Torch was tested in June 2025 using the LINPACK benchmark system, which is the basis for all HPC systems ranked on the Top500 list. It had a theoretical maximum performance of 12.25 PF/s thanks to its powerful GPU resources, of which LINPACK was able to use 10.79 PF/s, thus placing it at #133 on the listed.

Torch was recently ranked #40 on the Green 500 list, a global list of the most energy efficient supercomputers in the world thanks to its advanced liquid cooling system.
