Introduction
GIGABYTE TECHNOLOGY Co. Ltd. launches the GV-NX78T256VB-ED, yet another high definition next generation GIGABYTE Gaming VGA solution based on the NVIDIA GeForce 7800GT graphics processor. The new GV-NX78T256VB-ED introduces an incredible 20 pixel pipeline in what is arguably the industry's powerful and technically advanced graphics accelerator card. The new high-end VGA card from GIGABYTE boasts NVIDIA's top-three mainstream architectures, the Power of 3, which comprise Shader Model 3.0, HDR (High dynamic-range), and SLI technology, and also supports a host of industry wide technological advancements such as OpenGL 2.0 and Microsoft Vista® 64-bit operating systems.
CineFX 4.0 Engine
Through CineFX 4.0 engine that allows developers to create unique 3D game features and effects in both game animation and high-definition video. Gamers can get plus benefit from CineFX 4.0 that streamlines the creation of complex visual effects.
Intellisample™ 4.0
The industry's fastest antialiasing delivers ultra-realistic visuals, with no jagged edges, at lightning-fast speeds. Visual quality is taken to new heights through a new rotated grid sampling pattern, advanced 128 Tap sample coverage, 16x anisotropic filtering, and support for transparency supersampling and multisampling.
UltraShadow™ II
Enhances the performance of bleeding-edge games, like id Software's Doom 3, that feature complex scenes with multiple light sources and objects. 2nd-generation technology delivers more than 4x the shadow processing power over the previous generation.
Dual-link DVI
Able to drive the industry's largest and highest resolution flat-panel displays up to 2560x1600.
SLI™ Technology
Delivers up to 2X the performance of a single GPU configuration for unparalleled gaming experiences by allowing two graphics cards to run in parallel. The must-have feature for performance PCI Express graphics, SLI dramatically scales performance on 60 top PC games.
