Processor
Ansys users should prioritise core count over CPU frequency (GHz). The boost in performance is almost linear for each additional core, and for this reason, the optimal solution for Ansys is a HEDT and dual CPU workstation.
Memory
Ansys can be quite RAM hungry, and the general rule of thumb is 8GB RAM per CPU core.
Note that HEDT and dual CPU platforms have much greater RAM capacity and bandwidth than standard consumer grade CPU's.
Graphics Card
Graphics cards can affect performance in Ansys, but a powerful GPU isn’t always the ideal solution.
Depending on your budget, you may get much greater performance from a faster CPU without a GPU at all than if you were to allocate that budget towards a GPU.
It’s important to consider other software that you may work with that could require GPU power.
Storage
In the past, computers were held back by slow mechanical hard drives. Unless you are storing files which are not accessed too often, in which case mechanical hard drives might be a better choice, Solid State drives should be used for everything else. Having everything stored on SSDs means you’ll be able to copy, move, open and save files quickly and PC and program start times will be reduced.
