TOP500 supercomputers
The world's five hundred fastest ranked machines, measured the way science measures: FP64, sustained, on a real solver. Fifteen exaflops sounds enormous and is a thousandth of the headline — because the headline is half precision, and because these machines are built from the very GPUs already counted.
TOP500 supercomputers over time
Installed compute in zettaFLOP/s, log scale, 2008 → present. A straight line on this axis means steady exponential growth; the slope is the doubling rate. History before the 2026 anchor is reconstructed — see the methodology.
Aggregate Rmax of the TOP500 list, FP64 LINPACK — context only.
~15 EFLOP/s aggregate Rmax at double precision. LineShine leads at 2.198 EFLOP/s; El Capitan and Frontier follow.
Why it is excluded: Overwhelmingly assembled from NVIDIA and AMD datacenter GPUs already in the AI-accelerator lines. Summing it would count the same racks twice.
