GTX 660

See how NVIDIA is redefining smooth, seamless, lifelike gaming.

The new Kepler GeForce GTX 600 Series offers record breaking performance and has been applauded by the press and users all over the world. Today, Club 3D introduces the GeForce GTX 660, a mid-range card and smaller brother of the award winning GeForce GTX 660Ti. This card offers an excellent upgrade for users of cards such as the GeForce GTX 260, GTX 460, GTX 560Ti, providing smooth performance and better gaming experience for the latest game titles.

The GeForce GTX 660 supports DirectX 11 rendering, which lets games take advantage of visual features such tessellation, PhysX onboard physics processing and GPU Boost, which dynamically increases the card's clock speed if the thermal and electrical headroom exist. Loaded with 960 CUDA parallel processing cores and a based clock of 980MHz which can boost to as much as 1033MHz. It is powered by 2GB of GDDR5 memory operating over a 192 bit interface, similar to his bigger brother the GeForce GTX 660Ti providing 6Gbps data rate. Output connectors will be two dual-link DVI, one HDMI, and one DisplayPort 1.2.

Amazing gaming performance

GTX 660 performance comparison3DMark 11

3DMark 11 is the latest version of the world's most popular benchmark. Designed to measure your PC's gaming performance 3DMark 11 makes extensive use of all the new features in DirectX 11 including tessellation, compute shaders and multi-threading. Trusted by gamers worldwide to give accurate and unbiased results, 3DMark 11 is the best way to consistently and reliably test DirectX 11 under game-like loads.

Battlefield 3

Battlefield 3 is one of the world's most popular first person shooter titles and set the benchmark for real-time gaming performance introducing state-of-the-art technologies that allows you to experience superior animation, unparalleled lighting and special effects, delivering enhanced visual quality, a grand sense of scale, massive destruction and incredible gameplay.

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.

GPU Boost

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 PhysX technology helps games play better and feel better by making interaction with environments and characters far more realistic than ever before. By making behavior more realistic, the graphics look and “feel” better.

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.

SurroundNVIDIA Surround with Up To Four Monitors

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.

TXAATwo New Anti-aliasing Modes: FXAA and TXAA

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.

The second mode, TXAA, is an in-game option that combines MSAA, temporal filtering, and post processing for even higher visual fidelity.

3D VisionNVIDIA 3D Vision® Ready

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 3DVisionLive.com in eye popping, crystal-clear quality.


NVIDIA SLI® Technology

Used by the most demanding gamers worldwide, SLI lets you link up to two GeForce GTX 660's 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.

SLI intelligently scales graphics performance by combining multiple GeForce GPUs on a SLI certified motherboard. With over 1,000 supported applications and used by over 94% of multi-GPU PCs on Steam, SLI is the technology of choice for gamers who demand the very best.

Beyond just better performance, SLI offers a host of advanced features. For PhysX games, SLI can assign the second GPU for physics computation, enabling stunning effects such as life-like fluids, particles, and destruction. For CUDA applications, a second GPU can be used for compute purposes such as Folding@home or video transcoding. Finally, for the ultimate in image quality, SLI Anti-aliasing offers up to 64xAA with two GPUs.


Performance per Watt

Compared to the original Fermi SM, SMX has twice the performance per Watt. Put another way, given a Watt of power, Kepler's SMX can do twice the amount of work as Fermi's SM. And this is measured apples-to-apples, on the same manufacturing process. Imagine a conventional 50 Watt light bulb that shines as brightly as a 100 Watt light bulb—that's what Kepler's like when gaming.

Protective capsDust can collect inside unused video outputs and Electro-Static-Discharge (ESD) by touching the PCB with bare hands while not grounding yourself can be harmful to a graphic card. To protect against dust and ESD Club 3D provides protective caps on the video outputs, SLI connector(s) and PCB goldfinger of the graphic card and can prolong the lifespan of your graphic card by up to 65%.
