-V makes very little difference in power efficiency of servers. Cooling efficiency and efficiency of power distribution circuits are some of the biggest impacts on energy usage. The most energy-efficient datacenters today use liquid cooling vats for their computers, which are much more efficient than air cooling but come with tons of other problems.
