Third-generation computers were offered well into the 1990s; for example the IBM ES9000 9X2 announced April 1994 [30] used 5,960 ECL chips to make a 10-way processor. [31] Other third-generation computers offered in the 1990s included the DEC VAX 9000 (1989), built from ECL gate arrays and custom chips, [32] and the Cray T90 (1995).
Aside from its clones, which started thirty years later, [38] it was the only calculating machine available anywhere in the world for forty years (Dorr E. Felt only sold one hundred comptometers and a few comptographs from 1887 to 1890 [39]). Its simplicity made it the most reliable calculator to date.

Computers built after 1972 are often called fourth-generation computers, based on LSI (Large Scale Integration) of circuits (such as microprocessors) – typically 500 or more components on a chip. Later developments include VLSI (Very Large Scale Integration) of integrated circuits 5 years later – typically 10,000 components.

The fact that the K computer is over 60 times faster than the Earth Simulator, and that the Earth Simulator ranks as the 68th system in the world seven years after holding the top spot, demonstrates both the rapid increase in top performance and the widespread growth of supercomputing technology worldwide.
