Another type of competitive edge used by console manufacturers around the same time was the notion of "bits" or the size of the word used by the main CPU. The TurboGrafx-16 was the first console to push on its bit-size, advertising itself as a "16-bit" console, though this only referred to part of its architecture while its CPU was still an 8-bit unit. Despite this, manufacturers found consumers became fixated on the notion of bits as a console selling point, and over the fourth, fifth and sixth generation, these "bit wars" played heavily into console advertising. The use of bits waned as CPU architectures no longer needed to increase their word size and instead had other means to improve performance such as through multicore CPUs.
