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 and 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. Speaking of video, Sony Computer Entertainment's chief technical officer Masa Chatani was on hand to show off the PS3's panoramic video functions. Since the console has two HD outputs, it is can be hooked up to two side-by-side HDTVs to projecting video in a 32:9 extra-widescreen format (think Cinemascope in your living room). Like a gigantic version of the Nintendo DS, the dual digital outputs also allow for an extended game display, with the action on one screen and either game information or video chat on the second. Out of the box, the PS3 will have the capability to support seven Bluetooth controllers, which can be used for nearly 24 hours before they require charging. Later, pictures of the controllers themselves were released, showing their almost boomerang-like shape. It will also have six USB slots for peripherals: four up front and two in the back. As rumored, it will also have Wi-Fi connectivity to the PSP, which can be used as a remote screen and/or controller.
Dr. Richard Marx, the inventor of EyeToy, was on hand to show off the PS3's wireless HD IP Camera. The demo recalled rumors that the machine will have Minority Report-esque motion-sensing capabilities. Marx held two small cup-like objects in his hands, which moved the cups on the screen in real time.
To show off the PlayStation 3's graphical brawn, Sony showed several game demos, including an Unreal 3 engine show-off 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.
