Madhu,

SMP requires a single computer with multiple cores.  If and when you
buy a computer with multiple cores, I encourage you to buy one where
all the cores are the same.

BTW: in both Arm and Intel, the lowest end multi-core CPU PCs use a
single socket solution, so you have absolutely no option of having
different architectures on that single socket.
