Question "Instant wake/resume": to what extent is the hardware determining this speed versus the operating software?

[GalacticJuggernaut]

I do have some anecdotal "proof" it must be mostly and primarily hardware driven but I am curious if anyone knows more on this subject. What makes this work exactly from a technical perspective?
While its maybe a seemingly minor thing to most, for my impatient self this feature has come to be a main and super important part of my user experience. You do not realize how important it is until its gone (which happened to me recently on a brand new laptop purchase)

IN the market and I am looking for the fastest wake laptop on the market but with the exception of 1 brand I have found (Razer), no one really talks about this feature

So then don't let it turn off.
Maybe let the monitor sleep.

Other than that, a touch of the mouse or trackpad...1 second or less and it is ON.
