There are also thermal efficiency opportunities by allowing more optimal component placement within a rack.

The higher the compression ratio, the higher the power output and the higher the thermal efficiency.
The thermal efficiency of the ICEs used in the Indy cars is over 45%.
The rocket engine power plant runs at a 35% thermal efficiency, versus 55% for conventional gas-fired plants.
Thermal efficiency is how much of the potential heat energy of the fuel used is actually returned as work at the wheels.
The key to thermal efficiency for internal combustion engines is compression ratio.
GM's researchers estimate its thermal efficiency at somewhere between 53% and 67%.
The higher the compression ratio, the higher the thermal efficiency.
For example, the first phase of the EU Emissions Trading program, which contained several design flaws that have since been rectified, has already been found to have reduced emissions by around 100 million tonnes of CO2 mostly by forcing a shift of load from coal to gas power plants and providing an incentive for inefficient coal plants to improve the thermal efficiency of their boilers.
Factor in the Kepler architecture's great efficiency and low thermal design power and the GTX 660 Ti assures gamers of having the most stable, quiet and power-efficient gaming experience possible in its price class.
