About This Dataset
World's Most Powerful Supercomputers 2025
This chart shows the ten highest-ranked systems in TOP500’s June 2025 edition, ordered by measured High Performance Linpack (HPL) performance. It is a dated snapshot, not a live ranking for the whole of 2025.
The unit is petaFLOPS: one petaFLOPS is one quadrillion floating-point operations per second. The source’s exaFLOPS values for the leading systems are expressed here in petaFLOPS; 1 exaFLOPS equals 1,000 petaFLOPS.
HPL measures performance on a specific numerical benchmark. It differs from theoretical peak performance, energy efficiency and performance on other workloads.
Figures follow the precision in TOP500’s June 2025 announcement. JUPITER Booster’s result was preliminary and measured on a partial system during commissioning. Later editions can change both scores and positions.

Analysis
El Capitan leads with 1,742 petaFLOPS, ahead of Frontier’s 1,353 and Aurora’s 1,012. The leading pair are separated by 389 petaFLOPS. These are the three systems in this snapshot above 1,000 petaFLOPS. JUPITER Booster is fourth at 793.4, followed by Eagle at 561. The tenth system, Leonardo, records 241.2, giving the displayed top ten a range of 1,500.8 petaFLOPS. Comparisons here apply to HPL results, not to every scientific or AI task.
