Environmentally Responsible Supercomputing
The Green500 provides rankings of the most energy-efficient supercomputers in the world. We raise awareness about power consumption, promote alternative total cost of ownership performance metrics, and ensure that supercomputers only simulate climate change and not create it.
The Green500 List
As in the previous edition of the list, an IBM Blue Gene/Q supercomputer tops this edition of the Green500 at 2026 MFLOPS/W. The top five positions are occupied by IBM Blue Gene/Q solutions at various locations. Seven of the top 10 greenest supercomputers in the world changed in this latest edition of the Green500 List. However, despite this significant upheaval, the ten greenest supercomputers in the world continue to follow one of two trends: (1) aggregating many low-power processors like IBM BlueGene/Q and (2) using energy-efficient accelerators, typically from the gaming/graphics market, e.g., AMD Radeon GPU, NVIDIA Tesla Fermi GPU, Cell, and Intel Knights Corner, to complement the commodity CPUs from Intel and AMD.
