Although there was a trend of steady progress in the Green500, nothing has indicated a big step toward newer technologies.

The system to snag the No. 1 spot for the Green500 was MN-3 from Preferred Networks in Japan. Knocked from the top of the last list by NVIDIA DGX SuperPOD in the US, MN-3 is back to reclaim its crown. This system relies on the MN-Core chip, an accelerator optimized for matrix arithmetic, as well as a Xeon Platinum 8260M processor. MN-3 achieved a 29.70 gigaflops/watt power-efficiency and has a TOP500 ranking of 337.

HiPerGator AI of the University of Florida in the USA is now No.2 on the Green500 with a 29.52 gigaflops/watt power-efficiency. An NVIDIA machine boasts 138,880 cores, much more than any other machine in the Top5 of the Green500. Like many other systems on the list, this supercomputer utilizes an AMD processor – specifically the AMD EPYC 7742. With an overall performance that outpaces most of the other competition on the Green500, it's no surprise this machine holds the 22nd spot on the TOP500 list.

The Wilkes-3 system out of the University of Cambridge in the U.K. has achieved the No. 3 spot. A Dell EMC machine, this supercomputer had an efficiency of 28.14 gigaflops/watt. Like HiPerGator AI, this system relies on an AMD EPYC processor – the AMD EPYC 7763. This system is ranked 101 on the TOP500 list.

The MeluXina machine of LuxProvide holds the No. 4 spot on the Green500. It's also unique in that it is the only machine on the list from Luxembourg. Like many other machines, MeluXina is also using an EMD EPYC processor. This system's efficiency was clocked at 26.96 gigaflops/wat, and it is ranked 37 on the TOP500.

Rounding out the Top5 of the Green500 is NVIDIA DGX SuperPOD. Created by NVIDIA in the USA, this machine also relies on an EMD EPYC processor. Ranked 216 on the TOP500, this system achieved 26.20 gigaflops/watt of efficiency. Again, this machine has an AMD EPYC processor.

Outside of the Top5, an incredible development is the Perlmutter system. This supercomputer was the only new machine in the Top10 in the TOP500 rankings; it also claims the No. 6 spot on the Green500. With a performance of 64.6 Pflop/s, this supercomputer's power efficiency of 25.55 gigaflops/watt is quite impressive.
