How to choose: answering the main questions
High core count or high frequency?
Look at the license and the solver: ANSYS is licensed by core, so the performance of each core is critical; Python/statistics scale horizontally. Sometimes 16 fast cores are more cost-effective than 64 slow ones, both in terms of hardware price and licensing.
How much memory is needed for CFD/FEA?
Rule: 8–16 GB per million cells/elements. Tasks involving 20–50 million cells require 256–512 GB — choose platforms with a high number of DDR4/DDR5 slots.
GPU-accelerated computing?
Modern solvers (Fluent GPU, Abaqus, ML approaches) on A100/H100 cards provide a 5–20x boost. This is our GPU section—we calculate CPU+GPU hybrid configurations for your specific software package.
