94w ago - A few months back Sony stated that PlayStation 4 is expected to arrive with rival next-generation consoles, and today Forbes.com reports that PS4 is in development with AMD rumored to be building the system's graphics technology.
To quote: "Sony is working on an as-yet-unannounced new gaming console, former AMD employees say, and the processor designer may play a key role in the new product.
AMD's graphics technology is already used in Microsoft's XBox 360 console. However, Sony's PlayStation 3 - introduced in 2006 - relies on graphics technology from Nvidia.
AMD declined to comment on the project. Sony Chief Transformation Officer George Bailey also declined to discuss Sony's new console, or even acknowledge its existence.
However, at AMD's analyst day last month, AMD Chief Financial Officer Thomas Seifert identified gaming as one of several trends that will drive revenue growth at AMD in 2012."

System memory and video memory are used for different tasks and are generally not shared which is why the PS3 was limited. Sharing any of the system memory would pose issues considering it's pretty much always slower than VRAM. The 360 used GDDR3, the VRAM, for the entire system.
Well benchmarks should be done with a beastly CPU and almost always are. It's all about what the GPU can do assuming there is nothing in the way.
It's not like the 1GB is entirely for textures, that's absolutely all the GPU has to work with, everything else including any form of AA takes memory as well. The last time I cranked up the textures in a game it took almost 2GB.
