Which benchmarks did you look at, cause I have mine overclocked 
past 4 GHz.

Not faster than my desktop where it counts, at least for me (the 
gpu). Nothing really needs that much more power for CPU, and 
single thread performance hasn't gone up that much.

Don't think it would compare in terms of performance. As even 
that new fancy ipad pro CPU isn't anywhere near a current-day 
desktop CPU.
