Since some years, there are rumors available that the Moores law isn't visible anymore. Sometimes it was argued, that the improvement rate in chip performance has slowed down. To investigate the situation with valid numbers lets us take a deeper look into the performance of different Thinkpad models. The main reason why this computer was selected is because its manufactored under the same name over many years which makes it easy to campare the performance.
The table shows different 14 Inch Thinkpad models from 2011 until 2024, including a common Intel i7 cpu from this year together with the proposed Gflops performance. its visible that the speed has improved, a thinkpad from 2023 is 6 times faster, than the counterpart from the year 2011. But, the improvement per year, is smaller than the expected improvement:
In reality, the gflops has improved by 19% each year, while the moores law expects an improvement of 59% for each year. What we see in the reality is no longer an exponential curve, but a slow increase over a longer horizon. It doesn't take 18 months until the performance has doubled but in reality it takes 7 years.
