RSX（Reality Synthesizer）（现实合成器）是一个由Nvidia和索尼合作开发的PlayStation3游戏机专有图形处理单元（GPU）。
除非另有说明，以下规格是均出自索尼在2005年E3大会上发表的新闻稿[1]，或是同一届会议上的幻灯片[2]，或是索尼在2006年游戏开发者大会上的幻灯片介绍[3]。

新闻发布
[编辑]Sony staff were quoted in PlayStation Magazine saying that the "RSX shares a lot of inner workings with NVIDIA 7800 which is based on G70 architecture."[12]由于G70能够执行每时钟周期136着色器的操作，在RSX预计将配备数量相同的G70并行的像素和顶点着色渲染管线的，其中包含24个像素和8条顶点管线[13]。
Nvidia CEO Jen-Hsun Huang stated during Sony's pre-show press conference at E3 (Electronic Entertainment Expo) 2005 that the RSX is twice as powerful as the GeForce 6800 Ultra.[2]
