On Google Cloud hyperdisks can be used on h3, c3, c3d, m3, n4 instance types and are required for n4. I.e., you are not allowed to use the n4 instance type without using a hyperdisk.
Its the only instance class that's on Emerald Rapids. So if you want the best that Intel has to offer, you need to adopt hyperdisks.
But, to be clear: We're not.
Curious what the use case is for targeting a specific CPU. These are virtual CPUs anyways, so what benefit does using the latest intel chip offer?
Sometimes the instruction sets change (like the relatively recently added AVX10 extensions) and you have a workload that specifically needs those? I'm just guessing though.
