- The datacenter CPUs are not as bad as you'd think, as they operate at a fairly low clock compared to the obscenely clocked desktop/laptop CPUs. Tons of their power is burnt on IO and stuff other than the cores.

- Hence operating more Apple-like "lower power" nodes instead of fewer higher clocked nodes comes with more overhead from each node, negating much of the power saving.

- But also, beyond that point... they do not care. They are maximizing TCO and node density, not power efficiency, in spite of what they may publicly say. This goes double for the datacenter GPUs, which operate in hilariously inefficient 600W power bands.
