Hello GROMACS Users,
Does anyone know the “extent” to which the type and memory of RTX 40 series GPUs affect simulation performance? Currently, the price differences are substantial; for instance, the 4060Ti-8GB costs $450, the 4070Ti-12GB costs $800, while the 4090-24GB is priced at $1,900. I would like to know if the performance improvement justifies the price difference.
Moreover, I’m interested in determining which configuration offers optimal performance:
- Using four 4060Ti-8GB GPUs (totaling 4 x $450)
- Using two 4070Ti-12GB GPUs (totaling 2 x $800)
- Using one 4090-24GB GPU priced at $1,900
My simulations involve approximately 1 million atoms.
Thank you all in advance for your insights!
