Gephi is a cross-platform application, as it is developed in Java. It was successfully tested on many different architecture, OS and graphical configuration. Gephi requires Java version 7 and later, get it here.
Minimum hardware requirements
500 MHz CPU + 128 MB RAM + OpenGL 1.2
There is no absolute minimum. This is a practical minimum. Performance is a function of graph size.
(nodes + edges)
Note that Gephi has been successfully tested on Netbooks, running on Intel® Atom.
Gephi uses an OpenGL 3D engine to speed up graph visualization. However a compatible graphic card is required. If your graphic card is older than 8 years, or if your laptop doesn’t have a dedicated graphic card, you may have to upgrade your hardware to run Gephi.
If you’re running on Linux, get latest vendor graphical drivers to ensure OpenGL hardware acceleration.
