@Proton2:I may not understand what it means to have 14nm features, but I'm pretty sure that it means that's the smallest discrete thing that can be printed on the chip.  It doesn't mean the path of the instruction is 14nm in total.  It does mean, though, that the instruction path can be shorter overall.

If you look at the visual layout of a modern CPU, you'll see literal centimeters between the processor and the cache, so you'll never get faster than that.
