GeForce GTX 660 Ti vs GeForce GTX Titan Black

Intro

The GeForce GTX 660 Ti makes use of a 28 nm design. nVidia has clocked the core speed at 915 MHz. The GDDR5 memory is set to run at a speed of 1500 MHz on this specific model. It features 1344 SPUs as well as 112 Texture Address Units and 24 Rasterization Operator Units.

Compare those specifications to the GeForce GTX Titan Black, which comes with a GPU core clock speed of 889 MHz, and 6144 MB of GDDR5 RAM set to run at 1750 MHz through a 384-bit bus. It also features 2880 SPUs, 240 TAUs, and 48 Raster Operation Units.

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of information (counted in megabytes per second) that can be moved over the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the video card will be at 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 can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
