 ARM binaries are quite a bit more compact than X86-64 binaries
which is why ARM hardware manages with less memory than PC hardware.

 But 512MB is a *lot* less than 8GB and won't have any cache space
available to speak of.

 You wouldn't 512MB is marginal for compiles really and probably
needs swap for some compiles - if you were using a 4GB Rock64 (or perhaps
even a 2GB Odroid C2) you'd expect to see similar speed up behaviour to your
8GB laptop.(
