Each [[process node]] can be analyzed and characterized based on the three major components known as power, performance, and area. The three components dictate the capabilities of the integrated circuits fabricated on it. For example, [[TSMC]] [[16 nm process]] is said to have 38% performance improvement at iso-power, 54% lower power at iso-speed, while achieving up 2x gate density improvement compared to its own [[28 nm process]]. It's worth pointing out that the [[figure of merit]] for the publically disclosed performance and power numbers are often based on fairly simple circuits such as a [[ring oscillator]]. It's also important to note that those numbers represent the extremes ends of the VI curves. Most circuits will find a more balanced optimization point between the two, allowing for a modest circuit shrink while enabling both performance and power reduction. | Each [[process node]] can be analyzed and characterized based on the three major components known as power, performance, and area.
