Kepler GPU Architecture

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.



Up until now, GPUs have operated at a fixed clock speed when playing 3D games, even if they have the potential to run faster. GPU Boost intelligently monitors graphics work load and increases the clock speed whenever possible. The result is that the GPU always performs at its peak and you get the highest framerate possible.

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.

NVIDIA 3D Vision™ Ready

NVIDIA 3D Vision® Ready1

NVIDIA 3D Vision brings a fully immersive, stereoscopic 3D experience to the PC. A combination of high-tech wireless glasses and advanced software, 3D Vision transforms hundreds of PC games into full stereoscopic 3D. Get up to 2x monitor and keyboard brightness with NVIDIA 3D LightBoost technology4. In addition, you can enjoy 3D movies and 3D digital photographs from in eye popping, crystal-clear quality.

NVIDIA Surround with Up To Four Monitors

NVIDIA Surround with Up To Four Monitors2

Nothing is as breathtaking as playing your favorite games across three monitors. At 5760 x 1080, the expanded field of view fully engages human peripheral vision and provides for the most immersive experience in racing and flight simulators. Add in a fourth display to keep tabs on chat, email or web while you are gaming.

Two New Anti-aliasing Modes: FXAA and TXAA

TXAA AntiAliasing

Antialiasing helps to smooth out jagged lines in games. Existing techniques like MSAA are effective at removing jagged lines in still images but struggle with crawling and shimmering artifacts when the player is in motion. TXAA is a new antialiasing mode that combines MSAA, temporal filtering, and post processing for the highest edge quality and minimal shimmering during gameplay.

NVIDIA SLI Technology

NVIDIA SLI® Technology3

Used by the most demanding gamers worldwide, SLI lets you link up to three GeForce GTX 660 together for astounding performance. And with NVIDIA's track record for fast and frequent software updates, you'll not only get the best performance in existing games, but future games too.

NVIDIA PhysX Technology

NVIDIA PhysX® Technology

Full support for NVIDIA PhysX technology, enabling a totally new class of physical gaming interaction for a more dynamic and realistic experience with GeForce.

1 - NVIDIA 3D Vision requires 3D Vision glasses and a 3D Vision-Ready monitor. See for more information.
2 - 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 for more information.
3 - A GeForce GTX 660 GPU must be paired with another GeForce GTX 660 GPU (graphics card manufacturer can be different) with the same frame buffer size. SLI requires sufficient system cooling and a compatible power supply. Visit for more information and a listing of SLI-Certified components.
4 - Requires NVIDIA 3D LightBoost monitor or notebook.
