GeForce 8800 GTX vs Radeon HD 5750 512MB

Intro

Compare all of that to the Radeon HD 5750 512MB, which comes with core speeds of 700 MHz on the GPU, and 1150 MHz on the 512 MB of GDDR5 memory. It features 720(144x5) SPUs along with 36 Texture Address Units and 16 Rasterization Operator Units.

Pixel Rate

If running with a high resolution is important to you, then the GeForce 8800 GTX is the winner, and very much so. (explain)

GeForce 8800 GTX		13800 Mpixels/sec
Radeon HD 5750 512MB		11200 Mpixels/sec
	Difference: 2600 (23%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of MB per second) that can be moved over the external memory interface in a second. The number is worked out by multiplying the bus width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total amount of texture units of the card by the core clock 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 applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
