Capacity Planning vs. Hardware Sizing

I have been recently working on business proposals which require me to architect solutions starting from layers to deployment. This is where I crashed into these 2 terms: Capacity Planning & Hardware Sizing. I came across an accurate difference here which I would like to quote straight away:
“decide whether you need to do capacity planning or hardware sizing, you can’t do both, at least not at the same time. In capacity planning the software and hardware are constant while the workload varies (ie, given a particular system, how much work can it do?). In hardware sizing the software and workload are constant while the hardware varies (ie, given a particular amount of work, what’s the least-costly system that can handle the workoad in the specified performance constraints?).”
I am going to edit this space as my thoughts mature.
