Changes

As manufacturing processes evolved in accordance with Moore’s Law which saw the size of a transistor shrink, it allowed for the number of transistors packed onto a single processor die (the physical silicon chip itself) to double roughly every two years. This enabled the available space on a processor die to grow, allowing more cores to fit on it than before. This led to an increased demand in thread-level parallelism (TLP) which many applications benefitted from and were better suited for. The addition of multiple cores on a processor also increased the system's overall parallel computing capabilities.
