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]
