Introduction
Introduction
The high performance 3D graphics card uses the Accelerated Graphics
Port (AGP) interface. AGP utilizes a dedicated pipeline to access system
memory for texturing, z-buffering and alpha blending.
Equipped with the Intel740 graphics chip, its HyperPipelined 3D
architecture provides the following features: Precise Pixel Interpolation
(PPI), Parallel Data Processing (PDP) and Direct Memory Execution (DME).
Precise Pixel Interpolation delivers good image quality, Parallel Data
Processing allows consistent high performance and Direct Memory
Execution delivers 528MB/sec bandwidth providing seamless access to
system memory for unlimited texture sizes and rich rendering. The graphics
chips 3D architecture enables maximum memor y bandwidth for sustained
3D performance and exceptional image quality in PCs equipped with
the Pentium II processor and AGPset.
Use the graphics card with softwares that support 3D and enjoy more
texture and higher screen resolution at higher frame rates. The graphics
card will deliver faster and better graphics to your PC.
