EVGA E-GeForce 8400 Gs 512MB DDR3 Pci-e 2.0

NVIDIA SLI Technology
Dramatically scales performance by allowing two graphics cards to be run in parallel. Only available on select PCI-Express models.

NVIDIA® GigaThread™ Technology
GigaThread is a new technology that enables thousands of independent threads to execute in parallel inside of the graphics core. This delivers extreme processing efficiency in advanced, next-generation shader programs.

Full Microsoft® DirectX® 10 Shader Model 4.0 Support
Also known as the Unified Shader Model, the Vertex shaders, Geometry shaders, and Pixel shaders are combined in to one unified shader. Also backwards compatible with DirectX® 9.

True 128-Bit Floating Point High Dynamic-Range (HDR)
Allows you to experience cinematic, life like environments, for an amazing graphics experience.

PCI Express® 2.0 / 1.1 Support
Allows 500MB a lane or up to 8 GB/s at 16x speeds - allows for full support for new PCI-E 2.0 graphics cards.

NVIDIA® CUDA™ Support
Accelerates CUDA based applications through the GPU's proccessing power allowing for faster application performance such as video transcoding.

NVIDIA® PhysX™ Ready
Enjoy more visual immersion with life like physics for a more dynamic experience.

NVIDIA® PureVideo™ HD Technology
Smooth video, accurate colors, precise image scaling, video decode acceleration and post processing, all provided by the graphics card to give you the best HD experience possible. This feature also offloads from the CPU to help reduce power consumption.

Unified Shader Architecture
Provides an effecient single platform consisting of vertex shaders, geometry shaders, and the pixel shaders. This allows for better performance and visual quality.

NVIDIA® Lumenex™ Engine
A portion of the GPU is dedicated to delivering 16x full-screen antialisasing, 128-Bit Floating Point HDR, and support for 2560x1600 resolutions all at incredible image quality and performance.
