Question: 1 / 690

Which processor size typically consumes the least amount of power?

28 nm

45 nm

32 nm

The size of a processor, expressed in nanometers (nm), refers to the manufacturing process or technology node used to fabricate the semiconductor chip. Smaller numbers indicate more advanced manufacturing technology, which typically allows for several benefits, including lower power consumption.

In this context, the 14 nm process represents a more advanced technology compared to 28 nm, 45 nm, and 32 nm. Processors made with a smaller node size, like 14 nm, are designed to use less power while still providing high performance levels. This is primarily because smaller transistors can operate with lower voltage levels and less leakage current, making them more efficient.

Although 32 nm does offer reduced power consumption compared to 45 nm and 28 nm, it does not achieve the same efficiency as 14 nm technology. Thus, the most power-efficient processor size among the options is indeed the one fabricated using the 14 nm process.
