GeForce GTX 660 vs GeForce GTX 980

Intro

The GeForce GTX 660 comes with a clock frequency of 980 MHz and a GDDR5 memory speed of 1502 MHz. It also makes use of a 192-bit bus, and uses a 28 nm design. It is comprised of 960 SPUs, 80 TAUs, and 24 ROPs.

Compare all that to the GeForce GTX 980, which features a core clock speed of 1126 MHz and a GDDR5 memory frequency of 1750 MHz. It also features a 256-bit bus, and uses a 28 nm design. It features 2048 SPUs, 128 Texture Address Units, and 64 Raster Operation Units.

Memory Bandwidth: Bandwidth is the largest amount of data (in units of MB per second) that can be moved across the external memory interface in a second. It is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total number of texture units of the card by the core 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 in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
