FEM (Finite Element Method) works better with PRO NVIDIA cards because they do have double float math multiplier unlocked. Crypto "mining" is using INT calculations only so gamer cards work as good as pro ones.
There where a way to re-solder resistor or two to unlock multiplier on gamer NVIDIA cards (use search engine for something like "how to enable full speed FP64 in NVIDIA GPU").
More double float calculation power your supercomputer delivers more FEM nodes can be in your model - more accurate result could be.
