Transistor Size Changes

During 1971 the first commercial microprocessor was 1,000 times bigger than today’s when it was released.

During 2007, the state-of-the-art for Intel was 3.3 million transistors per square millimeter. Now in 2018, 100 Million Transistors are in each square millimeter.

Intel has just announced the first microchip that contains more than two billion transistors - tiny switches that together perform the calculations in computers.

As of 2017, the largest transistor count in a commercially available single-chip processor is 19.2 billion— AMD's Ryzen-based Epyc. In other types of ICs, such as field-programmable gate arrays (FPGAs), Intel's (previously Altera) Stratix 10 has the largest transistor count, containing over 30 billion transistors

Intel has just announced the first microchip that contains more than two billion transistors. The chip, known as Tukwila, marks a milestone in chip density technology.
Meanwhile software bloat diminishes the amazing hardware changes and common laptop computers still lag as they did a number of years ago. Just as with TVs, hardware is progressing faster than our ability to take advantage of it.

Intel's latest chips, based on Kaby Lake, are made using a 14-nanometer process, and the company is now moving to 10-nm with its upcoming Cannonlake chip, which was shown in a PC at CES 2017.
14 nm – 2014 still using in 2018
10 nm – 2017 (now 2019)
 7 nm – 2018 (7nm pilot plant set in 2017 to determine how to make in volume)
 5 nm – 2020

Incidentally, to offer perspective, nano means one-billionth, so one nanometer (nm) is one-billionth of a meter (3.2 feet). There are 25,400,000 nanometers in one inch. A strand of human DNA is 2.5 nanometers in diameter. A human hair is approximately 80,000 - 100,000 nanometers wide.
