GeForce GTX 480 vs GeForce GTX 660 Ti

Intro

The GeForce GTX 480 uses a 40 nm design. nVidia has set the core frequency at 700 MHz. The GDDR5 RAM runs at a frequency of 924 MHz on this specific card. It features 480 SPUs as well as 60 TAUs and 48 ROPs.

Compare that to the GeForce GTX 660 Ti, which makes use of a 28 nm design. nVidia has clocked the core frequency at 915 MHz. The GDDR5 RAM works at a frequency of 1500 MHz on this particular model. It features 1344 SPUs as well as 112 Texture Address Units and 24 Rasterization Operator Units.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called 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 bandwidth is, the lower the ability to get to the max fill rate.
