Supercomputer vs. Mainframe Computer

Supercomputers and Mainframe computers are systems that are widely using in all over the world in different fields. Both have some features such as operations, performance, size, and some other features.

Main Difference

Supercomputer helps to resolve the complications of mathematics.  It works with most high speedily. On the other hand, Mainframe Computer is a system that can store large amounts of data.

Moreover, a Supercomputer is the fastest as compared to Mainframe Computer. Let us discuss the main difference between Supercomputers and Mainframe computers in detail.

What is Supercomputer?

The Supercomputer is the fastest system that performs complex mathematical problems. The inventor of this system is Seymour Cray invented it in 1976. Moreover, Supercomputer is very large compared to other systems.

It is a super-fast system that executes billions of operations in a second. Furthermore, it is a highly costly system and more expensive than all other computers. The capability to do work on Supercomputer is much better. In addition, Supercomputer is the most advanced and highest-quality system widely used worldwide. It is serving in different fields and making our work easier.


  • Great size
  • More expensive than others
  • Widely using
  • Fastest system
  • Huge range
  • Execute billions of processes
  • Performance is best
  • Advance technology
  • Larger memory capacity
  • High-speed system

What is Mainframe Computer?

A mainframe computer is an advanced system in which users can store a large amount of data. It is an expensive but affordable system compared to most other computers. Users can take it in a standard size that people can adjust everywhere. IBM invented the Mainframe computer, a highly famous computer company. Moreover, it is the fastest system that feeds extensive data in a short time.

Furthermore, it can run more than one operating system accompanying. In addition, Mainframe Computer is more efficient than Supercomputer. It has been beneficial since its invention.


  • Affordable price
  • Breakneck speed
  • Highly storage
  • Widely use
  • Efficient
  • Operate simultaneously
  • Standard size
  • Powerful computer system

Key Differences between Supercomputer and Mainframe Computer

  1. The Supercomputer is the most expensive as compared to Mainframe Computer.
  2. Supercomputer works more fastly as opposed to Mainframe Computer.
  3. A supercomputer is more efficient. On the other hand, Mainframe Computer is less efficient.
  4. The Supercomputer is available in a large size while Mainframe Computer is in standard size.
  5. The Supercomputer performs operations in seconds, while the Mainframe computer executes the instruction simultaneously.
