Green500
A Green500 is a ranked system list of HPC systems that focuses on performance per watt.
- Context:
- It can (typically) be generated Semiannually.
- It can (typically) report Green500 Statistics, such as ...
- It can (typically) publish a Green500-based Projection Chart, ...

- The Green500 is a biannual ranking of supercomputers, from the TOP500 list of supercomputers, in terms of energy efficiency. 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).

- QUOTE: The purpose of the Green500 is to provide a ranking of the most energy-efficient supercomputers in the world. For decades, the notion of "performance" has been synonymous with "speed" (as measured in FLOPS, short for floating-point operations per second). This particular focus has led to the emergence of supercomputers that consume egregious amounts of electrical power and produce so much heat that extravagant cooling facilities must be constructed to ensure proper operation. In addition, the emphasis on speed as the ultimate metric has caused other metrics such as reliability, availability, and usability to be largely ignored. As a result, there has been an extraordinary increase in the total cost of ownership (TCO) of a supercomputer.
