How this table is built

Full methodology

Benchmark figures come from the TOP500 list and link their TOP500 record. What each system runs, how to apply for time, cooling, power and upgrade plans come from the operator’s own pages. The small marker next to a figure opens its source. Empty cells mean nobody publishes the figure; we never estimate.

Each row carries the date we last checked it, and the newest check was 11 Nov 2026. Spot a stale number? Email hello@hpclist.com with the source and we update the row.

Questions buyers ask

What is the fastest supercomputer in the world?

LineShine at the National Supercomputing Centre in Shenzhen, with 2,198.4 PFLOP/s Rmax on the June 2026 TOP500, from 13,789,440 cores at 42,220 kW. El Capitan at LLNL follows with 1,809.0 PFLOP/s, then Frontier (1,353.0) at Oak Ridge, Aurora (1,012.0) at Argonne and JUPITER Booster (1,000.0) at Jülich.

What do Rmax and Rpeak mean?

Rmax is the double-precision performance a system measured on the HPL (LINPACK) benchmark. Rpeak is the theoretical peak of its hardware. Rmax divided by Rpeak is HPL efficiency: El Capitan runs at 64.1%, Frontier at 65.8% and Aurora at 51.1%. Neither figure measures AI or mixed-precision throughput, which is much higher on GPU systems.

How many supercomputers have passed one exaflop?

Five in this dataset have passed 1,000 PFLOP/s on HPL: LineShine, El Capitan, Frontier, Aurora and JUPITER Booster. JUPITER sits exactly at 1,000.0 PFLOP/s. Rmax and Rpeak, power and efficiency for each are on the exascale hub.

Which interconnect do the biggest systems use?

InfiniBand is on 64 of the 105 systems and HPE Slingshot on 26. Slingshot-11 connects El Capitan, Frontier, Aurora, HPC7, Alps and LUMI, while JUPITER Booster, Eagle and Leonardo use InfiniBand. Fugaku uses Tofu interconnect D and Sunway TaihuLight its own network.

Which supercomputers are the most energy efficient?

Among systems that report power, Portage delivers 66.22 GFLOP/s per watt on LINPACK, ahead of HPC7 (65.43), Hunter (64.65), JUPITER Booster (63.32) and rzAdams (62.84). Efficiency here is Rmax divided by the power the site reported for its benchmark run.

Is this the TOP500 list?

No. TOP500 ranks the 500 fastest systems twice a year, and its benchmark figures here are credited to TOP500.org. HPC List adds what the list leaves out, from the operators’ own pages: what each system is used for, how researchers apply for time, cooling and power design, the facility and announced upgrades or successors. It also computes efficiency and GFLOP/s per watt and links every value to the page it came from.
