GeForce GTX 480 vs GeForce GTX 660 Ti

Intro

The GeForce GTX 480 makes use of a 40 nm design. nVidia has clocked the core frequency at 700 MHz. The GDDR5 memory runs at a speed of 924 MHz on this card. It features 480 SPUs along with 60 TAUs and 48 Rasterization Operator Units.

Compare those specifications to the GeForce GTX 660 Ti, which uses a 28 nm design. nVidia has clocked the core speed at 915 MHz. The GDDR5 RAM is set to run at a frequency of 1500 MHz on this specific model. It features 1344 SPUs along with 112 Texture Address Units and 24 Rasterization Operator Units.

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

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number 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 output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
