SPARKLE GeForce GT640 2048MB DDR3 OC Dragon Cyclone
Kepler GPU Architecture
NVIDIA's Kepler GPU architecture has been designed from the ground up not just for maximum performance in the latest DirectX 11 games, 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.
DirectX 11
Microsoft DirectX is the graphics technology powering all of today's hottest games. The latest version— DirectX 11—features tessellation for film-like geometric detail, compute shaders for custom graphics effects, and improved multithreading for better hardware utilization.
CUDA
CUDA is a parallel computing platform and programming model invented by NVIDIA. It enables dramatic increases in computing performance by harnessing the power of the graphics processing unit (GPU).
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.
PhysX
Without accurate physics simulations, even the most beautiful game feels static and lifeless. PhysX taps into the GPU for complex physics calculations. Used by popular games such as Alice: Madness Returns, PhysX brings games to life with dynamic destruction, particle based fluids, and life-like animation.
3D Vision
NVIDIA 3D Vision? technology delivers stereoscopic 3D images for gamers, movie-lovers and photo enthusiasts when configured with NVIDIA GPUs, NVIDIA 3D Vision active shutter glasses, and 3D Vision-Ready display/projector. Only NVIDIA 3D Vision supports the richest array of 3D content available - more than 600 3D games, Blu-ray 3D movies, 3D photos and streaming YouTube 3D videos.
Blu-ray 3D Support
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
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.
TrueHD and DTS-HD Audio Bitstreaming
Full support for TrueHD and DTS-HD advanced lossless multi-channel HD audio codecs brings the rich sound of the master recording to your living room.
RoHS Compliant
Sparkle products are RoHS-compliant, effectively reducing the environmental impact by restricting the use of lead, mercury and certain other hazardous substances in the products.
