I don't think you can answer that just by considering the average
number of cores in a CPU. Even if my CPU has 4 cores, most of the
time the Python code I run on it isn't going to take advantage of
more than one of them, simply because it's not written to be
multi-threaded.

I would not like to be in a position where I *have* to use some
number of cores in order to get reasonable performance from my
Python code.
