Radeon HD 5750 512MB 73600 MB/sec
GeForce GT 240 GDDR5 54400 MB/sec
Difference: 19200 (35%)

Texel Rate

The Radeon HD 5750 512MB is quite a bit (more or less 43%) faster with regards to anisotropic filtering than the GeForce GT 240 GDDR5. (explain)

Radeon HD 5750 512MB 25200 Mtexels/sec
GeForce GT 240 GDDR5 17600 Mtexels/sec
Difference: 7600 (43%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon HD 5750 512MB is a better choice, by far. (explain)

Radeon HD 5750 512MB 11200 Mpixels/sec
GeForce GT 240 GDDR5 4400 Mpixels/sec
Difference: 6800 (155%)

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.

Memory Bandwidth: Bandwidth is the maximum amount of information (in units of megabytes per second) that can be transported over the external memory interface in a second. It is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the 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 number of texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, 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 most pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
