x86 replacement?

@LMM  Thank you for your extensive answer and that you have done the benchmark. Well, over all it sounds not too bad and I guess it would be worth to give the RockPro a try. But I have to think about it a little more what to do...

Thank you again, it was really helpfull!

Be careful about depending on benchmarks which mostly sit inside the cache  and rarely reflect real world performance.
One metric that you can use is to compare the size of caches. Intel I7 is an expensive chip (> $300/-) with large caches 
and will easily beat a RK3399 (~$15/-) in real world performance- example running Firefox browser.

So if you are expecting I7 class performance you are likely to be disappointed -.
