Which is the most powerful computer today?

Unless something has emerged in the last three months, the world's most powerful computer was announced in June this year. It is the US Department of Energy's Summit. This, at maximum, can operate at 200 petaflops. Since petaflop isn't in everyone's vocabulary yet I'll tell you that's 200 quadrillion calculations per second.

It makes you wonder why you ever struggled to learn your times tables, doesn't it? Summit by IBM has a competitor, Sunway TaihuLight. This was, I believe, the most powerful computer until Summit was completed. Sunway is from the National Supercomputing Center in Wuxi, China..

The most powerful computer in the world today is located in China. China is by far the leader in the world when it comes to making hardware for computers. The National Supercomputer Centre located in Wuxu, China houses the 93 petaflop Sunway TaihuLight, a computer that has the ability to be able to process information 93 trillion times per second thus making it the fastest computer in the world. An updated list of the fastest computers shows the 93 petaflop Sunway TaihuLight at the top, besting out the former fastest computer also from China called the Tianhe-2. As a matter of fact when it comes to the 500 fastest computers in the world, China is the leader with roughly 170 of them. The United States is just behind them with about 160 of the fastest computers worldwide. These computers are all used for all kinds of things such as weather predictions and data retrieval and storage.
