The Inq follows up their ATi memory addressing discovery with one on the green side of the camp. Seems all this video RAM is aimed squarely at the rendering peeps, I just have yet to see a card that's got more than 512MB...

"It seems that Nvidia memory controller can handle more than we thought. We reported that R520 memory controller can address 1024MB and thought that was a big deal, but when we asked around, it turns that ATI can support even more than 1GB of graphic memory."
