Gitbrew to Release RSX Tools in Exchange for $300 in Donations

Gitbrew has offered to release their RSX ‘Reality Synthesizer' if they can accumlate $300 dollars.

The RSX ‘Reality Synthesizer’ is a proprietary graphics processing unit (GPU) codeveloped by Nvidia and Sony for the PlayStation 3 game console.

Unless otherwise noted, the following specifications are based on a press release by Sony at the E3 2005 conference, slides from the same conference, and slides from a Sony presentation at the 2006 Game Developer’s Conference.
