This is more and more tangent, but anyway: I think you should look around 
more carefully.  The Raspberry Pi 4B has a quad-core ARM CPU (Cortex A72) 
whose single core benchmark on that website is 456.  And nowadays "thin 
client" computers, in which slow CPUs are used, are very common both in 
industry and in schools/universities.  One random example, which I've seen 
a few days ago, is the Dell Wyse 3040, which is equipped with an Intel 
Atom X5 Z8350 CPU, whose single core benchmark is 480.
