Overview

Every PC deserves great graphics. The NVIDIA® GeForce® GT 640 graphics card taps into the powerful next-generation GeForce architecture to deliver premium multimedia performance and reliable PC gaming — every time.

Kepler Architecture

Kepler Architecture

Kepler is our most advanced GPU architecture yet. Optimized for DirectX 11, Kepler is not only fast, but ultra power efficient.

Smoother Framerates

Smoother Framerates

Adaptive V-Sync intelligently renders each frame to minimize tearing while maximizing performance.

Features

Kepler GPU Architecture

Kepler GPU Architecture

NVIDIA's Kepler GPU architecture has been designed from the ground up not just for maximum performance, but optimal performance per watt. The new SMX streaming multiprocessor is twice as efficient as the prior generation and the new geometry engine draws triangles twice as fast. The result is world class performance and the highest image quality in an elegant and power efficient graphics card.

 
NVIDIA Surround with Up To Four Monitors

NVIDIA Surround with Up To Four Monitors1

Simultaneously drive up to four independent 1080p displays for the ultimate multimedia or productivity workspace and expand a single application across all three displays for an immersive viewing perspective.

 
3D Blu-Ray Support

3D Blu-Ray Support2

Connect your PC to any 3D enabled TV over HDMI and enjoy a cinematic 3D experience in your home with seamless support for 1080p Blu-ray 3D discs.

 
NVIDIA Adaptive Vertical Sync

NVIDIA Adaptive Vertical Sync

Nothing is more distracting than framerate stuttering and screen tearing. The first tends to occur when framerates are low, the second when framerates are high. Adaptive V-Sync is a smarter way to render frames. At high framerates, V-sync is enabled to eliminate tearing, at low frame rates, it's disabled to minimize stuttering. It gets rid of distractions so you can get on with gaming.

 
New Anti-aliasing Mode: FXAA

New Anti-aliasing Mode: FXAA

Anti-aliasing smoothes out jagged edges but can be demanding on framerates. FXAA is a new antialiasing technology that produces beautiful smooth lines with minimal performance impact. And with Kepler based GPUs, you'll be able to enable FXAA in hundreds of game titles through the NVIDIA Control Panel.

 

1 - NVIDIA 3D Vision Surround requires 3D Vision glasses and three matching 3D Vision-Ready displays. In addition a DisplayPort to Dual-link DVI adapter may be required to connect one of the 3D Vision Surround monitors. See www.nvidia.in/surround for more information.
2 - NVIDIA 3D Vision requires 3D Vision glasses and a 3D Vision-Ready monitor. See www.nvidia.in/3dvision for more information.
