Sony also unveiled the PS3's graphics chip, the RSX "Reality Synthesizer," which is based on Nvidia technology. The GPU will be capable of 128bit pixel precision, 1080p resolution, some of the highest HD resolution around. The RSX also has 512MB of graphics render memory and is capable of 100 billion shader operations and 51 billion dot products per second. It also has more than 300 million transistors, larger than any processor commercially available today. It will be manufactured using the 90nm process, with eight layers of metal. The RSX is more powerful than two GeForce 6800 Ultra video cards, which would cost roughly $1,000 total if purchased today.
The PlayStation 3 will also sport some hefty multimedia features, such as video chat, Internet access, digital photo viewing, and digital audio and video. Sony Computer Entertainment head Ken Kutaragi introduced it as a "supercomputer for computer entertainment."
To show off the PlayStation 3's graphical brawn, Sony showed several game demos, including an Unreal 3 tech demo of what appeared to be Unreal Tournament 2007. In what must come as a relief to developers, Epic Games' Tim Sweeney was on hand to vouch for the PS3, saying it was "easy to program for" and that Epic had received its first PS3 hardware two months ago. He proved the tech demo was real time by showing it again and by manipulating the camera and zooming in.
