I wonder where this requirement comes from ...

OP works for Red Hat, and some of the tests require booting systems with 64k pages.

What surprises me more is why Red Hat doesn't provide them with the proper hardware..

OK, but then why an 80-core CPU?

@lisper because Q32 is more expensive than Q64 and I got offer for Q80 one.

Amount of options for sensible AArch64 hardware is too small (or too expensive).

OK, this is something I know very little about so you may have to explain it like I'm a complete noob, but I still don't understand why, if all you want to do is boot 64-bit Linux, you couldn't use, say, a Raspberry Pi 4 instead of spending thousands of zloties on an 80-core machine that requires industrial cooling.
