The 9 Most Powerful Supercomputers in The World [Infographic]

The most powerful Supercomputers function on the same basic principles as everyday computers, but their power and speed are far greater. They resemble old mainframes in appearance. Unlike regular desktop PCs or laptops, supercomputers handle massive datasets and execute calculations at extraordinary speeds, positioning them as the fastest computers on the planet, according to IBM. These systems demand an immense amount of infrastructure, including sophisticated cooling mechanisms, to keep running efficiently.

In terms of architecture, supercomputers far surpass typical PCs. While your laptop may feature one central processing unit (CPU) and one graphics processing unit (GPU), a supercomputer may contain thousands of each, with each unit far more powerful than those in consumer devices.

The performance of supercomputers is measured in floating-point operations per second (FLOPS), which quantify mathematical computations.

The most powerful supercomputers today surpass 1 exaFLOP, equivalent to 1 quintillion FLOPS (10^18). For context, a typical laptop or PC may reach several hundred gigaFLOPS (1 trillion FLOPS, 10^9). These exascale supercomputers are a step beyond current systems, pushing the boundaries of what’s possible in scientific and industrial research.

Given their immense computational power, supercomputers are often employed to tackle challenging problems in fields such as drug and material discovery.
