It's because of the "silicon lottery", so to speak. Every single CPU is unique, every single motherboard is unique, every single memory module is unique, etc. You could build several identical systems and get several different results. Each CPU comes from a slightly different part of the "wafer" (a big disk that contains a large number of CPUs on it), and the same is true for all other chips.

Layout design of the motherboard effects the performance of the system. Some manufactures design for features, others for performance. The asrock of formula is a performance design, especially with oc in mind. This means the layout revolves around having the optimum trace runs, and power delivery at the highest priority... Also, the bios would also be more aggressively times.

In real world applications, you wouldn't notice much difference, but at the extremes, when every little bit counts and you look at all of the numbers, the little tweaks all start adding up.

Less to do with the silicon lottery (since these are stock clocks) or board layout than firmware differences that mandate different internal timings for memory and other aspects of the platform (though board layout can influence these things).

Some boards seem a lot faster in I/O performance.
