HYSYS isn't a video game, but its PFD (Process Flow Diagram) and 3D modeling environments (like the Flare System Analyzer) rely on decent graphics processing. Integrated Intel HD Graphics.
HYSYS benefits significantly from high single-core clock speeds (3.5 GHz+). While it does support multi-threading for certain solver tasks, a faster individual core is often more beneficial than having dozens of slower cores. 2. Random Access Memory (RAM) Aspen Hysys System Requirements
Dedicated GPU with at least 4GB VRAM (e.g., NVIDIA Quadro or NVIDIA GeForce RTX series). HYSYS isn't a video game, but its PFD
Never run Aspen HYSYS on a traditional mechanical Hard Disk Drive (HDD) if you can avoid it. While it does support multi-threading for certain solver
Intel Core i7/i9 or AMD Ryzen 7/9 (8 cores or more).
64 GB is advised if you are running HYSYS alongside other heavy hitters like Aspen Plus, AVEVA, or large Excel-based automation tools. 3. Graphics Card (GPU)
