>Power efficiency / performance-per-Watt tests were not conducted due to the remote ARM testing. Likewise, there isn't performance-per-dollar metrics due to many variables at play when it comes to factoring in the ARM and POWER9 costs.
That seems to make the benchmarks entirely useless for gauging Power performance for the server market. Not saying it didn’t fall behind its competitors (I’d be surprised if it didn’t given how much more AMD and ARM makers have been investing in chip development), but these benchmarks don’t tell us that.
