GeForce GTX 480 vs Radeon HD 5750 1GB

Intro

The GeForce GTX 480 has a GPU core clock speed of 700 MHz, and the 1536 MB of GDDR5 memory runs at 924 MHz through a 384-bit bus. It also features 480 Stream Processors, 60 TAUs, and 48 ROPs.

Compare those specs to the Radeon HD 5750 1GB, which comes with GPU clock speed of 700 MHz, and 1024 MB of GDDR5 memory running at 1150 MHz through a 128-bit bus. It also is made up of 720(144x5) Stream Processors, 36 Texture Address Units, and 16 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (in units of MB per second) that can be transported over the external memory interface within a second. The number is calculated by multiplying the interface width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR 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 texture units of the card by the core 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 processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines 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 fill 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 potential to reach the maximum fill rate.
