外觀
RSX(Reality Synthesizer)(現實合成器)是一個由Nvidia和索尼合作開發的PlayStation3遊戲機專有圖形處理單元(GPU)。
除非另有說明,以下規格是均出自索尼在2005年E3大會上發表的新聞稿[1],或是同一屆會議上的幻燈片[2],或是索尼在2006年遊戲開發者大會上的幻燈片介紹[3]。

新聞發布
[編輯]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]由於G70能夠執行每時鐘周期136着色器的操作,在RSX預計將配備數量相同的G70並行的像素和頂點着色渲染管線的,其中包含24個像素和8條頂點管線[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]
