GeForce GTX 1060 vs GeForce GTX 660

Intro

The GeForce GTX 1060 makes use of a 16 nm design. nVidia has set the core speed at 1506 MHz. The GDDR5 RAM runs at a speed of 2000 MHz on this particular model. It features 1280 SPUs as well as 80 TAUs and 48 Rasterization Operator Units.

Compare those specifications to the GeForce GTX 660, which uses a 28 nm design. nVidia has clocked the core frequency at 980 MHz. The GDDR5 RAM is set to run at a frequency of 1502 MHz on this particular model. It features 960 SPUs as well as 80 Texture Address Units and 24 ROPs.

Memory Bandwidth: Bandwidth is the max amount of information (in units of MB per second) that can be transported past the external memory interface in one second. It is worked out by multiplying the interface width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
