Nvidia's accelerators, like the Grace Hopper Superchip, dominate the Green500 rankings for sustainability, powering eight of the ten most energy-efficient supercomputers.
The latest Green 500 list highlights Nvidia's GH200, which powers the two most efficient systems, achieving over 70 gigaFLOPS per watt in performance.
Despite Nvidia's current dominance in sustainable supercomputer rankings, new chips like the GB200 could challenge their efficiency due to higher power consumption.
While the GH200 shows significant performance, the transition from A100 to H100 indicates mixed results in performance per watt when comparing to power levels.
