"As one would expect, general usage is reported as being much snappier on the new AMD platform compared to the aging Atom E3950 solution"
The article mentioned it was to be expected that AMD would perform better.
The article also mentioned that "dropping the Intel Atom E3950 CPU in favor of an AMD Ryzen solution [...] has resulted in
surprising performance gains", as I'm sure I've already quoted earlier.
I don't know about you, but I don't normally expect people to be surprised at something they expected. Unless they expected something surprising, that is. But that's to be expected, unsurprisingly.
