Workstation options

Hi everyone,

I’m planning to buy a workstation mainly for GROMACS simulations, but I’m confused between two options within my budget:

Option A: RTX 5080 + 64 GB RAM

Option B: RTX 5090 + 32 GB RAM

From a GROMACS performance point of view, which setup would be the better choice overall?

Also, how important is system RAM vs GPU power for typical GROMACS runs?

Thank you!

Hi!

The size of RAM is largely irrelevant; GROMACS mdrun uses very little. Same for GPU memory.
