GeForce GTX 480 vs Radeon HD 5750 1GB

Intro

The GeForce GTX 480 comes with a GPU core clock speed of 700 MHz, and the 1536 MB of GDDR5 memory is set to run at 924 MHz through a 384-bit bus. It also is made up of 480 SPUs, 60 Texture Address Units, and 48 Raster Operation Units.

Compare all of that to the Radeon HD 5750 1GB, which has GPU clock speed of 700 MHz, and 1024 MB of GDDR5 RAM set to run at 1150 MHz through a 128-bit bus. It also is comprised of 720(144x5) SPUs, 36 TAUs, and 16 Raster Operation Units.

Memory Bandwidth: Bandwidth is the max amount of information (measured in MB per second) that can be transported across the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory speed. If it uses DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better 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 is worked out by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the graphics 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 that the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
