27. Figure 1.1 Growth in processor performance over 40 years. This chart plots program performance relative to the VAX 11/780 as measured by the SPEC integer benchmarks
(see Section 1.8). Prior to the mid-1980s, about 22% per year, or every 3.5 years. 52% starting in 1986, or every 2 years, In 2003 the end of Dennard scaling 23% per year until
2011, or every 3.5 years. From 2011 to 2015, less than 12%, or every 8 years. Since 2015, the end of Moore’s Law, 3.5% per year, or every 20 years!
