GeForce GTX 660 Ti vs GeForce GTX 980

Intro

The GeForce GTX 660 Ti uses a 28 nm design. nVidia has clocked the core frequency at 915 MHz. The GDDR5 memory works at a speed of 1500 MHz on this particular model. It features 1344 SPUs as well as 112 TAUs and 24 Rasterization Operator Units.

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

Memory Bandwidth: Memory bandwidth is the max amount of information (in units of megabytes per second) that can be transferred over the external memory interface within a second. It is worked out by multiplying the interface width by its memory speed. If the card has DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster 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 number of texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
