Most of the applications are heavily optimized for x86 processors for years. There are so many applications littered with intrinsics and x86 assembler coded blocks, algorithms are tuned for x86 and intel specific memory characteristics. Arm got some attention because of phones, but only in last few years.

Power8/9 are very decent processors with a lot of raw power, but it will take a more concentrated and long term effort to have a level playing field in the software landscape.
