The NVIDIA GeForce GTX 660 graphic card was released on September 2012. This video card features a graphic processing unit stacked with 960 cuda cores running at a clock speed of 980 MHz. The GeForce GTX 660 has a memory capacity of 2048 MB GDDR5. The memory transfer rate of this video card is 144.2 GB/s.
Performance And Power
The GeForce GTX 660 can produce a total computing power of 1983.36 GFLOPS. In addition, this graphic can reach a pixel fill rate of 20.66 Gigapixels/s and a texture fill rate of 82.64 Gigatexels/s. The GeForce GTX 660 graphic card consumes up to 140 W of power.
The GeForce GTX 660 graphic card can be plugged to a motherboard through the support of a PCI-E 3.0 x 16 bus. In addition, the NVIDIA GeForce GTX 660 can support up to Up to 4 displays monitors and supports the following display connectors: "DisplayPort, Dual Link DVI-D, Dual Link DVI-I, HDMI". This video card supports a resolution of up to 2560 x 1600 using the DVI connector
The GeForce GTX 660 supports the following libraries: " DirectX 11.1, OpenCL 1.2, Shader Model 5.0 ". OpenGL is a cross language and multi-platform application programming interface for rendering 2D and 3D vector graphics. OpenGL is used to interact with a GPU to harness Hardware-accelerated rendering and eliminates the need to recompile shaders making it an efficient and performance oriented standard. Microsoft DirectX is an Application programming Interface for the Windows operating systems which Integrates well with AMD and NVIDIA GPUs. The Microsoft DirectX 10 is a significant step in 3D graphics. It features a highly optimized runtime, powerfull geometry sharders, and many other features. The Microsoft DirectX 11, introduced with Windows 7, brings numerous improvement over its precedessor DirectX 10. It is designed to be more efficient, supports sophisticated shading and texturing techniques and levearage the use of multi processors, resulting in smoother 3D animations. The open computing language (OpenCL) is programming interface used for general purpose programming across CPUs and GPUs and other processors. The standard gives developers the portability and efficiency of heterogeneous processing platforms.
Scalable link interface (SLI)
The Scalable link interface (SLI) technology enables the combination of multiple graphic cards on a single Motherboard. The GeForce GTX 660 uses a 3-way SLI, which let you connect up to three (3) graphic cards on the same computer. This scalability is possible with the use of a high speed digital interface that mantains the data flow between the connected graphics cards, and with the use of dynamic load balancing and advance rendering capabilities to orchestrate the data and graphical processing tasks.
Aliasing is a problem that can be observer in digital media such as image, videos, video games, and audio recording, In Video games, Aliasing can be observer through visual effects such flickering and as pixelated object edges. The Aliasing effects could be improved or suppressed by the use of Anti-Aliasing techniques. One of the Anti-Aliasing technologies supported by the GeForce GTX 660 graphic card is the The NVIDIA Fast Approximate Anti-Aliasing Technology (FXAA). The NVIDIA Fast Approximate Anti-Aliasing Technology (FXAA) is a technology that enhance the image sharpness and quality with great performance efficiency. The GeForce GTX 660 supports the temporal anti-aliasing (TXAA) technology. The NVIDIA TXAA is an anti-aliasing technique used to reduce temporal aliasing such as flickering and crawling that can be observed during the game motions.
The NVIDIA PhysX game engine enhance the level of realism to the game experience, and allow more realistic scenes and game dynamics effects such as explosion, smoke, fluid dynamics, characters and objects movements, and much more.
The NVIDIA 3D vision let you watch videos and movies, and play games in 3D stereoscopy view with the use of 3D glasses. This technology supports any type of screen however a screen with a frame ratio of 120Hz or more is recommended.
3D Vision Surround
With the VIDIA 3D VISION Surround Technology, it is possible to experience surround 3D vision using multiple displays. It let you expand the view of the game on multiple munitor to get a surrond image experience.
HDCP, High Brandwidth Digital Content Protection
The NVIDIA high bandwidth digital content protection is designed to protect audio and video content being transferred from the NVIDIA GPU over DVI and HDMI cable to a display device. Both sending and receiving devices must be HDCP compliant.
