Note that the sites here are much much smaller than the sites from the previous slides. While these machines are extremely energy efficient, the total power they consume are many magnitudes less than the most powerful machines. Most of the green machines are under 100 kW while the most powerful machines range from 2000 kW to near 18000 kW.

One thing pointed out in lecture I thought was kinda interesting is that all of these computers use the NVIDIA K20 GPU, mostly because it's impossible to get this low level of performance per watt with really large CPUs. The white paper here gives a bit of an overview of the technologies added to the K20 in addition to some performance comparisons with other hardware.
Watt does the W in MFLOPS/W mean?

Mega flops per watt
...Wait, watt do you mean by that question?
