Most of that is almost certainly the SSD.  It makes a huge difference
to anything that does IO.  I did add an SSD to my 6 year old laptop and
wow did that make a difference.  Did the clock rate change a lot between
those two i5 machines?  Also a few i5 models in the past were only dual
core rather than quad core.  Most (if not all) 8th gen are 6 core.
A quick check of some cpu speed benchmarks between 3rd and 8th gen shows
that at the same clock speed they have gained about 30% performance.
Not bad, but also not that impressive for 5 years work.

Intel's i series have not had any huge jumps in performance in quite
a few years, except for code taking advantage of new aes and sse 4.2
instructions, although my 3rd gen i7 in the laptop has aes too, so it
is just missing sse 4.2, and runs the same base clock speed as the one
in the NUC.  The laptop also has much faster graphics than the NUC's
intel graphics.

AMD is certainly looking very interesting these days (after years of
not being that interesting).
