NVIDIA GeForce GTX 660

The GeForce GTX 660 is a GPU from NVIDIA. This chip has an average gaming score at 14% in our GPU benchmark.

The GeForce GTX 660 has 3 GiB of GDDR5 memory, with a total memory bandwidth of 140 GB/s. The memory bus has a width of 192 bits. More memory is beneficial when gaming at high resolutions as the memory needs to store the frame buffer and all the game textures. If you run out of memory, you will experience poor performance as the GPU needs to swap data in and out of the memory as it is used.

In terms of clock speed, the GeForce GTX 660 GPU core runs at a frequency of 980 MHz and if power and temperature permits, it can boost up to 1032 MHz. The core clock is directly related to the performance of a GPU, the higher the clock, the more processing can be done per second. A higher clock does not guarantee better performance by itself, this also depends on the number of shading units and other elements of the pipeline.

The performance specs of the GeForce GTX 660 are a raw floating-point performance of 1.98 TFLOPS : this represents the number of floating point (decimal) operations completed per second. In addition, this NVIDIA GPU has a pixel rate of 21 Gigapixels/s, the number of pixels the GPU is capable of outputting every second. Furthermore, it has a texture fill rate of 83 Gigatexels/s, the number of pixels the GPU can renderer per second.

As for rendering API support, the GeForce GTX 660 supports up to DirectX 11. In addition, in cross-platform titles, OpenGL 4.5 features are supported. Newer APIs are usually more efficient, allowing for better performance in games and better graphical effects.

The raw technical specs of the GeForce GTX 660 are: 960 total shading units (general purpose parallel cores capable of processing different aspects of the graphics pipeline), 80 texture mapping units (specialised processors for texture operations, this determines the texture rate) and 24 render output processors or units (the final step in the rendering pipeline, responsible for rasterising the image)

Power and thermals for the NVIDIA GeForce GTX 660 are a TDP (Thermal Design Power) of 140 watts. This measures the amount of heat the GPU produces when running at 100%. This isn't a measure of power consumption, but it's a good estimate.
