These methods became especially popular in the mid to late 2000s during the [[seventh generation of video game consoles]] that included the [[IBM]] [[PowerPC]] based [[PlayStation 3]] (PS3) and [[Xbox 360]] consoles. Historically, [[game console]]s often have relatively weak [[central processing unit]]s (CPUs) compared to the top-of-line desktop computer counterparts. This is a design choice to devote more power and [[transistor budget]] to the [[graphics processing unit]]s (GPUs). For example, the 7th generation CPUs were not manufactured with modern [[out-of-order execution]] processors, but instead use [[in-order processor]]s with high clock speeds and deep [[Pipeline (computing)|pipelines]]. In addition, most types of computing systems have [[main memory]] located hundreds of [[clock cycle]]s away from the [[processing element]]s. Furthermore, as CPUs have become faster alongside a large increase in main memory capacity, there is massive data consumption that increases the likelihood of [[cache misses]] in the [[system bus|shared bus]], otherwise known as [[Von Neumann architecture#Von Neumann bottleneck|Von Neumann bottlenecking]]. Consequently, [[locality of reference]] methods have been used to control performance, requiring improvement of [[memory access pattern]]s to fix bottlenecking. Some of the software issues were also similar to those encountered on the [[Itanium]], requiring [[loop unrolling]] for upfront scheduling.
