That is definitely the objective but the reality is that load is not* uniform over the day. So you are paying to keep some number of servers hot (I don't know about spinup/spindown practices in modern datacenters).

I doubt this applies to HPC (the target market for this part) as they either schedule jobs closely or could, I imagine, shut them down. But I'm not in that space either so this is merely conjecture.

* I am sure there are corner cases where the load is uniform, but they are by definition few.
