When comparing the intel and arm architectures, GHz doesn't mean much. Transistor technology has evolved to a point where most processors are clocked in that area. The reason that the intel processor is so much faster is that with a higher power envelope, you can have extra transistors. There transistors can be used to have better branch prediction, have better prefetching, have better SIMD instructions and have more cache. This is what really impacts performance. If you compare the performance per watt of both processors you see that they are somewhat similar. Keep in mind that ARM processors are also made to be much cheaper than their intel counterparts. Both ARM and Intel do a stellar job in their respective markets.
