The Green500 is a biannual ranking of supercomputers, from the TOP500 list of supercomputers, in terms of energy efficiency.[1][2] The list measures performance per watt using the TOP500 measure of high performance LINPACK benchmarks at double-precision floating-point format.
In 2022, Hewlett Packard Enterprise took the lead (then later in Nov. 2022 Lenovo took the lead, though with a much smaller Nvidia based system), with AMD-based systems (AMD CPUs and AMD GPUs) in the 4 top positions, with the top position over 50% more efficient than the previous year (Japanese) top position. And number two on the list (the current fastest on TOP500) is also over 50% more efficient than the currently most efficient (and much smaller) Nvidia-based system. No large Nvidia-based system make the top 10 positions of Graph500 (smaller ones in 7th to 10th, nor any longer any (small or large) ARM-based (Fugaku was at the top of the list in June 2021).
