 While they were technically powerful computers, the Power Mac series suffered from the perception that they were slower than their Intel-based counterparts because their PowerPC CPUs listed slower clock speeds.Rubinstein and Apple popularised a term known as the Megahertz myth, to describe how the PowerPC architecture could not be compared to the Intel architecture simply on their clock speeds (the PowerPC CPUs, despite their lower clock speeds, were generally comparable to Intel CPUs of the era).Due to the relatively low sales of its Mac computer brand, Apple decided to expand its ecosystem in order to increase its consumer awareness.
