Nvidia and Sony provided a first look at the RSX graphics architecture of Playstation 3 at a press conference at E3. The RSX graphics processor when combined with the Cell microprocessor (which has nine cores) will provide two teraflops of floating point horsepower. PS3 will have 256MB of XDR RAM at 3.2 GHz, 256MB GDDR3 VRAM at 700 MHz, six USB 2.0 ports, support for Memory Stick and compact flash memory cards, digital audio output, 3 gigabit Ethernet ports, built-in Wi-Fi and support for Blue-ray Disc format (50GB) as well as play CDs and DVDs. At E3 the impressive tech demos included light absorption and subsurface refraction, highlighting how different surfaces react differently to lighting. More significantly to OpenGL developers, the Playstation 3 will support the open standards OpenGL ES 2.0 (with OpenGL ES Shading Language) and Cg for rendering.
