Data Center
El Capitan (LLNL)
The fastest disclosed computer on Earth: MI300A APUs for the nuclear stockpile.
El Capitan at Lawrence Livermore topped the TOP500 in November 2024 at 1.742 exaFLOPS, built by HPE from 44,544 AMD MI300A APUs. Its mission is classified stockpile stewardship: a reminder that state compute still rivals the biggest commercial clusters.

Chip
AMD Instinct MI300A
CPU and GPU on one package with unified HBM: the chip inside El Capitan.
The MI300A fuses 24 Zen 4 CPU cores and CDNA3 GPU compute onto one 3D-stacked package sharing 128 GB of HBM3: no PCIe hop, no separate memory pools. It powers El Capitan at Lawrence Livermore, the world's fastest disclosed supercomputer on the November 2024 TOP500 list.
