Gordon Moore, the co-founder of Intel and Fairchild Semiconductor, described a doubling of transistors per integrated circuit in a 1965 paper. In 1975, he corrected the doubling rate to two years. Since then it has been used as an analogy in other fields.
The illustration below shows that, while transistor growth is still ongoing, clock frequency scaling has been replaced by scaling the number of cores. It even shows the reason behind this change: the power density limits clock speed.

What can we learn from this? While the insights from this are not exactly new, the illustration shows the directions of ongoing development (until 2015) for computer hardware, and emphasises the need for multi-processing.Enjoy. Please leave a comment below for questions and suggestions.
