Ranked: Gas Prices Around the World in 2025

Key Takeaways Fuel prices in Hong Kong rank as the highest globally, at $3.07 per liter in 2025. Several European cities rank among the world’s most expensive for gasoline, driven by energy supply shocks. Riyadh, Saudi Arabia has seen the fastest price increase since 2020 across 69 cities analyzed, with fuel costs up nearly 49%.…

Oil Prices Edge Higher After Steep Two-Day Selloff

Oil prices recovered slightly in early Asian trading on Wednesday after two straight sessions of steep declines, as traders weighed the prospect of a larger OPEC+ output increase against signs of tighter U.S. crude inventories. At the time of writing, Brent futures for December delivery had climbed to $66.17 while WTI was trading at $62.50, up 0.21% on the…

Details as Nigerian Immigration Begins Clampdown on Foreigners with Expired Visas

By Abiola Olawale The Nigeria Immigration Service (NIS) has announced its decision to kick off a sweeping nationwide crackdown on foreign nationals overstaying their visas or breaching entry conditions. The NIS said the enforcement action began immediately following the expiration of a generous amnesty program on September 30, 2025. The New Diplomat reports that the…

In this graphic, we visualize the performance and power consumption of the world’s top 10 supercomputers.

Data and Key Takeaways

The data we used to create this graphic is listed in the table below. Figures come from TOP500’s November 2024 ranking.

Country System Manufacturer Hardware supplier Max Performance

🇺🇸 US Tuolumne HP Enterprise AMD 208 3,387

This ranking highlights America’s position as a global leader in computing power. For instance, the top three supercomputers are located in the U.S., and all of them are classified as exascale systems.

This is a significant change from the 2021 ranking, in which Japan’s Supercomputer Fugaku held the top spot.

The winner of this year’s ranking is El Capitan, which became operational in 2024 and is the third exascale system deployed by the United States.

Sponsored by the U.S. Department of Energy, El Capitan was manufactured by HP Enterprise Cray and features an unknown number of AMD Instict MI300A accelerated processing units (APUs).

What’s An Exascale Computer?

An exascale computer is capable of performing at least 1 exaflop (1 quintillion operations per second).

Note that in this ranking, performance is measured in petaflops (1 quadrillion). 1,000 petaflops is equal to 1 exaflop.

In realistic terms, exascale computers can handle massive datasets and solve problems at unprecedented speed. Use cases include:

  • Simulating molecular interactions
  • Predicting climate change
  • Advancing nuclear research
China’s Exascale Systems Remain a Mystery

Since 2021, reports have suggested that China does indeed have its own exascale systems, but is simply withholding information about them from global rankings such as the TOP500.

It’s a well known situation that China has these computers, and they have been operating for a while. They have not run the benchmarks, but [the community has] a general idea of their architectures and capabilities.
JACK DONGARRA, CO-FOUNDER OF TOP500

China’s silence is likely related to its geopolitical strategy. Publicly announcing it has built its own exascale systems could result in further U.S. trade restrictions.
