The 9 most powerful supercomputers in the world today.

Supercomputers operate on the same principles as regular computers, but with superior performance and a much larger size, reminiscent of the classic computers of the past.

Unlike desktop or laptop computers, they process massive amounts of data and perform calculations at incredible speeds. According to IBM, supercomputers are the fastest machines in the world, requiring complex infrastructure to operate, including advanced cooling systems.

Architecturally, supercomputers are equipped with far more powerful components than conventional PCs. While a laptop might only have a central processing unit (CPU) and a graphics processing unit (GPU), a supercomputer can possess thousands of CPUs and GPUs, each with performance far exceeding that of typical commercially available components.

Their performance is measured in floating-point operations per second (FLOPS). While PCs or laptops only reach a few hundred gigaFLOPS (equivalent to trillions of FLOPS), the world's most powerful supercomputers today have surpassed 1 exaFLOP, equivalent to one quadrillion (10¹⁸) FLOPS. Machines that reach this level are called exascale supercomputers.

Thanks to their ability to process enormous amounts of data at incredibly high speeds, supercomputers have become indispensable tools in many scientific fields. They support research and development of drugs, discovery of new materials, weather forecasting, and can even "learn" to play chess, like Deep Blue, IBM's legendary supercomputer that defeated Russian chess player Garry Kasparov in 1997.
