Thanks to our GPU Benchmark, we have measured the NVIDIA GeForce GTX 660 as a bad gaming performer a score of 8%.
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. A clock speed is the frequency at which the GPU updates. A higher speed means more processing can happen per cycle. This is useful only when comparing cards of the same generation, as other architectures may process more or less per clock.
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. Higher level APIs such as DirectX 12 give more control to the game developer and can allow them to improve the graphics and performance.
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.
