IBM's Sequoia - No. 1 supercomputer
Authored by: Chromatix on Monday, June 18 2012 @ 09:44 PM EDT
In fact, the power wall has been a factor quite often limiting the performance of high-end machines. Intel hit it hard with the Pentium 4 (especially Prescott) and had to change their entire design strategy forthwith, and graphics card manufacturers also now design to power consumption targets (set by the slot and auxiliary power input specifications) instead of raw hardware limits.

The fact is, the actual processing hardware will consume only about half the total power in a typical datacentre. The rest is spent on the cooling systems required to remove the resulting heat. Hardware tends to be packed about as tightly as possible under heat dissipation considerations - and servers tend to be painfully loud due to the high airflow requirements. High performance- per-watt is now a very important metric for all types of servers.
