#' Characteristics of computer central processing unit chips over the decades
#'
#' Since single-chip central processing units were introduced in the early 1970s,
#' performance has increased exponentially. Around 1965, Gorden E. Moore, a co-founder
#' of the integrated circuit giant Intel, postulated that capacity of chips, measured as
#' the number of transistors, doubles approximately every two years. Known as Moore's Law, this
#' pattern has held true for decades.
