SiS315 T&L Graphics Chip
SiS announced its new product SiS315 - the first 256-bit 2D/3D high-performance graphic engine supporting Transform and Lighting (T&L) for the mainstream desktop PC. By integrating a H/W T&L into their VGA, the SiS315 sets a new standard for the mainstream desktop PC market. Commercial production of SiS315 is expected to start from December by SiS's foundry. The price per 10,000 units is USD30.
Up to now T&L engines only existed in 3D workstations and high-end desktop PC. The T&L engine which is located in front of rendering engine, is capable of doing complex per-vertex multiple transformation and light calculations, creating more accurate and brighter images for the viewer. Traditionally, for a PC platform without T&L engine, all these jobs have to be processed by the CPU before sending the result to the rendering engine. Therefore, the SiS315 3D chip can considerably off-load the CPU loading when running 3D Applications and allow more computing power to focus on fancy effects on the next generation 3D games or interactive applications.
AGP4x interface
up to 128MB memory. A
DDR DRAM interface is also supported
Memory bandwidth up to 5.3GB/s.
Built-in a motion compensation engine for DVD hardware acceleration.
256-bit engine
<emphasis>Supports dual display, LCD output and TV-out applications.</emphasis>
