Intel has moved from planar transistors to, 3D, tri-gate transistors. This allows for the increase of speed, reduced power consumption (50% at constant, 37% in low voltage conditions), and of course performance and efficiency. Intel found that shrinking to 22nm did not meet Moore's Law expectations, but changing the individual transistor functions was the only way to meet the goal. Estimates bring the manufacturing costs of the tri-gate to 2-3% over current silicon-wafer construction. The 3D transistor processor, codenamed Ivy Bridge, will go into production and distribution in the second half of 2011. 14nm and 10nm chips with 3D transistors are being planned for 2015. Intel states that this tech is not limited to the cutting edge, so we will see wide adoption of the technique across Intel's product families.
I included the above video for Mark T. Bohr's deadpan performance. He made the corny jokes in the video, acceptable. Like the tri-gate transistor, that is a commendable achievement in itself.
